The NET Concentrator®

SystemThis is the user’s manual for the Moore Industries NETConcentrator® System (NCS), a modular family thatprovides a link between dispersed field-mountedprocess monitoring/control equipment and the controlroom. The NCS transports just a few, or hundreds, ofprocess signals between the field or plant floor andyour control room on a single communicationsnetwork.

The NET Concentrator System is any combination ofone Interface Module with one or more I/O modules.If there are multiple Interface Modules on one network,the individual Interface Modules are termed stations,while all the combined modules are called a system.If there is a single Interface Module on a network, it(and any attached I/O modules) is termed a system.

The Interface Module and one or more I/O modulesconnect together via DB-25 connectors integrated into

the side(s) of each module. Any combination of inputand output modules may be used within a NET Con-centrator System network. Power for up to two input/output modules is supplied by the Interface Module. Atotal of eight units can be powered by adding a NETConcentrator System Power Module, or CPM.

About this ManualWherever you see a “Note”, “Caution”, or “WARNING ”pay particular attention.

• A “Note” provides information to help you avoidminor inconveniences during calibration,installation, or operation of the NCS.

• A “Caution” provides information on steps to take inavoiding procedures and practices that could riskdamage to the NCS or other equipment.

NCSMIM - TIMNET Concentrator® SystemTemperature Input Module

The TIM TemperatureInput ModuleThe Temperature Input Module (TIM) of the NCSfamily isolates and conditions up to four temperaturesignals and relays temperature information from theseinputs to the Interface Module.

Installing the TIMInstallation consists of physically mounting the unit,completing the input connections, and grounding theunit.

MountingThe TIM is designed to snap easily onto 32mm,G-type (EN50035) or 35mm Top Hat (EN50022) DIN-rails. Snap the TIM onto the DIN-rail to the right of theNCS module, then slide it along the rail until the DB25connectors on the side of the TIM connect completelywith the unit to its left. See Figure 8 for illustration.

Recommended Ground Wiring Practices

Input ConnectionsAfter mounting, you are ready to connect the inputs tothe TIM. Since the TIM receives power from theconnected Interface Module, only the temperaturesensor inputs need to be connected. Figure 8 showsthe connection diagrams for the TIM.

“Hot Swapable” I/O ModulesShould an Input/Output Module need to be replaced,simply program a new module, remove the oldmodule from the mounting base and snap in the newone. For more specific instructions, see AppendixC: Hot-Swapping a NET Concentrator Module.

CE ConformityInstallation of any Moore Industries’ product thatcarries the CE compliance marking (CommissionElectro technique) must adhere to their respectiveinstallation guidelines in order to meet the requirementsset forth in applicable EMC (ElectromagneticCompatibility) directive (EN61326). Consult the factoryfor additional information.

Moore Industries recommends the following groundwiring practices:

• Any Moore Industries product in a metalcase or housing should be grounded.

• The NCS individual module bases aremechanically grounded when installed ontothe DIN-rail. Be sure the DIN-rail isconnected to a system safety earth groundbefore making any other connections.

• All input signals to, and output signalsfrom, Moore Industries’ products should bewired using a shielded, twisted pairtechnique. Shields are to be connected to anearth or safety ground near the unit itself.

Settings

Filter-This setting is used to configure the inputfilter which is designed to reduce the effects ofmains-induced noise. The frequency value should beset to the frequency of the local AC supply.

Custom Curve-Checking this box allows you tosetup a custom linearization table of up to 128 pointsthat will tell the TIM what value to output when acertain input is received. This is accomplished byloading into memory a comma-separated value file(.csv) that was created in Excel® or a similar program.For instructions, refer to Appendix B: Loading aCustom Curve File.

Trimming-Select the “Trimming” box to enable.The TIM can be trimmed with an upper and lower trimpoint. When arriving at the Trimming screen, select “1Point Trim” or “2 Point Trim” in the Mode section.Next, in the “Trim Point” text box, place the value youwish to use. Depending on the parameter you aresetting, select the “Trim Lower” or “Trim Upper” boxand follow the instructions.

