INTRODUCTION

DescriptionThe Light Commercial Building Solution (LCBS) is a family of control devices designed to meet the comfort control requirements of commercial buildings of small to medium size. Commercial buildings typical of this market include but are not limited to office buildings, retail stores, light manufacturing facilities, restaurants, schools, churches, theaters, super markets, grocery stores, and banks.

These buildings typically use some combination of single zone air handling units, heat-pumps, zoned air handling units, variable air volume systems, fan coil units, unit ventilators, and/or perimeter heating to maintain the building�s comfort levels. In addition, lighting control, equipment on-off scheduling, and data collection may be required of the control system.

Light Commercial Building Solution devices utilize the LonWorks® communication protocol for open systems network communications. The controllers may also be used for stand-alone control applications.

The Light Commercial Building Solution includes thermostats and a number of application specific controllers (Excel 10) to directly address typical mechanical systems. The advantage of application specific controllers is use of a sophisticated and efficient control strategy matched to the mechanical equipment functions, standardizing the control processes, and minimizing the effort required to configure and maintain the system insuring consistent performance.

LCBS also includes a selection of Building Manager and general purpose controllers (Excel 15) to address the need for custom applications and to handle alarm reporting, data collection and reporting, and operator interface communications.

Operator interface to a LCBS may be with an easy to use command display unit, LONSTATION� workstation software installed in a personal computer, or by internet access.

The system is configured using LONSPEC� software installed in a personal computer. LONSPEC� simplifies system configuration by letting the user select the desired control options while most networking functions are done �behind the scene�.

Specialized applications of LCBS are available as RapidZone� for zoning systems and LonStat� for thermostat only solutions.

Control ApplicationsTypical Light Commercial Building Applications:� Single zone air handling unit thermostat control for up to 3

stages of heat and 3 stages of cooling.� Single zone air handling unit control for up to 4 stages or

modulating heating and 4 stages or modulating cooling with integrated economizer control.

� Heat pump air handling unit control for up to 4 compressors (heating and cooling) and 4 stages of auxiliary/emergency heat and integrated economizer control.

� Unit ventilator control with ASHRAE cycle 1, 2, or 3 selection.

� Fan coil unit control� Fin tube radiation and convector control.� Variable air volume terminal unit control.

Mandatory Mechanisms/Objects/Network Variables⎯ Mandatory mechanisms, object and network variables that are implemented in all of the Excel 10 devices.

NamedObject⎯Objects that have names are called NamedObjects. These objects are visible on the network as functional independent entities and are accessed by name. Typical examples of NamedObjects are controllers, control loops and logic function blocks.

NEC⎯National Electrical Code; The body of standards for safe field-wiring practices.

NEMA⎯National Electrical Manufacturers Association; The standards developed by an organization of companies for safe field wiring practices.

Network Management Node⎯A LONWORKS® node that is responsible for configuring the network, installing the nodes, binding the network variables between nodes and general network diagnostics.

Network Object�See Object

Network Time Master⎯A network time master will be the only device sending out the time/date. All other network devices will use the time/date from the network time master (even if they have their own real-time clock). Network time master is chosen/configured from LONSPEC� and remains unchanged until re configured, even in the event of a failure on the network time master. (The Excel 15 W7760C can not be the network time master.)


74-3679�1 8

Network Time Scheduler⎯The network time scheduler sends out current and next state (occupied, unoccupied or standby) and time until the next change of state (TUNCOS) to all of its control loops based on the configured schedules.

Network Variables⎯A class of variables defined in Neuron C that allow communication over the LONWORKS® network to other nodes on the network. For example; An output network variable in one node can be bound to the corresponding input network variable(s) in other node(s). Changing the value of the output network variable in one node causes the new value to be automatically communicated to the bound input network variable(s) in other node(s). When an input network variable is updated, an nv_update_occurs event is posted at the receiving node(s) so that the application program can take action based on the change. A network management node that explicitly reads and/or writes the network variable can also poll network variables. Network variables can contain one data field (one or two bytes) or multiple data fields (a structure).

Node⎯A Communications Connection on a network; An Excel 15 or Excel 10 Controller is one node on the LONWORKS® Bus network.

NV⎯Network Variable; An Excel 15 or Excel 10 parameter that can be viewed or modified over the LONWORKS® Bus network.

Object�Also referred to as control object or network object. A single control algorithm with multiple input, output, setpoints, and/or configuration parameters. Each XL10 application specific controller is a single object. Each start/stop loop, control loop, and logic function in an XL15 controller is a unique object.

PC⎯An Personal Computer with Pentium processor capable of running Microsoft® Windows™.

Plant Controller⎯A device that can be used to monitor and control HVAC equipment and other miscellaneous loads in a distributed network.

Proportional Control⎯A control algorithm or method in which the final control element moves to a position proportional to the deviation of the value of the controlled variable from the setpoint.

Proportional Integral (PI) Control⎯A control algorithm that combines the proportional control and the integral reset control algorithms. Integral reset virtually eliminates offset by gradually shifting the controlled output in the direction that brings the controlled variable back to the setpoint.

Proportional Integral Derivative (PID) Control⎯A control algorithm that enhances the PI control algorithm by adding a component that is proportional to the rate of change (derivative) of the deviation of the controlled variable. PID compensates for system dynamics and allows faster control response rate reset.

PWM⎯Pulse Width Modulated output; Allows analog modulating control of equipment using a digital output on the controller.

RapidLink�RapidLink� is an RS232 and telephone line compatible serial device that allows any host (PC) with an RS 232 or Modem interface (and the necessary driver software) to communicate with a LonWorks® network.

RCD⎯Remote Communication Device; For the Building Management System, this is a piece of hardware that is functionally compatible to an SLTA and provides access directly to the LONWORKS® Bus.

SYSTEM ARCHITECTURES

OverviewThe Light Commercial Building Solution (LCBS) offers five distinctive solution architectures designed to address specific market requirements.

All five LCBS architectures utilize the Echelon® LONWORKS® Free Topology (FTT-10A) data communications bus for low cost and high performance open system communications.

The LCBS architectures use various combinations (sub-sets) of Excel 15, Excel 10, T7350, and T7300F/Q7300H control devices. The differentiation in the architectures is the application, configuration tool and/or user interface.

The five LCBS architectures are:� XL15A (LONSTATION�)� XL15B (Internet)� RapidZone� LonStat� Unconfigured CVAHU

In addition, the XL10 application specific controllers and T7300, and T7350 commercial programmable thermostats can be used as stand-alone controllers with no network connections.

Fig. 1 depicts the options available in the XL15A architecture.

The XL15A - LONSTATION� solution offers the most comprehensive LCBS solution. Network management functions including scheduling, alarm handling, and dial-out are performed by one or more Excel 15 W7760A Building Managers (XL15A). All Excel10 application specific controllers, T7350 and T7300F/Q7300H thermostats, Excel 15 W7760C Plant Manager, NX VFD, CXS AND CXL variable frequency drives are supported by the W7760A Building Manager. LONSTATION� provides a cost effective, user friendly operator interface.

See Table 3 for a complete list of devices supported and a comparison of architecture features.

The system is configured using ZL7760A LONSPEC� software configuration tool.

Local and remote system monitoring is performed using ZL7762A LONSTATION� Software Monitoring and Graphics software.

NOTE: The W7760B Building Manager is not supported in the XL15A architecture and should not be used with the W7760A Building Manager. While both the W7760A and W7760B may coexist on the same LONWORKS® bus, they do not support each other and network functions may conflict if implemented in both devices.

Networking ConsiderationsNETWORK CONSTRAINTSThe maximum number of devices on a LCBS LONWORKS® bus is 120. This does not include LONTALK® adapters. The maximum number of devices on a subnet segment is 60. If more than 60 devices are used on a network, a Q7740A or B repeater is required.

