Modular design for universal application

With its modular design, Desigo PX can be adapted to specific requirements and needs, making cost-effective DDC technology a possibility even in small HVAC systems. Investment costs are limited to those system components that are actually needed. This innovative approach allows phased expansion of Desigo PX into a building automation and control system as and when required.

BACnet communications for maximum openness

Desigo PX sets new standards in relation to present and future communications technologies. The use of BACnet /LonTalk or BACnet/IP underlines the openness of our systems and our utilization of the latest communications technologies. BACnet opens up the system, to allow easy integration of systems and compo-nents from third-party manufacturers.

Made-to-measure operator units

The various operator units in the Desigo PX range more than satisfy all the various requirements in terms of location and function.

The plant can be monitored and operated from a Web client via a Web controller. In the event of a fault, the Web controller transmits SMS messages and allows remote diagnostics via Web client.

The PXM10 and PXM20 operator units, which can be optimized for different categories of user (e.g. resident engineer), offer users an easy means of checking the operation of the building services plant or of modifying the comprehensive time schedules to take account of changes in occupancy.

Room units optimized for building occupants can be used for simple and direct local operation of the plant. In this way, the room temperature in a conference room, for example, can be easily adapted to individual needs.

A family of programmable automation stations

With the PXC… family of programmable automation stations, Desigo PX offers maximum flexibility in the control and monitoring of building services systems. Comprehensive system functions such as alarm management, time scheduling and trend data storage cover all the requirements associated with the operation of a building. The distributed automation stations, available in two categories, operate autonomously. Communication is via the open BACnet protocol.

Professional software tools are available for engineering and other processing of the automation stations.

The starting point for the engineering of the program functions is the range of user-friendly application blocks and function blocks in the new programming language D-MAP (Desigo Modular Application Programming). D-MAP is optimized for building services applications and is based on the IEC 1131 standard. The graphical user interface of the software tools ensures an efficient approach.

Scope for phased expansion

The Desigo PX automation system can be expanded step by step into a full building automation and control system.

The Desigo Insight management station offers convenient multi-user operation system wide. It can be connected to Desigo PX via Ethernet/IP, LonTalk / LONWORKS or by modem.

Desigo RXC room controllers can be integrated seamlessly into the automation level via the system controllers.

Third-party subsystems, such as fire detection systems, intruder protection, lighting or refrigeration plant, can be integrated simply and cost-effectively into Desigo PX.

All parts of the plant can be interconnected via router and Ethernet/IP LAN. The automation stations also communicate directly on Ethernet/IP, allowing cost-effective use of the existing IT infrastructure for Desigo PX.

Monitoring, operation and display Alarm management

An important factor for the efficient operation of plant is the alarm management system, which ensures early identification of problems in the plant and initiates automatic strategies to help prevent any resulting damage.

General alarm mechanisms

Desigo PX is based on the BACnet standard. With three types of alarm, Simple, Basic and Extended, the method of handling and acknowledging alarms can be matched to the plant technology. The alarm message is accompanied by vital information which helps the building occupant to locate the cause of the fault.

• Additional information in text form is automatically added to the alarm message. • Alarms are identified with a date and time stamp. • Technical staff can see exactly where the alarm originated – in which plant,

which aggregate and which component.

Automatic information for the plant operator:

Many building services installations are not continuously monitored by technical staff. This is why Desigo PX automatically transmits alarm messages to a predefined address.

Overview of plant faults

The plant operator can use the Alarm Viewer function to display all active alarms and their current status.

Alarm Viewer in PXM20 Alarm Viewer via PX-WEB Web operation

Alarm functions

The standard "Simple" alarm triggers certain reactions in the automation station, e.g. equipment is switched off, valves are opened, etc. At the same time, the alarm message is transferred to the specified target operator units and output devices. There is no need for the alarm to be acknowledged by the customer; however, the display or the pop-up window of the operator unit can be deleted.

"Basic" alarms are used for important alarms which require the operator to check the cause manually. When an alarm occurs, the automation station triggers the appropriate reactions, such as automatic switch-off, opening of valves, etc. The alarm message is simultaneously saved and transmitted to display units such as local operator units or management stations, as defined in the alarm distribution system. The alarm must be acknowledged.

The "Extended" alarms, for safety functions, are an expansion of the basic alarm function. With these alarms, the operator must not only acknowledge the incoming alarm but also, after checking the cause of the alarm and clearing the fault, reset the alarm to return the plant to normal operation.

This alarm mechanism offers double security and is especially suitable for safety-critical plant.

Safety aspects

To avoid the loss of alarms in transit, all transmitted alarms are monitored for transfer and receipt. Any information about faulty transmissions is saved.

Alarm visualization

When an alarm is displayed, the user can see the relevant information at a glance. The display format is uniform throughout the system.

Displaying the plant status

The building operator can obtain an overview of the status of the building services plant at any time, in order to initiate any necessary actions. The overview includes the most important current values, plant status and setpoints.

For a quick and simple overview, the building operator can quickly identify the current values in the building services plant from the list of the most important values, and can then initiate the required actions, based on the plant status displayed (e.g. OFF). Alternatively, the building operator can obtain the required information displayed directly in a plant graphic page, via a standard Web client and customer-specific or plant-specific overviews. These graphics-based over-views can also be easily created or customized by the operator.