Ambient Temp-Check this box to compensate forthe effects of ambient temperature on thermocouplewire. To read ambient temperature, select °C or °Ffrom the dropdown menu, and then refer to theMODBUS Register Definitions table (Appendix A:MODBUS RTU Support, Table A-1).

Broken Wire Detection-Upon selection of thisfunction, the TIM performs continuous sensordiagnostics, monitoring the sensor and sending theoutput upscale or downscale during a failure.

Configuring the TIMThe TIM is configured using the PC ConfigurationProgram. To configure the TIM, you must first mountit to the Interface Module as described in Installing theTIM.

After mounting, bring up the NCS configurationsoftware. Add a TIM to the device tree. The TIMaccepts four different temperature inputs, and uses aseparate channel for each. Select the channel youwish to program. The screen shown in Figure 9 willappear. See below for a description of the differentparts of the screen.

UsageAllows you to select “Channel Not Used”. Checkingthis box will cause the TIM and its associatedInterface Module to ignore the selected channel,allowing you to use less than all four channels withoutreceiving error messages.

Input ConfigurationThis programs the type of input that the TIM willreceive. Different measurement types require differentparameters to be programmed. Once an input type isselected, the associated parameter fields will appear.When a measurement type is selected, otherparameters may become red, indicating that the redparameter must be programmed.

Input RangingAllows you to either input or capture the upper andlower ranges that you want to have measured.

Input ScalingInput Scaling allows you to take the input and convertit to a different range. For example, you take achannel with a 0-1000°C range and scale it to 0-100°C;now when the input is 734°C, it is relayed to theInterface Module as 73.4°C.

NCSMIM - AIMNET Concentrator® System

Analog Input Module

The AIM AnalogInput ModuleThe Analog Input Module (AIM) of the NCS family iso-lates and conditions four analog signals and relays in-put information to the Interface Module.

Installing the AIMInstallation consists of physically mounting the unit,completing the input connections, and grounding theunit.

MountingThe AIM is designed to snap easily onto 32mm,G-type (EN50035) or 35mm Top Hat (EN50022) DIN-rails. Snap the AIM onto the DIN-rail to the right of theNCS unit, then slide it along the rail until the DB25connectors on the side of the AIM connect completelywith the unit to its left. See Figure 11 for illustration.






Input ConnectionsAfter mounting, it is time to connect the analog inputsto the AIM. Since the AIM receives power from theconnected Interface Module, only the analog inputsneed to be connected. Figure 11 shows the connec-tion diagrams for an AIM.

“Hot Swapable” I/O ModulesShould an Input/Output Module need to be replaced,simply program a new module, remove the old modulefrom the mounting base and snap in the new one. Formore specific instructions, see Appendix C: Hot-Swap-ping a NET Concentrator Module.

CE ConformityInstallation of any Moore Industries’ product that car-ries the CE compliance marking (Commission Electrotechnique) must adhere to their respective installationguidelines in order to meet the requirements set forthin applicable EMC (Electromagnetic Compatibility)directive (EN61326). Consult the factory for additionalinformation.

Settings

Filter-This setting is used to configure the inputfilter which is designed to reduce the effects ofmains-induced noise. The frequency value should beset to the frequency of the local AC supply.

Custom Curve-Checking this box allows you tosetup a custom linearization table of up to 128 pointsthat will tell the AIM what value to output when acertain input is received. This is accomplished byloading into memory a comma-separated value file(.csv) that was created in Excel® or a similar program.For instructions, refer to Appendix B: Loading aCustom Curve File.

Trimming-Select the “Trimming” box to enable.The AIM can be trimmed with an upper and lower trimpoint. When arriving at the Trimming screen, select “1Point Trim” or “2 Point Trim” in the Mode section.Next, in the “Trim Point” text box, place the value youwish to use. Depending on the parameter you aresetting, select the “Trim Lower” or “Trim Upper” boxand follow the instructions.