The recommended maximum LONWORKS® bus cable length of a network segment is 9,200 feet (2,800 meters) with a Q7740 repeater and 4,600 feet (1,400 meters) without a repeater. The cable wire gage network topology will also determine the maximum cable length that can be used.

The maximum number of W7760A Building Managers on a sub-network is 4.

The maximum number of W7761A RIO devices is 3 per W7760A and/or C.

In an XL15A solution further limitations on the number of devices on a bus may result from alarm handling and data sharing requirements.� Each W7760A will support a maximum of 20 nodes

(W7760C, XL10 controllers, T7350 and T7300F/Q7300H thermostats) for device internal alarms. Refer to Excel 15 W7760A Building Manager Application Guide 74-2969 for alarm data.

� The maximum number of devices with internal alarm reporting is 84 (4 W7760A plus 4 X 20 external = 84). Additional 120 devices can be used. However, only 84 devices can be configured to report internal alarms.

� Each W7760A supports a maximum of 20 analog and 20 digital user configured alarms. User configured alarms can be configured for any analog or digital point in the system. The maximum number of user configured alarms are 80 analog and 80 digital.

� Each W7760A will support a maximum of 16 Trend Logs. A trend log is a single analog or digital point. A tend log can be configured to use any point in the system. The maximum number of trend logs is 64.

� Each W7760A will support a maximum of 15 Run Time logs. A run time log may be configured for any single digital point in the system. The maximum number of run time logs is 60

� Each W7760A will support a maximum of 20 Bypass Logs. A bypass log may be configured for any control object bypass state. The maximum number of bypass logs is 80.

The T7300F/Q7300H thermostats can schedule a maximum of 4 XL10 controllers, W7760C Plant Controller start-stop and control loops, and other T7300F/Q7300Hs whereas the T7350 can schedule all the 120 controllers on the network. T7350 can schedule only one Excel 15C object for every Excel 15C Plant controller.

NOTES:� The T7300F/Q7300H has only two Occupied and

two Unoccupied settings per day, no standby set-tings, uses a 7 day schedule with no temporary or holiday schedules, and does not support adaptive intelligent recovery in W7760C control loops and XL10 controllers.

� The T7350 has four settings (occupied, unoccu-pied, or standby) per day, uses a eight day sched-ule with a maximum of 10 holidays.

Alarm HandlingAll alarm reporting and logging is done by one or more W7760A Building Managers on the subnetwork. It requires that each device to be alarmed be mapped to a W7760A. Each W7760A will support a maximum of 20 other network devices for alarm reporting. Devices that are not mapped to a W7760A will not have alarms reported.

The W7760A Building Manager is configured to route alarms it processes. The alarms can be configured to be ignored (Do Nothing) or sent to any combination of dial-out to remote LONSTATION�, sent to local LONSTATION� and S7760A Command Display, and/or log to the W7760A alarm log. See Excel 15 W7760A Building Manager System Engineering (74-2969) for complete details on alarm handling.

S7760A COMMAND DISPLAYThe S7760A Command Display module can be configured to display data from a maximum of 270 network objects. Each LCBS network device is a network node object. In addition each individual start-stop loop, control loop, and logic loop configured in a W7760A or W7760C is a network object. Each W7760A can be configured for as many as 15 network objects (node + 8 start-stop + 6 control). Each W7760C can be configured for as many as 51 network objects (node + 8 start-stop + 10 control + 32 logic). The S7760A will support a maximum of 4 W7760A Building Manager node objects, a maximum of 10 W7760C Plant Controller node objects, and any combination of Excel10 application specific controller objects and Excel 15 control objects, not exceeding the limit of 270 network objects total.


74-3679�1 12

NOTE: Few control objects from a W7760A or C are config-ured for display in a S7760A Command Display.

The S7760A Command Display module can be configured to display alarm information from a W7760A Building Manager. To display the alarm data, the W7760A node object must be configured in the S7760A.

DATA SHARINGRefer to section �LonSpec Data Sharing� on page 38.

Configuring data sharing in LONSPEC� is primarily done as the individual controllers are already configured and requires no additional action by the user. However, the use of standard network shared points such as Outside Air Temperature and Economizer Enable must be configured using the �Refer Points� screen. See �Refer Points Applications� on page 40.

The LONSPEC�configuration screen �Refer Points� sorts the available destination points based on the source point. The sorting is based on the LonWorks® Standard Network

Variable Type (SNVT) which may include many controller variables that are very different in function. Refer to �Appendix A - Refer Points Tables� on page 43 for a complete listing of appropriate points for data sharing.

The W7760A Building Manager limit of scheduling a maximum of 20 network devices can be circumvented using �Refer Points� to share the schedule data to additional devices. See �Time of Day Scheduling� on page 40.

When using a single wall module with more than one Excel 10 controller, it is necessary to use �Refer Points� to share the wall module data from the source controller to the destination controller(s).

Data sharing for W7751 VAV terminal unit applications requires very specific attention to the application requirements. Refer to Excel 10 W7751B,D,D,F,H,J Variable Air Volume Controller Application Guide 74-2949 for specific application details and �XL10 VAV Terminal (W7751)� on page 39 for specific information on data sharing.

Fig. 2 depicts the options available in the XL15B Solution architecture.

The XL15B architecture utilizes the internet to access the LCBS system. The W7760B performs the network management functions and is a secure web server providing multi-user access to the system operating data, alarm and trend logs, and schedules using Microsoft® Internet Explorer (6.0 or higher) web browser.

The W7760B Building Manager supports:� W7760C&D Plant Controllers� W7750A,B,C CVAHU controller� W7751B,D,F,H,J VAV II controllers and Smart Actuators� W7753A Unit Ventilator controller� Q7300H Communicating sub-base for T7300 � T7350 Communicating sub-base� W7761A Remote Input Output Device� W7762A,B Hydronic Device� W7763C Cold Ceiling Device� W7752D,E,F,G,J Fan Coil Unit

CAUTIONThe S7760A Command Display will not support reading or changing schedules nor will it support alarm handling.The S7760A supports only W7760A Building Manager for scheduling and alarm handling. These functions are not available when using a W7760B Building Manager.

The S7760A can be used to read controller data and change setpoints and execute commands. The constraints are the same as those described for the XL15A solution, although, there will be no W7760A Building Manager in the mix of network objects.See page 11.

The W7760B will recognize and list other LONMARK® compliant devices including third party devices on the LONWORKS® bus but will not access them to read or write data. Following are the LCBS devices that are not supported:� ZL7762A LONSTATION�� W7760A Building Manager� S7760A (CD2) Command Display� Q7760A SLTA� RapidLink�� W7790A RF Gateway� XFL521 4-Digital Input Output Device

CAUTIONThe W7760A Building Manager is not supported in the XL15B architecture and must not be used with the W7760B Building Manager. While both the W7760A and W7760B may coexist on the same LONWORKS® bus, they do not support each other. It might result in conflicting of network functions if implemented in both devices. See Table 3 for a complete list of devices supported and a comparison of architecture features.

The W7760B Building Manager is configured using internal software tools. The remaining system devices are configured using ZL7760A LONSPEC� software configuration tool.

Networking ConsiderationsNETWORK CONSTRAINTSThe maximum number of devices on a LCBS LONWORKS® bus is 120 excluding LONTALK® adapters. The maximum number of devices on a subnet segment is 60. If more than 60 devices are used on a network, a Q7740 repeater is required.

The recommended maximum LONWORKS® bus cable length of a network segment is 9,200 feet (2,800 meters) with a Q7740 repeater and 4,600 feet (1,400 meters) without a repeater. The cable wire gage network topology will also determine the maximum cable length that can be used.

The maximum number of W7760B Building Managers on a sub-network is 1.

The maximum number of W7761A RIO devices is 3 per W7760C. You can use an RIO device on the network that is not associated with an W7760C strictly for monitoring the inputs. There will be no output control for that device.

The W7760B Building Manager is a web server. Precautions must be taken to insure appropriate LAN, WAN, and/or internet security to protect the server from unauthorized access.