Monitoring the plant with trend functions

To check the dynamic response of the building services plant, trend functions are provided which the user can set up as required, to monitor critical equipment or to log relevant data for further processing.

To do this, the user simply defines which data points are to be monitored and how frequently. The trend functions can also be combined with other system functions. Trend logging can be stopped, for example, at a predefined time or when an alarm event occurs. The logged data is available for analysis at a later date.

With the PXM20, the user has a simple means of logging up to five data series and displaying them, two at a time, in graph form.

Trend data can be transferred to Desigo Insight.

Checking the dynamic response of the plant using the PXM20

Global data

Every automation station contains all the data necessary for stand-alone operation. The same applies to shared data such as date/time or calendar information which is identical for several or all automation stations.

To avoid having to update changes in parameter settings separately in each automation station, the shared data is treated as "global data" and handled centrally.

Scheduler/Calendar

The time control of procedures and processes is one of the daily basic functions of a building automation and control system. Ventilation, heating, air conditioning, lighting, door locks etc, are controlled on the basis of opening times and working hours in buildings such as offices, banks, restaurants, department stores and schools.

Scheduler programs ensure that lights are switched off automatically at the end of the working day, and that the temperature setpoint in the building is reduced at night. These schedulers can also be used to ensure that offices are not air-conditioned during public and works holidays, and that plant is not kept running for longer than necessary.

All scheduler programs are directly saved and processed locally at the automation level. Thus full synchronization of individual processes is ensured at all times.

10 / 30


Optimum scheduling helps save energy and extend the life of the plant.

In practice, building operators do not exploit this potential to the full, because the time scheduling in their systems is too complex and lacking in clarity. The Desigo operator units display ergonomically designed time schedules which are easy to use.

7-day program on the PXM20 Calendar on the PXM20

7-day programs (for each switching routine)

• Time-switching profiles over seven days. • Ten switching operations possible per day possible (1-minute resolution).

• Three different output signals

digital (on/off); multi-state (e.g. off - stage I - stage II), analog (e.g. 21 °C).

Exception programs

• Date, exception and holiday programs to override the 7-day program • A maximum of 20 exception profiles, each consisting of 10 switch times • Entry of special recurrent exception programs, Example: for a shopping center

which remains open until 2000 hours every 3rd Saturday in the month. • Overview of all plant parts controlled by this 7-day program.

Calendar

• Display of dates for control of exception profiles. The scheduler programs and calendar are based on the BACnet standard.

11 / 30


Data access rights

Access rights provide the convenience of filtering information according to the individual user requirements. This means, for example, that the resident engineer or service engineer only has access to the information actually needed to do the job. A distinction can also be made between read access and write access. Certain users may be able to read a value but not modify it, while other users may have extended access rights, enabling them both to read and to modify values. Information to which a user has no access is not displayed to that user on the PXM20 operator unit.

Access levels

Within the system there are four basic categories of access, ideally matched to individual user groups. The more experienced the users, the greater the amount of information to which they have read and write access. These access rights can, however, be modified at any time to suit a specific project. Up to seven access levels can be defined.

The basic rule is that users with a given access level have access to all values at their own level and at all access levels below their own.

Remote management

The Desigo system allows the remote management of building services plant, both from a Web client and with the Desigo Insight management station.

The following functions are supported:

• Remote fault and maintenance alarms • Remote monitoring and operation of all plant • Overview and modification of 7-day programs, calendars and setpoints • Modification of operating parameters

Operation at the automation level PXM20 network operator units

The PXM20 and PXM20-E network-compatible operator units allows full operation of all Desigo PX automation stations connected to a BACnet network. As a BACnet client, the PXM20/20-E automatically reads the data from the Desigo PX automation stations. It is therefore always up to date and can be replaced while the system is in operation.

The operator unit has a high-resolution illuminated display for graphics and text, keys for operation, and a common alarm indicator with an audible signal. The operator unit can be mounted remotely for compact and modular automation stations in the control panel door.

The clearly arranged function buttons and fast access buttons ensure correct operation, even by inexperienced users.

Programming with D-MAP

The D-MAP programming language (Desigo Modular Application Programming) for Desigo PX ensures efficient programming and parameter setting for building services plant. D-MAP is optimized for building services applications. The control strategies required for and best suited to efficient operation are implemented using graphics-based data flow programming.

Efficient engineering with blocks and compounds

The project-specific HVAC applications are configured, programmed, commissio-ned and maintained using the CFC Editor. The CFC Editor is a graphics editor based on block and data flow techniques. Predefined and tested application programs are assembled to create compound structures (referred to simply as “compounds”), and these are then made available in the libraries.

Creating the CFC chart with the CFC Editor • The basic elements of D-MAP programming are blocks and "compounds"

(compound functional units). These are stored in libraries. • To create a D-MAP program, the blocks and compounds for the required

functions are put together in the CFC Editor. This process involves creating instances (of blocks) or copies (of compounds) from the libraries

• The flow of data between blocks is programmed by interconnecting the "pins" (inputs and outputs) of various blocks