Configuring the AIMThe AIM is configured using the PC ConfigurationProgram. To configure the AIM, you must first mountit to the Interface Module as described in Installing theAIM.

After mounting, bring up the NCS configurationsoftware. Add an AIM to the device tree. The AIMaccepts four different analog signals, and uses aseparate channel for each. Select the channel youwish to program. The screen shown in Figure 12 willappear. See below for a description of the differentparts of the screen.

UsageAllows you to select “Channel Not Used”. Checkingthis box will cause the AIM and its associatedInterface Module to ignore the selected channel,allowing you to use less than all four channels withoutreceiving error messages.

Input TypeThis sets the type of input that the AIM will receive.Different measurement types require differentparameters to be programmed. You may selectbetween “Volts” and “Current”. When a measurementtype is selected, other parameters may become red,indicating that the red parameter must be programmed.

Input RangingAllows you to either input or capture the upper andlower ranges that you want to have measured.

Input ScalingInput Scaling allows you to take the input and convertit to a different range. For example, you take achannel with a 0-10V range and scale it to 0-100V; nowwhen the input is 7.34V, it is relayed to the InterfaceModule as 73.4V.

NET Concentrator® SystemAnalog Output Module

The AOM AnalogOutput ModuleThe Analog Output Module (AOM) accepts informationfrom the NCS and outputs it as one of four indepen-dently configurable analog signals.

Installing the AOMInstallation consists of physically mounting the unit,completing the output connections, and grounding theunit.

MountingThe AOM is designed to snap easily onto 32mm,G-type (EN50035) or 35mm Top Hat (EN50022) DIN-rails. Snap the AOM onto the DIN-rail to the right ofthe NCS unit, then slide it along the rail until the DB25connectors on the side of the AOM connect com-pletely with the unit to its left. See Figure 14 forillustration.




• All input signals to, and output signalsfrom, Moore Industries’ products should bewired using a shielded, twisted pairtechnique. Shields are to be connected to anearth or safety ground at the unit itself.


Input and Output ConnectionsAfter mounting, it is time to connect the analogoutputs to the AOM. Since the AOM receives powerfrom the connected Interface Module, only the analogoutputs need to be connected. Figure 14 shows theconnection diagrams for an AOM.

Output on Out-of-Range PVThese boxes allow you to enter the value that you wantthe AOM’s output to return to (as a default) when themonitored input goes out of range.

Loop TestThis function allows you test the other instruments onthe loop by setting the AOM to output a specific value.After clicking Loop Test, use the arrows to select thedesired value and press Set to begin.

Output ScalingOutput scaling allows you to access the analog outputprocess variable in a number range more meaningful toyou than the acutal mA or Volts output. For example,if the actual output range is 4-20mA, set the scaledrange to 0-100; you now write “0” to the processvariable to get 4mA out and “100” to get 20mA out.

Output on FailureThis section tells the AOM what to do when themonitored input fails entirely. It will either maintain thelast value (Hold Last), or jump to a predefined valuethat you input (Preset Predefined Value).

Settings

Trimming-The AOM can be trimmed with two datapoints within the selected zero and span output range.This allows a complete range to be output, whileplacing an emphasis on a specific segment of therange most critical to the process.

Output Damping-Allows you to introduce a delayinto the AOM’s response to a change in input. Thevalue of the output damping is the number of secondsthat it will take for a display to make a 63% change inresponse to the chane in input. A damping of “0” willdisable damping.

Configuring the AOMThe AOM is configured using the PC ConfigurationProgram. To configure the AOM, you must first mountit to the Interface Module as described in Installing theAOM.

After mounting, bring up the NCS configurationsoftware. Add a AOM to the device tree. The AOMoutputs four different analog signals, and uses aseparate channel for each.