WARNINGFailure to provide adequate internet security will result in unauthorized access to the W7760B Building Manager with severe consequences.

ALARM HANDLINGAll alarm handling is executed by the W7760B Building Manager.

Critical alarms are e-mailed to designated recipients.

The W7760B Building Manager supports multiuser access for operators.

The W7760B does not support the S7760A Command Display. Alarms cannot be routed to the W7760A.

Alarm data is accessible by internet if the user has access authorization.

Configuration ConsiderationsLONSPEC� (ZL7760A) is required to configure the supported controllers in XL15B solution. Since LONSPEC� is used to configure all LCBS control devices, the user must exercise care not to add devices that are not supported by the W7760B to the network.

In addition, Excel 15B can be a network interface when performing the following functions from LONSPEC�:

� Downloading all XL 10 and XL 15 devices' configurations.� Performing online functions like device diagnostics and

calibration.� Performing Device Discovery� Commission and configuration of Excel 15B from

LONSPEC�.� Upload or download Excel 15B configuration like alarms,

trends, schedules, and DLC loads from/to LONSPEC�.


15 74-3679�1

Refer to LONSPEC� online help or LONSPEC� User�s Guide (form 74-2937).

Initial setup of the W7760B requires a PC running Windows® Hyper Terminal VT100 emulation that needs to be directly connected to the serial port of the W7760B.

The scheduling, alarm handling, DLC, and trend logging are configured using the W7760B Building Manager internal configuration capability and LAN, WAN, or internet access.

The W7760B Building Manager does scheduling for all supported devices on the LONWORKS® Network.� 20 Schedules� 20 alternate weekly schedules� 50 Holidays� 50 Temporary schedules

The W7760B Building Manager does Alarm Management for all supported devices on the LONWORKS® Network. All devices� internal alarms are automatically mapped.

Critical alarms can be configured to send e-mail annunciation to designated recipients.

A maximum of 500 user defined alarms can be configured.

The W7760B automatically creates a trend log for each supported XL10, XL15C plant controller, NXS/NXP/NXL VFD, T7350 and T7300F/Q7300H on the network.

The W7760B supports a maximum of 100 user created trend logs of 10 points each.

The W7760B does Building Management using DLC that monitors the building�s rate of energy consumption.

� Excel 15B supports a maximum of 50 load assignments across 120 objects.

� Each such load or a group of loads is further connected to an Excel 10 or Excel 15C output relay or an external load object.

� An XL 15C can be selected as the Pulse Meter input.

RapidZone Architecture

Fig. 3. RapidZone Solution Architecture

Fig. 3 depicts the options available in the RapidZone architecture. Refer to the RapidZone Solution Application Guide (74-3449) for a detailed description.

RapidZone consists of the ZL7751A software configuration tool and is a subset of LCBS, designed specifically to meet the requirements of the zoned air handling systems market. The application uses the W7760C,D to control the air handling unit(s) and W7751J to control the individual zones.

RapidZone supports a maximum of 10 air handling units each with a maximum of 18 zones. The total number zones is limited by the network maximum of 120 devices.

The W7760A Building Manager is optional. It may be used to support scheduling and alarm handling. One W7760A may be used to schedule a maximum of 4 zoning units and associated zones. A single W7760A manages alarms for 1 W7760C RTU

Controller and 18 W7751J Zone Controllers. The number of W7760As required in a system is determined by the number of RTU�s that must have alarm reporting. A maximum of 10 W7760A�s can be used on a RapidZone LONWORKS® bus.

The term RTU used throughout the RapidZone documentation includes all the W7760C, CVAHU and Q7300 devices used in zoning applications.


Networking ConsiderationsThe ZL7751A RapidZone Configuration tool can be directly connected to the LonWorks® bus or connected via modem. Refer to LonWorks® for LCBS - Networking Considerations (form 74-2865).

The maximum number of devices on a LCBS LONWORKS® bus is 120 excluding LONTALK® adapters.

A RapidZone solution may have a maximum of 10 W7760A Building Managers, 10 W7760C Plant Managers (RTU controllers), and 18 W7751H,J Smart actuators for every W7760C. The maximum number of RTUs (any combination of W7760C, W7750, Q7300) on the network cannot exceed 50. Ensure that it does not exceed the total sub-network limit of 120 devices.

A Q7760A Repeater is required if the number of devices exceeds 60 or if the bus cable length exceeds the maximum allowable segment length.

ZL7762A LONSTATION� monitoring software can be used locally (direct connect) or remotely using a modem.

Configuration ConsiderationsIf a RapidZone configuration is to be imported into a LONSPEC� project that needs to be included in an XL15A architecture, the maximum number of XL15A�s in the RapidZone project is 10. However, when restored into LonSpec only the first four XL15A's can be modified. In order to be able to modify all W7760A's on the network through LONSPEC�, the total number of W7760A's configured in RapidZone must be limited to four.

If a RapidZone configuration is to be imported into a LONSPEC� project to be included in an XL15B architecture, no W7760A�s can be used. Scheduling and alarm handling must be configured with the W7760B Building Manager.

In both cases if S7760A Command Displays are to be used they should be configured in the LONSPEC� project and not in RapidZone.

Fig. 4 depicts the options available in the LonStat architecture.

LonStat Solution Architecture

Fig. 4. LonStat Solution Architecture.

A LonStat solution consist of T7300F commercial programmable thermostats with Q7300H communicating sub-base configured with ZL7300A LonStat configuration and monitoring software. A LonStat solution is used in the traditional commercial thermostat market when a communicating thermostat is required. LonStat does not support any other device. LONWORKS® compatible devices can reside on the same LONWORKS® bus but ZL7300A LonStat software will not recognize them.

T7300F/Q7300H thermostats do no support mechanical system alarms such as high or low limits, fan failure, or dirty filter. T7300F/Q7300H diagnostic alarms are reported when ZL7300 LonStat is used to monitor the specific thermostat in alarm.

Key advantages of using LonStat solution when compared to a traditional free standing commercial programmable thermostat installations are:� Current temperatures and setpoints can be checked

remotely with LonStat connected directly or remotely.� Setpoints, time, schedules, and bypass can be changed

with LonStat connected direct or remotely.

� With master time keeping, all thermostats maintain the same time. Changing the master time keeper will update all other thermostats within one minute.

� With master scheduling, multiple thermostats can be �zoned� to maintain the same schedule. Changing the schedule of a single thermostat changes the schedule for all thermostats in the zone.With a discharge air sensor installed, mechanical system troubleshooting can be done remotely.

Networking ConsiderationsZL7300A LonStat will communicate with only one thermostat at a time.


Configuration ConsiderationsZL7300 LonStat does not create a database. It must be connected to the LONWORKS® bus directly or remotely by modem. LonStat reads all configuration and operating data directly from the thermostat. Changes made with LonStat are downloaded to the thermostat, no record of the configuration is retained on the PC. Since no LonStat database exists, a LonStat solution cannot be restored to LONSPEC�.

LonStat and LONSTATION� can be used to monitor a LonStat solution both locally and remotely.

The T7300F/Q7300H thermostat/sub-base has no configurable alarms. Internal diagnostic alarms are displayed in LonStat and LONSTATION� only when the thermostat is selected for monitoring.

Unconfigured CVAHU Architecture

Fig. 5. Unconfigured CVAHU Architecture

Fig. 5 depicts the options available in the Unconfigured CVAHU solution architecture.

The Unconfigured CVAHU Solution architecture provides a - no configuration XL10 constant volume air handling unit solution (use it directly out of the box). The W7750A,B,C controllers are the only control devices supported in this option. Monitoring is not supported as part of this solution.

Each unconfigured W7750 controller provides the control functions of a T7300 thermostat. The bypass and setpoint inputs if used, will work individually for the W7750 to which it is connected.

The Unconfigured CVAHU solution is a simple cost effective alternative to programmable thermostats especially when night setback is required for multiple air handling units running on the same schedule. This solution uses a simple wall module without the complexity of a programmable thermostat, simplifying operation for the user.

Since no configuration programming is required for the W7750�s the cost of installing the network is offset by lower labor cost.

The Unconfigured CVAHU solution does not require the installer to be knowledgeable of direct digital control system operation. Simply install the controllers, wire them, turn on the power, and the job is done.

The factory default configuration for all models of the W7750 controller sets digital input 1 as a time clock input and digital input 2 as Schedule Master. Placing a jumper across digital input 2 causes the Schedule Master controller to broadcast the occupancy mode. W7750 controllers that do not have the jumper will automatically follow the schedule of the one that does. Only one W7750 on the LONWORKS® bus can be designated as the Schedule Master.

WARNINGDownloading to a W7750 CVAHU controller from any configuration tool overwrites the factory default settings and the automatic binding capability is lost and cannot be restored. The W7750 controller factory default configuration settings must be accepted for all functions. Refer to Excel 10 W7750A,B,C Application Engineering manuals for complete details on factory default configuration.

Networking ConsiderationsAll devices must be connected to the LONWORKS® FTT-10 bus.

A maximum of 120 W770 CVAHU controllers can be connected to the network.

Zoning for multiple schedules can be created by adding multiple networks each with it�s own time clock and master scheduler jumper installed on one and only one W7750.

Configuration ConsiderationsNo configuration is required. The Unconfigured CVAHU solution uses the factory defaults.

The factor defaults for the Excel 10 W7750 CVAHU controllers includes an algorithm that binds all controllers without the Schedule Master input (digital input 2) to the one on the network that does have the input jumpered. A time clock is connected to the Time Clock input (digital input 1). The scheduled occupancy state of the Schedule Master W7750 is then shared to all others on the network.

LONTALK® adapters are used to connect PCs� to the LONTALK® bus. The function of LONTALK® is to convert the data from the PC communication format to the LONWORKS® protocol.

Selection of the type of adapter depends on the computer and application. The Q7752B laptop and PCLTA-10/20 desktop are installed in the PC and can only be used for directly connecting the PC to the LONWORKS® bus. The external Q7760A LONTALK® Adapter or Q7770A RapidLink Dial-up Network Adapter is required for modem connection to the PC.

LONTALK® adapters connected directly to the bus are automatically configured. Only a Q7760A or Q7770A RapidLink Dial-up Network Adapter (Q7760A used with a modem) requires configuration with LONSPEC�, RapidZone or LONSTAT�.

The practical limit to the number of LONTALK® adapters connected to a single network is 3: one directly connected to a PC running LONSTATION�, another directly connected to a PC running LONSPEC�, and one more connected remotely by a modem to a PC running either LONSPEC�, or LONSTATION�. Multiple directly connected PCs� running either LONSPEC� or LONSTATION� can result in data collisions leading to communication failures.

Configuration ToolsThe following are the three software configuration tools that can be used to configure LCBS solutions:

LONSPEC� (ZL7760A)LONSPEC� is the general purpose configuration tool used to configure all LCBS network devices. LONSPEC� is required to configure XL15A and XL15B solutions. LONSPEC� can be used to monitor systems if no automatic dialing is required.

RAPIDZONE (ZL7751A)RapidZone is an application driven configuration tool used to configure W7760C Plant Manager, W7750A,B,C and T7300F/Q7300H single zone RTU, W7751J Smart Actuator, W7760A Building Manager, and S7760A Command Display for commercial zoning applications. Device configuration is automatic based on application data entered into the tool. RapidZone projects with 10 or less W7760A Plant Managers can be restored to LONSPEC�. RapidZone can be used to monitor RapidZone systems if support for automatic dialing is not required.

NOTE: LONSPEC� can only configure the first four W7760A Controllers on the network.

LONSTAT� (ZL7300A)LonStat� is an application driven configuration and monitoring tool used in projects that are comprised exclusively of T7300F/Q7300H commercial programmable thermostats. LonStat can be used only to configure the thermostats and monitor thermostat data. No alarm reporting is supported.

APPLICATION STEPSOverviewThe application steps shown in Table 4 are planning considerations for engineering a Light Commercial Building Solution. These steps are guidelines intended to aid understanding: selection of appropriate control devices, selection of appropriate operator interface devices and software, LONWORKS® bus arrangement choices, power requirements, network device configuration options, and system startup and commissioning.

Table 4. Application Steps.

Step 1. Plan the SystemReview the plans and specifications, system requirements documentation, sales estimates, and/or any other documents defining control system operation, user interface functions, and data management requirements to determine the LCBS architecture best suited for the project.

The Light Commercial Building Solution (LCBS) was developed to address the HVAC control requirements typically found in small to medium sized commercial buildings. For large complex buildings, the EXCEL 5000 Open system provides an appropriate solution.

When planning the system layout, consider potential expansion possibilities to allow for future growth. Planning is very important to enable addition of HVAC systems and controllers in future projects.

The first consideration in selecting the architecture is what monitoring and data gathering requirements exist. This selection will determine the Building Manager that needs to be used, if any. LONSTATION� is used to monitor XL15A, RapidZone, and LonStat� solution architectures.

The XL15B solution is monitored with Microsoft® Internet Explorer and requires a local area network (LAN), wide area network (WAN), or internet connection.

WARNINGDo not install the W7760A and W7760B Building managers on the same network. Both devices may co-exist on the same network, but scheduling, alarm handling, and logging are configured with different tools (probability of data conflict is high).LONSPEC� supports both the W7760A and W7760B. LONSPEC� also uses W7760B as a network interface to connect online. W7760B has internal configuration settings and does not support the W7760A.

Refer to Table 3 LCBS Architecture Comparison for a brief comparison of W7760A and W7760B Building Manager capabilities.

Select the controllers that are supported by the application. Excel10 application specific controllers are available for HVAC equipment typically used in the target market. These include constant volume air handling units (CVAHU), variable air volume terminal units (VAV II), fan coil units (FCU), unit ventilators (UV), Hydronic units (HYD), Remote Input/Output unit (RIO), Chilled Ceiling Controller (CHC), thermostats and valve applications (fin tube radiation, convector, manual fan FCU, unit heater). T7350 and T7300F/Q7300H thermostats are available for applications requiring programmable thermostats. Refer to the respective Excel 10 controller, T7350 and/or T7300F/Q7300H Application Guide for specific information regarding input/output requirements, controller operation, and configuration. See Table 1 on page 5 to identify literature for a specific controller.

The XL15 controllers (W7760A,C) are used for custom applications such as mechanical room control, variable volume air handling units, specialized air handling systems, lighting control, and equipment scheduling.

Command Display (CD and CD2) allows viewing and modifying the parameters of other units over the LonWorks® network.

Refer to the respective Excel 15 controller Application Guide for specific information regarding input/output requirements, controller operation, and configuration. See Table 1 on page 5 to identify literature for a specific controller.

Other units are:� CXS/CXL Honeywell Variable Frequency Drive (VFD)

The Excel VRL CX/CXL/CXS frequency drive is used for controlling speed and torque of three-phase AC motors. Excel VRL CX/CXL/CXS frequency converters can be connected to LonWorks® network by using CX203OPT option board. They can then be controlled, monitored, and programmed from the LonWorks® network.

� Vacon NX Variable Frequency Drive (NXS/NXP/NXL VFD)Vacon NX frequency converter (NXVFD) is used to control speed and torque of three-phase AC motors. Refer to www.Vacon.com for more information on NX VFD. The NX VFD can be connected to LonWorks® network using NXOPTC4 option board. They can then be controlled, monitored, and programmed from the LONWORKS® network through LONSPEC�.

Determine the input and output device requirements for each controller used in the system. Select input and output devices compatible with the controller and the application. Consider the operating range, wiring requirements, and the environment conditions when selecting input/output devices. When selecting actuators for modulating applications consider using floating control. In direct digital control applications floating actuators will generally provide control action equal to or better than an analog input actuator for lower cost.