NCSMIM – DIM


NET Concentrator® SystemDiscrete Input Module

The DIM DiscreteInput ModuleThe Discrete Input Module (DIM) of the NCS familyisolates and conditions up to eight discrete signals,and relays input information to the Interface Module.The DIM is available for three different discrete inputchannel types: contact closure, high range voltage, orlow range voltage. See the NCS Data Sheet for moreinformation on module types and options.

Installing the DIMInstallation consists of physically mounting the unit,completing the input connections, and grounding theunit.

MountingThe DIM is designed to snap easily onto 32mm,G-type (EN50035) or 35mm Top Hat (EN50022) DIN-rails. Snap the DIM onto the DIN-rail to the right of theNCS unit, then slide it along the rail until the DB25connectors on the side of the DIM connect completelywith the unit to its left. See Figure 18 for illustration.






Input ConnectionsAfter mounting, it is time to connect the discrete in-puts to the DIM. Since the DIM receives power fromthe connected Interface Module, only the discrete in-puts need to be connected. Figure 18 shows the con-nection diagrams for the DIM.

NCSMIM – DIM



Configuring the DIMThe DIM is configured using the PC Configuration Pro-gram. To configure the DIM, you must first mount it tothe Interface Module as described in Installing theDIM.

After mounting, bring up the NCS configuration soft-ware. Add your DIM to the device tree. See below fora description of the different parts of the screen.

DIM Discrete Contact Closure Input Module(DIMCC)With the DIM Discrete Contact Closure Input Module(DIMCC) the only configurable parameter is debouncetime. Once you have accessed the NCS configurationsoftware, select the DIM (CC8) module in the devicetree. This will display the screen shown in Figure 20.

Settings

Contact Debounce-When some contacts open orclose, there can be a short period of oscillation result-ing from the mechanical contacts. The ContactDebounce setting causes the NCS to ignore false sig-nals caused by these oscillations. This setting is onlyavailable with contact closure DIM (DIMCC) modules.

DIM Discrete Voltage Input Module (DIMV)There are no configurable parameters within the DIMV.Its configuration is hard-wired. Once the module isadded to the device tree and its configuration up-loaded, it is brought into the system. A heading in thedevice tree identifies whether the DIMV is a Low orHigh Range unit. Figure 21 displays the screen thatwill appear once the unit is introduced into the system.

Appendix A: MODBUS RTUSupportEach NCS Interface Module is designed to beaccessed using either a supplied OPC server orMODBUS communication. Directions for connectingto the OPC server can be found in the installation sec-tion for your Interface Module. The section below sup-plies all of the information necessary to reference theMODBUS register map and program a genericMODBUS RTU OPC server, or other MODBUS RTUmaster.

The MIM acts as independent MODBUS RTU slave oneach of the two RS-485 ports. The MODBUS registersallow access to process variable data and status infor-mation. See Table A-1 for a complete list of availableMODBUS Registers.

Reading Primary VariablesProcess variables are read using MODBUS functioncode 3 or 4. Each 32-bit floating-point process vari-able will be mapped to two MODBUS registers; thelower numbered MODBUS register will hold the least-significant-word (LSW), and the higher numberedMODBUS register will hold the most-significant-word

(MSW) of the 32-bit value. For MODBUS masters thatuse swapped floating point, the MIM has a configura-tion setting to change the default word order which is(LSW).

Reading Device StatusDiagnostic data is read using MODBUS function codes1 to 4. Each 16-bit status register will be oneMODBUS integer register, accessible using functioncodes 3 or 4. When using function codes 1 or 2, the16 status register bits are mapped to 16 consecutivecells, with the status register’s least-significant-bit inthe lowest addressed cell.

Communicating with NET Concentrator ModulesAt startup, the Interface Module will perform an initial-ization sequence to detect all connected NCS I/Omodules. If it recognizes the connected device, it willmark the module as active in preparation for datascanning.