Determine the location of controllers, sensor, actuators and other input/output devices and create wiring diagrams. See �Step 3. Prepare Wiring Diagrams� on page 29.

The application engineer must review the Direct Digital Control (DDC) job requirements. This includes the Sequences of Operation for the W7760A,C Controllers, and for the system as a whole. Usually there are variables that must be passed between the W7760A,C Controllers and other Excel 10 controller(s) that are required for optimum system wide operation. Typical examples are the TOD, Occ/Unocc signal, the outdoor air temperature, the demand limit control signal, and the smoke control mode signal.

It is important to understand these interrelationships early in the job engineering process to ensure implementation when configuring the controllers. Refer to the controller Application Guides (see Table 1 on page 5), the LONSPEC� ZL7760A software Help for configuring information for LCBS devices, and �LonSpec Data Sharing� on page 38.

The LONWORKS® Bus FTT-10A communication wiring between controllers is a free topology scheme that supports daisy chain, T-tap, star, and/or loop, wiring configurations. Refer to the LONWORKS® Bus Wiring Guidelines form,74-2865 for complete description of network topology rules. See Application Step 2. Lay Out Communications and Power Wiring for more information on bus wiring layout, and see Application Step 4. Prepare Wiring Diagrams, for wiring details.

The Light Commercial Building Solution implementation of LonWorks® supports 1 subnet per network while routers are not supported. Since there is only 1 sub-network per network in the LCBS, all capabilities and limitations of a sub-network apply to the network. The term network is often used in lieu of sub-network in LCBS discussions.

A sub-network supports a maximum of 127 nodes. Each LONWORKS® Bus device constitutes one node.

A maximum of 120 LCBS devices can be configured on a single LONWORKS® Bus sub-network. LONSPEC� and RapidZone reserves seven nodes for LONTALK® adapters for connecting software tools. The remaining 120 nodes are used for LCBS devices.

If the number of LCBS devices on the sub-network exceeds 60, a Q7740 repeater is required.

In an XL15A solution further limitations on the number of devices on a bus may result from alarm handling requirements.� The maximum number of W7760A Building Managers on a

sub-network is 4. � The maximum number of W7761A RIO devices is 3 per

W7760A and C.� The maximum number of external nodes that can be

mapped to a W7760A will support is 20.� The maximum number of nodes with alarm reporting is 84

(4 W7760A plus 4 X 20 external = 84). Additional devices may used up to the maximum of 120. However, only 84 devices will report alarms.

� Each W7760C control loop function� Each W7760A can support alarm handling for a maximum

of 20 network objects in addition to itself and the associated W7761A�s. Each control device on the network is 1 object effectively limiting the sub-network to 96 control devices In addition each W7760C Plant Manager control loop and logic loop is a network object.

� Each W7760A and C, Excel 15 controllers will support a maximum of 3 W7761A Remote Input/Output (RIO) devices. A W7761 must be associated with a W7760A or C and cannot be associated to more than 1 W7760A or C. Therefore, the maximum number of W7761A�s in a network is limited to 3 times the number of W7760A and C�s.

Refer to LonWorks® for LCBS (form number 74-2865_2) for complete description of network topology rules and the maximum wire length limitations. If a longer LONWORKS® Bus sub-network is required, a Q7740 Repeater can be added to extend its length. Each sub-network can have a maximum of one repeater.

All LONWORKS® Bus segments require a termination device. Doubly terminated daisy-chain requires 2 termination devices. For more details on LONWORKS® Bus termination, refer to LonWorks® for LCBS - Cable Termination (form number 74-2865_2) or see Application Step 3. Lay Out Communications and Power Wiring, and the LONWORKS® Bus Termination Module subsection in Application Step 4.

Step 2. LayOut Communications and Power Wiring

CommunicationsThe LONWORKS® Bus communications bus is a 78 kbps serial link that uses transformer isolation and differential Manchester encoding.

Installation of communications wiring requires special considerations that may vary from project to project. It is important that exact installation instructions be provided to the installer.

Guidelines for communications wiring are as follows:� All field wiring must conform to local codes and ordinances.� Approved cable types for LONWORKS® Bus communications

wiring is Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated unshielded, twisted pair conductors. For non-plenum areas, Honeywell U.S. part AK3781 (one pair) or U.S. part AK3782 (two pair) can be used. In plenum areas, U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair) can be used. Additionally, Echelon® approved cable can be used. Contact Echelon® Corp. Technical Support for the recommended vendors of Echelon® approved cables (refer to LonWorks® for LCBS - Network Cabling and Connections - Table 8 through 12, form 74-2865).

� Unswitched 24 Vac power wiring can be run in the same conduit as the LONWORKS® Bus cable.

� Do not bundle output wires with sensors, digital inputs, or communications LONWORKS® Bus wires.

� Do not use different wire types or gauges on the same LONWORKS® Bus segment. Using different wire types or gauges can result in line impedance changes that can cause unpredictable reflections on the LONWORKS® Bus.

� In noisy (high EMI) environments, avoid wires running parallel to noisy power cables, motor control centers, or lines containing lighting dimmer switches, and keep at least 3 in. (76 mm) of separation between noisy lines and the LONWORKS® Bus cable.

� Each LONWORKS® Bus segment containing up to 120 (see Table 18) Excel 15/10 Controllers, T7350s, T7300F/Q7300Hs, Command Displays, requires the installation of a 209541B Termination Module for a single terminated


74-3679�1 26

LONWORKS® Bus or two 209541B Termination Modules for a doubly terminated LONWORKS® Bus. For more details on LONWORKS® Bus termination, refer to LonWorks® for LCBS - Cable Termination (form number 74-2865_2).

� Make sure that neither of the LONWORKS® Bus wires is grounded.

� LONWORKS® Bus cable extended to T7770 Wall Modules to connect the LONWORKS® jack must be included in the total wire length.

NOTE: For specific wiring details, see Step 4. For wall module wiring, use U.S. part AK3782 (non-plenum) or U.S. part AK3792 (plenum). For an LONWORKS® Bus that is a doubly terminated daisy-chain, these cables contain two twisted pairs (one for the run to the wall module, and one for the run back to the controller) for ease of installation.

� If a longer LONWORKS® Bus segment is required, a Q7740 Repeater can be added to extend its length. Each sub-network can have a maximum of one repeater. If a Q7740 repeater is used, each sub-net segment must be terminated as described (refer to LonWorks® for LCBS - Cable Termination (form number 74-2865_2).

NOTE: Special consideration must be given to connecting the LONWORK®S Bus to the W7760A Building Manager and W7760C Plant Manager. Each is built with 2 pairs of terminals for connecting the bus. The jumper between the terminal pairs is on the controller printed circuit board. Removing the controller from the sub-base will interrupt the bus circuit. To maintain sub-net circuit continuity install jumpers between terminals or install the �in� and �out� bus cable on the same terminals. See W7760 LonWorks® Wiring Option Fig. 6 through 8.

Fig. 6. W7760 LonWorks wiring option 1.



PowerA power budget must be calculated for each device to determine the required transformer size for proper operation. A power budget is simply the summing of the maximum power draw ratings (in VA) of all the devices to be controlled. This includes the controller itself and any devices powered from the controller such as equipment actuators (ML6161, or other motors) and various contactors and transducers.

IMPORTANT� If a controller is used on Heating and Cooling

Equipment (UL 1995, U.S. only) and transformer primary power is more than 150 volts, connect the transformer secondary common to earth ground.

� When multiple controllers operate from a single transformer, you must connect the same side of the transformer secondary to the same power input terminal in each device. The earth ground terminal (W7760C Terminal 49) must be connected to a verified earth ground for each controller in the group.

POWER BUDGET CALCULATION EXAMPLEThe following is an example power budget calculation for a typical W7760C Excel 15 Plant Controller. While the example is shown for a W7760C the process is applicable for all LCBS controllers.