After detecting connected NCS modules, the InterfaceModule will begin continuous polling for the currentprocess variable and status of each module. Thereturned data is stored locally by the Inteface Modulefor access by the configuration software,MODBUS RTU master or OPC server.

Appendix B: Loading aCustom Curve FileThere are two ways in which a custom curve can beloaded into the MIM for use with the TIM or AIMconfiguration pages. In order to create a CommaSeparated Value (.csv) file, you will need eitherMicrosoft Excel® or other similar spreadsheet program,or a text editor.

To configure the TIM or AIM with the custom curve,perform the following:

1. In the Settings section of the configuration page forthe channel requiring the custom curve, check the“Trimming” box.

2. Next, in the device tree, click the channel of theassociated module in order to expose the customcurve parameter .

3. The window in Figure A-1 (below) will appear.

4. In the Number of Linearization Points box, type thenumber of points you are to use, then hit “Enter”.

Using a spreadsheet programIn Microsoft Excel®, open a new sheet (refer to FigureA-2). Using column A as your X data, and column Bas your Y data observe the following scheme:

Column A: The X data must be a monotonicallyincreasing sequence (i.e, each value must be greaterthan the previous value in the sequence).

Column B: The Y data may be any sequence. Youmay enter up to 128 X,Y pairs. All numbers must bereal, signed numbers, up to 6 digits long (7 digits andhigher must be translated to exponential notation) or 6plus one decimal point. Exponent notation (in the formof 1e+010, rather than 10e9) may also be used, but itwill be translated to the full value (i.e. 10e9 =10000000000) and thus must not represent a numberhigher than Xe37. Numbers represented as Xe38 andabove will produce errors.

After entering your values, simply save as a .csv file.

Using a text editorObserving the same rules as above, you can also usea text editor, as shown in Figure A-3, to create your.csv file.

Saving and Opening FilesThe files must be saved with a .csv extention. Whenyou are ready to save your file, simply right-click thecustom curve parameter that you are working on in thedevice tree and select “Export” to save to yourdesignated location.

To open a saved file, right-click the desired customcurve parameter in the the device tree and select“Import”.

Appendix C:Hot-Swapping a NETConcentrator® ModuleShould an Input/Output Module need to be replaced,you do not need to power down the NET ConcentratorSystem. Instead, simply remove the old module fromthe terminal base, and snap in the new one.

Programming a New ModuleThe NCS uses the configuration present in the newmodule. If the new module has the same configurationas the one being replaced, nothing else needs to bedone. If not, the new module must be programmedusing the directions in the configuration section of themanual that applies to the module being installed.

Removing the Old ModuleBegin by taking two small flathead screwdrivers andinsert each under a different base clip, as shown inFigure A-4. With the base clips pulled away, pull themodule out from the base.

Snapping in the New ModuleCheck to see that the keying post (shown in FigureA-5) will line up properly with the keying hole in thebottom of the module. If it does not, rotate the module180°. If it still does not line up, the module is of thewrong I/O type. The new module must be of the sametype as the previous module.

Caution:Do not try to force to force in the unit. You will

damage the module.

Slip the new module into the base that the old one wasremoved from. Push firmly into position. The lightson the face of the input/output module should glow asthe unit powers up.

Highlight the Interface Module in the device tree. Inthe Communciations dropdown menu, select “Synchro-nize” to update such details as firmware revision andmodule serial number.

Note:A new NCS module will only work with an identical

type of base. For example, you cannot place an AIMmodule into a base that previously held a TIM; the new

module must replace an identical older module.

Appendix D: MODBUS Integer Access

Register AddressingThe data in each NCS interface module is designed to be accessed using either an OPC server or MODBUS communication. The section below supplies all of the information necessary to reference the MODBUS register map for 16-bit unsigned Integer values. The fl oating point reference map is located in Appendix A of the User’s Manual.

There are two register ranges containing the scaled 16-bit integer equivalents for the fl oating point data. Primary variables are in the fi rst set at an offset of 600. Ambient temperatures are in the second set at an offset of 700.