Assume a W7760C unit with a fan, two stages of D/X cooling, modulating steam valve for heating, and modulating economizer dampers. The power requirements are:

The W7760C System example requires 41.9 VA of peak power; therefore, a 75 VA AT88A Transformer could be used to power one controller of this type, or a 100 VA AT92A Transformer could be used to power two of these Plant Controllers and meet NEC Class 2 restrictions (no greater than 100 VA). See Fig. 44 and 45 for illustrations of power wiring details. See Table 5 for VA ratings of various devices.

Table 5. VA Ratings For Transformer Sizing.

For contactors and similar devices, the in-rush power ratings should be used as the worst case values when performing power budget calculations. Also, the application engineer must consider the possible combinations of simultaneously energized outputs and calculate the VA ratings accordingly. The worst case, that uses the largest possible VA load, should be determined when sizing the transformer.

Each W7760C requires 24 Vac power from an energy-limited Class II Power Source. To conform to Class II restrictions (U.S. only), transformers must not be larger than 100 VA. A single transformer can power more than one W7760C Controller. Fig. 9 shows a generic power wiring diagram for multiple devices using one transformer.

IMPORTANTUse the heaviest gauge wire available, up to 14 AWG (2.0 mm2) with a minimum of 18 AWG (1.0 mm2), for all power and earth ground wiring.

Screw type terminal blocks are designed to accept only one 14 AWG (2.0 mm2) conductor. Two or more wires that are 14 AWG (2.0 mm2) can be connected with a wire nut. Include a pigtail with this wire group and attach the pigtail to the terminal block.

GUIDELINES FOR POWER WIRING ARE AS FOLLOWS:� For multiple controllers operating from a single transformer,

the same side of the transformer secondary must be connected to the same power input terminal in each device. The earth ground terminal must be connected to a verified earth ground for each controller in the group. See Fig. 9. Controller configurations are not necessarily limited to two devices, but the total power draw including accessories cannot exceed 100 VA when powered by the same transformer (U.S. only).

� Many LCBS controllers require all loads to be powered by the same transformer that powers the controller.

� Keep the earth ground connection wire run as short as possible. Refer to Fig. 9.

� Do not connect earth ground to controller digital or analog ground terminals. Refer to Fig. 9.

� Unswitched 24 Vac power wiring can be run in the same conduit as the LONWORKS® Bus cable.

� Maintain at least a 3 in. (76 mm) separation between Triac outputs and LONWORKS® Bus wiring throughout the installation.

Fig. 9. Power wiring details for multiple LCBS Devices.

Line LossLCBS Controllers must receive a minimum supply voltage of 20 Vac. If long power or output wire runs are required, a voltage drop due to Ohms Law (I x R) line loss must be considered. This line loss can result in a significant increase in total power required and thereby affect transformer sizing. The following example is an I x R line-loss calculation for a 200 ft. (61m) run from the transformer to a W7760C Controller drawing 37 VA using two 18 AWG (1.0 mm2) wires.

The formula is:Loss = [length of round-trip wire run (ft.)] x [resistance in

wire (ohms per ft.)] x [current in wire (amperes)]From specification data:

18 AWG twisted pair wire has 6.52 ohms per 1000 feet.Loss = [(400 ft.) x (6.52/1000 ohms per ft.)] x

[(37 VA)/(24V)] = 4.02 volts

This means that four volts are going to be lost between the transformer and the controller; therefore, to assure the controller receives at least 20 volts, the transformer must output more than 24 volts. Because all transformer output voltage levels depend on the size of the connected load, a larger transformer outputs a higher voltage than a smaller one for a given load. Fig. 10 shows this voltage load dependence.

In the preceding I x R loss example, even though the controller load is only 37 VA, a standard 40 VA transformer is not sufficient due to the line loss. From Fig. 10, a 40 VA

transformer is just under 100 percent loaded (for the 37 VA controller) and, therefore, has a secondary voltage of 22.9 volts. (Use the lower edge of the shaded zone in Fig. 10 that represents the worst case conditions.) When the I x R loss of four volts is subtracted, only 18.9 volts reaches the controller, which is not enough voltage for proper operation.

In this situation, the engineer basically has three alternatives:1. Use a larger transformer; for example, if an 80 VA

model is used an output of 24.4 volts minus the four volt line loss supplies 20.4V to the controller. See Fig. 10. Although acceptable, the four-volt line-loss in this example is higher than recommended. See the following IMPORTANT note.

2. Use heavier gauge wire for the power run. 14 AWG (2.0 mm2) wire has a resistance of 2.57 ohms per 1000 ft. which, using the preceding formula, gives a line-loss of only 1.58 volts (compared with 4.02 volts). This would allow a 40 VA transformer to be used. 14 AWG (2.0 mm2) wire is the recommended wire size for 24 Vac wiring.

3. Locate the transformer closer to the controller, thereby reducing the length of the wire run, and the line loss.

The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. The same formula and method are used. The rule to remember is to keep all power and output wire runs as short as practical. When necessary, use heavier gauge wire, a bigger transformer, or install the transformer closer to the controller.

IMPORTANTNo installation should be designed where the line loss is greater than two volts to allow for nominal operation if the primary voltage drops to 102 Vac (120 Vac minus 15 percent).

To meet the National Electrical Manufacturers Association (NEMA) standards, a transformer must stay within the NEMA limits. The chart in Fig. 10 shows the required limits at various loads.

With 100 percent load, the transformer secondary must supply between 23 and 25 volts to meet the NEMA standard. When a purchased transformer meets the NEMA standard DC20-1986, the transformer voltage regulating ability can be considered reliable. Compliance with the NEMA standard is voluntary.

General ConsiderationsATTACHING 2 OR MORE WIRES TO THE SAME TERMINALFor field wiring, when attaching two or more wires, other than 14 AWG (2.0 mm2), to the same terminal, twist wires together. See Fig. 22. Deviation from this rule can result in improper electrical contact.

Wire to the terminal blocks as follows:1. Strip 1/2 in. (13 mm) insulation from the conductor.2. If using a single wire in the required terminal location,

cut the wire to 3/16 in. (5 mm) insert and tighten the screw to complete the termination.

3. If two or more wires are being inserted into one terminal location, twist the wires together a minimum of three turns before inserting them.

4. Cut the twisted end of the wires to 3/16 in. (5 mm) before inserting them into the terminal and tightening the screw.

NOTES:� Pull on each wire in all terminals to check for good

mechanical connection.� Consider adding Fig. 22 and the above notes to

the project wiring diagrams.

Step 5. Configure ControllersControllers are configured using ZL7760A LONSPEC�, ZL7751A RapidZone, or ZL7300A LonStat� configuration software tools. Refer to the individual LCBS controller Application Guide for complete information on configuring the controller. For a list of controllers and literature see �Applicable Literature� on page 5.

The following identifies the tools used for each of the 5 solution architectures:� XL15A Solution - ZL7760A LONSPEC�.� XL15B Solution - ZL7760A LONSPEC� (The W7760B

Building Manager has an internal setup function).� RapidZone Solution - XL7751A RapidZone software.� LonStat� - ZL7300A LonStat software. (LONSPEC� can

be used but LonStat� is simpler for the user.)� Unconfigured CVAHU - None, the controllers use factory

default parameters. Any software download will delete the factory default parameters.

Projects configured with RapidZone can be saved as a LONSPEC� backup database and restored to LONSPEC� to include the RapidZone Solution in an XL15A or XL15B Solution. While it is possible to manually configure a RapidZone application using LONSPEC�, the task is extremely complex and tedious.

LonStat� does not create a database. It must be connected to one or more T7300F/Q7300H communicating commercial programmable thermostats to be used.

A LONSPEC� database backup including one created in RapidZone can be associated to ZL7762A LONSTATION� monitoring software to significantly reduce the time required to commission LONSTATION�.