288-766-01B

Primary Variables The primary variable data in each NCS I/O module occupies four consecutive integer registers. Data in module 1 occupies registers 601 through 604. Module 2 occupies registers 605 through 608. See Table A-7 for mapping reference. Regardless of the I/O data type, fl oating point or discrete, an I/O module occupies its four alotted integer registers. Note if the I/O module is of discrete data type– DIM or ROM– the contents of the four integer registers it occupies contain nothing.

Note:Refer to Table A-1 for discrete I/O module mapping.

Ambient TemperatureA range of integer registers starting at 701 contains the ambient temperature variables for the TIM (Temperature Input Module). Four consecutive registers are dedicated to each module position, regardless of whether the module is a TIM. If there is a TIM in position 2, its four integer scaled ambient temperature variables will appear at registers 705, 706, 707 and 708.

with MODBUS InterfaceMODBUS Integer Access


OverviewTo support MODBUS Masters which prefer reading and processing variables as integers, each PV is also accessible as a 16 bit integer. For input modules, the NCS Interface Module will convert the fl oating point input value to an integer. This value can then be read and used by the MODBUS Master. For output modules, the MODBUS master will generate the scaled integer, and write it to the NCS Interface Module. The NCS will convert this value to fl oating point, and will use it to drive the output.

Default Integer Scaling BehaviorMIM Firmware Versions prior to 3.12 only support the standard Integer Scaling, hereafter described as the “Default Scaling Behavior.” Default behavior is to scale the PV value between the Input/Output Range (or Scaled Range if Scaling is enabled in a channel) and the Integer Range of 4096 (0x1000) to 61440 (0xF000) as per Table A-8. If a DCS does not support this integer range (for example if they are limited to integers between 0 and 9999), then “User Defi ned Integer Scaling” should be used.

Table A-8. Integer values used in the data conversion and their default values (prior to Firmware Version 3.12)

Table A-10. TIM ambient variables (fi xed).

Table A-9. Settings used for the Float Zero and Float Full values.

Value Name Default Value

Scaled Integer Zero 4096 (0x1000)Scaled Integer Full 61440 (0xF000)Scaled Integer Zero Limit 0 (0x0000)

Scaled Integer Full Limit 65535 (0xFFFF)

User Defi ned Integer ScalingMIM Firmware Versions 3.12 and later provide for User Defi ned Integer Scaling. This allows the user to perform a system wide override of the values used in the conversion to and from Scaled Integer values. The purpose of this is to accommodate MODBUS Register formats required by existing DCS and PLCs.

On the Confi guration page of the NCS Confi guration Software, check the “User Defi ned Integer Scaling” check box. This activates the “User Defi ned Integer Scaling” and deactivates the “Default Integer Scaling”. Then enter the Zero, Full and Limits to be used in the calculation.

Data ConversionInteger data is unsigned. The Float Zero (input/output lower range) value is mapped to Scaled Integer Zero, and the Float Full (input / output upper range value) is mapped to Scaled Integer Full. This range allows an integer representation of the entire range with some additional room for out-of-range values. For process variables the Float Zero and Float Full values are taken from the Lower Range Value and the Upper Range Value unless scaling is enabled. If scaling is enabled, they are taken from the Lower and Upper Scaled Values. As the variable goes out of range, it is limited by the Scaled Integer Zero or Full Limit. This is summarized in Table A-9.

Value Name

Zero Float Input Zero Output Zero Scaling Zero

Float Full Input Full Output Full Scaling Full

Input Module,Scaling Disabled

Output Module,Scaling Disabled

Input or Output Module, Scaling Enabled

Value Name Value

Float Zero -40°C

Float Full 85°C

For ambient temperature variables in the TIM, the ambient operating range is used for the Float Zero and Full. Thus Float Zero is -40°C, and Float Full is 85°C. The Float Zero and Float Full values are fi xed and therefore they cannot be sub-ranged per Table A-10.