LONSTATION� can be used to monitor the XL15A Solution, the RapidZone Solution, and the LonStat� Solution. It cannot be used to monitor the XL15B Solution or Unconfigured CVAHU Solution.

Step 6. System StartupSystem startup assumes that the controller has been configured in a software tool and that some, if not all network devices have been installed. It is preferred that all devices be operational, but recognized that projects may be brought on line over time.

The major concern for projects being started over time is that the data sharing may not be complete to meet application needs. There is also a risk of electrical damage to one or more network devices if a device is connected to the network while the network is operational.

Check Installation and Wiring:Inspect all wiring connections at the controller terminals, and verify compliance with job drawings. If any wiring changes are required, first be sure to remove power from the device before starting work. Pay particular attention to:� 24 Vac power connections. Verify that multiple devices

powered by the same transformer are wired with the transformer secondary connected to the same input terminal identification on each controller. See Fig. 9. Controller configurations are not necessarily limited to two devices, but the total power draw including accessories cannot exceed 100 VA when powered by the same transformer (U.S. only).

� Device wiring. Be sure that each device is wired to a verified earth ground using a wire run as short as possible with the heaviest gauge wire available, up to 14 AWG (2.0 mm2) with a minimum of 18 AWG (1.0 mm2) for each controller in the group. See Fig. 9.

� Verify Triac wiring to external devices uses the proper load power/24 Vac hot terminals. Check for 24 Vac with a meter.

NOTE: All wiring must comply with applicable electrical codes and ordinances or as specified on installation wiring diagrams.

VERIFY TERMINATION MODULE PLACEMENTThe installation wiring diagrams should indicate the locations for placement of 209541B Termination Module(s). Refer to LONWORKS® Bus Wiring Guidelines (form number 74-2865_2) and the Excel 10 FTT Termination Module Installation Instructions form, 95-7554. Correct placement of the termination module(s) is required for proper LONWORKS® Bus operation.

Power UpApply power to the controller(s). Observe for any physical signs of malfunctions.

Observe the LED on the controller. The LED provides a visual indication of the status of the device. When the controller receives power, the LED should appear in one of the following allowable states:

1. Off - no power to the processor.2. Continuous On - processor is in initialized state.3. Slow Blink - controlling, normal state.4. Fast Blink - when the controller has an alarm condition.

See below for additional information on alarms.

Assigning Neuron® IDEach LCBS device communicating on the network has a neuron number assigned to the transceiver by the chip manufacturer. This number is printed on a 3 part identification label attached to each device. One part of the label is permanently affixed to the device and the other 2 parts are removable gummed labels that can be affixed to job documentation.

Assigning a Neuron® ID allows a device on the LONWORKS® Bus to be positively identified. The controller Neuron® ID number can be used to confirm the physical location of a particular Excel 15, Excel 10, T7350, T7300F/Q7300H, VFD, and NX VFD.

There are two methods of assigning a Neuron ID for an LCBS controller. One uses a hardware service pin button on the controller and manually entering the Neuron ID is the second.

When an Assign ID command (use the service pin button is issued from LONSPEC�, RapidZone, or LonStat�, the configuration tool goes into the SERVICE_MESSAGE mode for five minutes. In the SERVICE_MESSAGE mode, pressing

the hardware service pin button on a controller causes the Service Message to be broadcast on the network. All other functions are normal in the SERVICE_MESSAGE mode. Use of the Service Pin assures that the correct device is being selected for configuration download from the tool.

When manually entering the Neuron® ID and issuing the Assign ID command, LONSPEC�, RapidZone, or LonStat� locates and communicates directly with the controller (the controller does not go into the SERVICE_MESSAGE mode in this case). Refer to the LONSPEC� ZL7760A software Help for more information on the ID assignment process.

AlarmsIn addition to the following information, refer to the Installation Instructions and Checkout and Test manual for each product. See the �Applicable Literature� on page 5 for form numbers.

When an LCBS controller has an alarm condition, it reports it to the central node on the LONWORKS® Bus (typically, a W7760A or W7760B Building Manager). Information contained in an alarm message is:� Subnet Number:

LONWORKS® Bus segment that contains the node that has the alarm condition.

� Node Number:Node that has the alarm condition.

� Alarm Type: Specific alarm being issued.

Download the ConfigurationOnce the tool has the neuron® ID it can download the controller configuration to the controller. The download may take several minutes for each controller. The files being downloaded are shown in the download screen of the tool.

CheckoutOnce the configuration has been downloaded to the controller, the controller operation can be checked. Refer to the controller documentation to determine what procedures should be followed for checkout. The configuration tool can be used to monitor the controller to check the operation. Some controllers permit the configuration tool to manually override the outputs, others do not.

LONSPEC DATA SHARING

Introduction to Data SharingData sharing for the Light Commercial Building Solution (LCBS) is configured using one of the LCBS configuration tools; LONSPEC� ZL7760A, RapidZone, or LonStat. The LCBS configuration tools configure the data sharing as part of the configuration process and automatically selects the communication mechanisms as appropriate. A brief overview of the mechanisms used is helpful in planning a system configuration.

The LONWORKS® communications protocol uses a number of mechanisms to transfer data from one network device to another. This discussion is limited to 2 mechanisms used to share data between 2 or more devices on a LONWORKS® network in the Light Commercial Building Solution and is a brief and simplified summary of the function of these 2 communications mechanisms. For complete and detailed information on LonWorks® operation, refer to published documentation available from Echelon® Corp.

Data sharing or the exchange of data between 2 or more devices on a LONWORKS® network in the light commercial building solution uses one of two communication mechanisms, polling or binding.

Polling is a process in which one device on the network request data from another device on the network. The originating device sends a message requesting the data from a specific device and that device responds with the specific data requested. If the originating device needs data from multiple controllers it must send an individual request to each controller from which it needs data. In this case the polling device is configured to request data from a single or multiple network devices. The most common use of polling is, supervisory devices such as LONSTATION�, W7760A or B Building Manager, W7760C Plant Controller, S7760A Command Display Module, and LONSPEC� monitoring system. Another example is configuring a controller to use a �remote� point as an input. In LONSPEC�, RapidZone, and LonStat all polling is configured automatically as the network devices are configured.

Binding is the process where one device is configured to read data being transmitted by another device. The device originating the data is not sending the data to any specific device on the network, but any and all devices configured to read the data will do so. In this case the device receiving the data is configured to read the data from an originating controller. An example of binding is configuring an outdoor air temperature sensor on one controller and referring all other devices on the network to it.

The data shared between various network devices is transmitted and received as network variables (NV). Within a device the network variable is identified as being an output (nvo) or input (nvi). A nvo transmits specific data from the device. A nvi receives specific data from the network for use by the device. In data sharing the source is a nvo and the destination is a nvi.

The LONMARK® Association defines Standard Network Variable Types (SNVT) for each registered profile. Manufacturers define additional network variables that are

specific to a given device. SNVTs are used to provide open communication between multiple manufacturers� devices. A manufacturer�s proprietary network variables are used to implement functionality beyond the profiles and to enhance device or system operation. LONSPEC�, RapidZone, and LonStat make no distinction between SNVTs and proprietary network variables. LonMark® SNVTs for each controller are shown in the Specification Data sheets for each controller. See Table 1 Applicable Literature for specific literature numbers.

In RapidZone and LonStat the applications are defined in the software tool and binding is done automatically and no user activity is required. While LONSPEC� also does much of the binding automatically, it is a more flexible tool supporting custom applications that may require the user to configure the binding in a configuration screen called �Refer Points�.

Each controller point available as a data source or destination is given a point name. The point name used in LONSPEC� �Refer Points� is not the user defined point name. The point names are consistent for all controllers of the same model but unique for each controller model. The point names are as shown in Tables 9 through 28.