Upon accessing the Scaled Integer corresponding to this input channel, the user observes a value of 16862 (0x41DE.) The following calculation is performed to convert this value to Floating point:

The scaled integer value of 16862 (0x41DE) equals 80.862 degrees Fahrenheit

Output Confi guration : Current Output Range: 4 to 20 mA User Defi ned Integer Scaling: Disabled

The user wishes to set the output current to 12.34 mA. The following calculation is performed to determine what value to write to the scaled integer register:

Scaled Int PV= (FloatPV-Float Zero) +4096( )57344FloatFull-FloatZero

Scaled Int PV= 33987 (0x84C3)

Scaled Int PV= (12.34-4.0) +4096( )5734420.0 - 4.0

To obtain an output of 12.34 mA, a value of 33987 (0x84C3) should be written to the Channel’s Scaled Integer register.

Example #2: This example illustrates converting the Floating Point value to an integer value with a single fi xed decimal point. This makes it easy to look at the Scaled Integer, and interpret it with no fancy calculations (i.e. just shift the decimal point to the left one position.) It also shows the resulting Scaled Integers if default behavior is used.

The input signal to a NCS TIM channel is a resistance with typical PV (Process Variable) values from 250 Ohms to 750 Ohms. It is desirable to also report the values below the expected 250 Ohms and above 750 Ohms.

with MODBUS InterfacePeer-to-Peer Configuration

October 2004


The following information supersedes data in the NCSMIM

NET Concentrator® System with MODBUS InterfaceModule User’s Manual, 288-766-00, Revision A.

The information contained in this document describesthe operation and use of the Peer-to-Peer function of theNCSMIM.

Peer-to-Peer systems function without the use of a hostdevice and continuously communicate the inputs and/oroutputs of field instrumentation from point-to-point over adigital data communications link.

Among the features available with the NCSMIM is the abil-ity to map temperature inputs of one station to the ana-log outputs of another. You are also able to map theinputs of one station to the outputs of a second all whilemapping inputs of the second station to the outputs ofthe first. Point-to-multipoint mapping is also available inwhich you are able to map the inputs of one station tothe outputs of multiple other stations.

MIM System ConfigurationsThe MIM has two independent MODBUS communicationports that support different network architectures. Asystem of MIM stations can communicate in one of thefollowing three configurations:

1. As a system of MODBUS slaves with two indepen-dent communication ports for each MIM (this has beendescribed in the NCSMIM User’s Manual).

2. As a Peer-to-Peer system on one MODBUS port andas a system of MODBUS slaves on a second port.

3. As a Peer-to-Peer system with redundant communi-cation ports.

System TerminologyTo fully understand the MIM Peer-to-Peer system and itsconfiguration, certain terms must be understood. Thefollowing are explanations of terms used in the system.

288-766-02A© 2004 Moore Industries-International, Inc.

Producer and ConsumerIn a Peer-to-Peer system, the MIM whose inputs aremapped to another MIM’s outputs is called a Producer.The MIM that reads the inputs from another MIM andmaps them to its own outputs is called a Consumer. Forexample, if an MIM-AIM system is connected via a Peer-to-Peer network to a MIM-AOM, the MIM-AIM system willbe a producer and the MIM-AOM system will be aconsumer. There are several valid producer and con-sumer relationships in a system including:

A. A station may be solely a Producer (because it hasonly inputs).

B. A station may be solely a Consumer (because it hasonly outputs).

C. A station may be both a consumer of anotherstation’s inputs, as well as a producer supplying data foroutputs of consumer stations.

In essence, the producer is the station generating inputsignals; the consumer station receives and processesthose inputs to produce output signals.

Software ConfigurationThe MIM has two MODBUS ports that are independentlyconfigurable. For each MODBUS port, there are four re-quired software configuration parameters for Peer-to-Peerconfiguration: Mode, MODBUS Address, Consumer andProducer’s MODBUS Address.