The LONSPEC� configuration screen �Refer Points� sorts the available destination points based on the source point type. The sorting is based on the LonWorks® Standard Network Variable Type (SNVT) which may include many controller variables that are very different in function and not appropriate to share. In LONSPEC� each specific variable is identified by a unique name. For example the LonWorks® variable �SNVT_Temp_p� is used for outdoor air temperature, space temperature, discharge air temperature, effective setpoint, setpoint, and setpoint offset. In LONSPEC� each of these variable is given a unique name. However, in �Refer Points� when any one of the these variables is selected as the source point all of the variables of this type will be shown in the destination points list. It would be inappropriate to bind the outside air temperature to the setpoint. The user must ensure the binding meets the application requirements. Tables 9 through 28 show the relationship of the source and destination points.

In LCBS all network variables (points) exist for each controller even if not configured. Configuring the input tells the controller to expect data on the input and in Excel 10 controllers may enable specific control functions. It is possible to configure data sharing using points that are not configured. If an unconfigured point is used as a source point (nvo), no data will be sent and all receiving controllers will report it as an alarm. If the unconfigured point is a destination point, the data will be ignored by the controller. LONSPEC� does not check to determine if the points used have been configured.

Data Sharing for Control DevicesData sharing occurs in the configuration of the control devices (controllers) listed below. Supervisory devices such as Command Display, LONSTATION�, and LONSPEC� are not included in this discussion.

NOTE: Notation Convention: >> indicates a menu or field selection in a LONSPEC� configuration screen.

Refer Points ApplicationsIn general, data sharing with refer points is a simple process. In the Refer Points screen select the desired source controller and point and then select the desired destination controller(s) and point and add them to the Bound Points list. Appendix A provides tables listing all available source and destination points by controller type. The tables identify the appropriate pairings.

Time of Day SchedulingTime keeping and Time of Day (TOD) scheduling is done in the W7760A Building Manager and T7350H or T7300F/Q7300H Commercial Thermostat with communicating sub-base.

The W7760A has 7 schedules that can be assigned to the 6 Control Loops, 8 Start/Stop Loops, and 20 network objectsa

using the LONSPEC� Schedule Assign functionb. The T7350H has a single schedule that can be assigned to an unlimited number of objects. The T7300F/Q7300H has a single schedule that can be assigned to 4 network objects.

Each of the network objects assigned to a W7760A, T7350H, or T7300 schedule uses a network variable output (nvo) to send the Current State, Next, and Time Until Next Change of State (TUNCOS) across the LonWorks® bus to a corresponding network variable input (nvi). There are 20 nvo�s available from a W7760A, one from a T7350H, and 4 from a T7300. LONSPEC� binds the nvi to the respective nvo with no additional intervention by the user.

Using the LONSPEC� Schedule Assign function is the optimum method for scheduling XL10 controllers and W7760C Control Loops and Start/Stop Loops. However if the


41 74-3679�1

number of Schedule Assign(ments) are insufficient for an application, it is possible to bind additional objects to a W7760A, T7350H, or T7300F/ Q7300H using the LONSPEC� >>Network>>Refer Points function.

NOTE: This method extends the number of objects that can be scheduled from a controller but it does not expand the number of schedules available.

PROCESS:5. Determine the number of schedules required for the

objects to be scheduled. The total cannot exceed the number of schedules available from the source control-ler (8 for W7760A and one for T7350H and T7300A).

6. The source controller (W7760A and T7300F/Q7300H) and the destination controllers (objects) must beavailable in the LONSPEC� project. Best practicesdictates that the controllers be configured, especially the source controller schedules.

7. Use LONSPEC� Schedule Assign to assign eachschedule to be used to at least 1 object. It is necessary to review the T7350, T7300F/Q7300H, or W7760A Building Manager configuration for schedule assign-ment and manually record the schedule information for the object assigned and the number sequentially of the assignment (1 through 4 for T7300F/Q7300H and 1 through 20 for W7760A).

8. In the LONSPEC� Refer Points screen, select the desired schedule (T7350 Time of Day Out (TOD) [1], T7300F/Q7300H TOD Out [1-4], or W7760A TOD Event [1-20]) as the source point and refer it to the time of day input for the control device.

Outdoor Air ConditionsThe light commercial building system uses LonMark® standard network variable types (SNVT) to share the outdoor air temperature, humidity, enthalpy, and air quality from a

source controller to multiple controller requiring the data. It is necessary to use the LONSPEC� >> Network >> Refer Points to bind the source point (network variable output � nvo) to the destination points (network variable input � nvi).

To perform the Refer Points function, it is necessary that the controllers be available in the LONSPEC� project. Good engineering practice would dictate that the controllers be configured prior to referring points

The controller to which the outdoor air sensor is physically connected is the source controller and the input must be configured for the function. Configuring an Excel10 input automatically sets the appropriate network variable output for the controller. When configuring an W7760A Building Manager or W7760C Plant Manager, it is necessary to set the network variable type when configuring the analog input.

It is possible to have multiple source controllers for the same outside measurement (network variable). This can be desirable with a building or campus situated such that significant differences can exist for various measurements. For such configurations, the user must ensure the correct source controller is selected for the destination controller.

CAUTIONWhen using Refer Points, LONSPEC� does not check to verify that the source has been configured.The user must ensure the correct source and destination controllers and points are selected in the configuration process.

The following table provides by controller and outdoor air measurement the names of the network variables used in Refer Points.

Table 8. Outdoor Air Conditions Network Variable Names.

a While the nvi�s can be bound to the W7760A, they cannot be selected as an input for any control functions. For the W7760A it is necessary to select the source point as a remote (polled) point.

b The nvi�s are selectable as Input >> Remote >> Network >> nvoOdTemp or nvoOdHum.

BypassSharing the Bypass operation from one control device to another is done in the Refer Points screen. It is important to note that it is the bypass operation of the control device and not the wall module push button being shared. A number of factors determine the actual bypass status for a control device. Refer to the Application Guide for the specific controller for detailed information on the sequence of operation.

When the network bypass input is active, the bypass timer of the destination is not used and the destination controller will execute the bypass function as long as the source object is in bypass. When the source bypass goes inactive the destination bypass function will continue for 300 seconds. This permits multiple source objects to be referred (bound) to the same destination object and be read so that any one of the source objects being in bypass will cause the destination object to be in bypass.

To refer bypass in the Refer Points screen, select the source control device bypass output and the destination object bypass input and add to the Bound Points list. See the Refer Points tables in Appendix A for a complete list of source and destination points by controller type.

XL10 Free PointsThe Excel10 W7750A,B,C CVAHU, W7751B,D,F,H,J VAV II, and W7753 Unit Ventilator controllers may all be configured with network commandable digital output points called Free points. Generally these points are configured as remote points when configuring Excel 15 start-stop, control loops, or logic loops. However, they can also be controlled by binding them to an appropriate output from another Excel10 controller. For example, a switch might be wired to a digital input on a W7750 CVAHU controller configured as Monitor (source). This could then be referred to the Free 1 output on another controller (destination) wired to control lights. When the switch is activated on the source controller, the output on the destination controller would be activated turning on the lights. Any input of network output of NV type 95 can be used as the source for activating a Free point in Excel 10. It is the user�s responsibility to ensure the source is appropriate for the application.

Remote Point SelectionWhen configuring XL15A and XL15C control loops, start-stop loops, logic loops, and math functions, it is possible to select remote points (points from another control device on the network). The available points are automatically displayed when the remote function is selected in the configuration process. Appendix C provides a complete listing of the available points with a description of their function.

SrcHeatOutput Percentage of the heating stages on. (Stages On / Configured Stages X 100%)SrcHvacMode An output that may be used for coordinating system operating mode with other nodes. The current system mode

of the thermostat is reported in SrcHvacMode. This mode is determined either in the Q7300 (from network inputs) or in the thermostat (from front panel entries), whichever was changed last. Some thermostat models do not allow the system mode to be changed from the front panel. Not all operating modes are allowed in every thermostat model (i.e., a particular T7300 model may be heat-only, with no cooling allowed, etc.), and SrcHvacMode reflects the operating modes allowed in the thermostat model.