Mode determines whether the MODBUS port is in Peer-to-Peer or MODBUS slave mode. If, for example, a sys-tem of MIM stations is to operate as a Peer-to-Peersystem on MODBUS Port 1, then you must ensure Peer-to-Peer mode is enabled on MODBUS Port 1 in all MIMsin the system. You must also ensure that baud rate,parity, character timeout and response delay are thesame in all MIMs in that system.

Each port may be individually configured for either nor-mal MODBUS slave operation or for Peer-to-Peer opera-tion. You must set the Mode to the same value in allMIM stations of the Peer-to-Peer system.

The MODBUS Address can be set independently foreach port. The allowed range for a MODBUS slave is 1to 247. However, the allowed range in Peer-to-Peermode is 1-32. The user is responsible for assigningeach MIM station in a given network with a uniqueMODBUS Address. If both ports of the MIM are beingused on the same bus, the ports must have unique ad-dresses.




Examples of Peer-to-PeerConfigurationsTo help describe the various capabilities of the Peer-to-Peer system, written and illustrated examples of particu-lar configurations are detailed below.

Single Station Pair ConfigurationsA Peer-to-Peer system configuration is described in thefollowing application example.

You have two MIM stations communicating Peer-to-Peer (bi-directional) on Port 1. On Port 2, thesesame MIMs will communicate with a MODBUSMaster in a Peer-to-Host configuration.

Figure S-2 provides an illustrated representation of thisexample with the AIM in position 1 of the producermapping to the AOM in position 1 of the consumer andtheir channels mapping from channels 1 to 1, 2 to 2 andso forth. Refer to Figure S-1 for an example of PCsoftware window configuration.

Note:Only modules of like data types can map to each other(analog data AIMs and TIMs map to AOMs; discrete

data DIMs map to ROMs).

You may access diagnostics information in theconsumer for the application in the example above via

the NCS Configuration Software program.

Enabling Peer-to-Peer SoftwareConfigurationTo configure a Peer-to-Peer network, you must use NCSConfiguration Software Program (NCS Config), version3.04 or later.

Note:For further clarification of terms or parameters inthe NCS Configuration Software Program, right-click the related portion of the screen and select

the “What’s This?” button.

Connect each MIM as detailed in the PC ConfigurationProgram section of the NCSMIM User’s Manual. Toenable the Peer-to-Peer feature in the MODBUS configu-ration window, check the “Enable Peer to Peer Mode”box for either MODBUS 1, MODBUS 2 or both ports forredundant Peer-to-Peer. Perform this for all MIMs inyour system that require operation in Peer-to-Peer mode.

To connect multiple MIMs with a limited number ofavailable COM Ports, connect and configure each MIM

Each MODBUS port can be individually configured toenable the MIM station to act as a Peer-to-Peer modeconsumer on that port. For all consumer station ports, aProducer’s MODBUS Address (see below) must be as-signed. When the consumer feature is disabled, noProducer’s MODBUS Address is assigned and thestation’s output channels will have no input (from anotherMIM station) mapped to them via that port.

The Producer’s MODBUS Address identifies theMODBUS address of the MIM station containing the in-put channels that will be mapped to the output channelsof this station. The address range is 1-32 excluding theMODBUS Address of the station being configured.

Hardware ConfigurationThe MIM with the Peer-to-Peer feature has a point-to-point or point-to-multipoint relationship. In each case,however, the module must be in the same position as themodule with which it is exchanging data. For example, ifthe Producer station has a MIM-TIM-AIM-DIM configura-tion, then the Consumer station must have a MIM-AOM-AOM-ROM configuration. If the discrete and analogmodule positions are not the same in the producer andconsumer, an incompatible module fault will occur (seeTable S-1).

individually on the accessible port then disconnect andmove to the next MIM. Repeat this for all MIMs in yoursystem.

Once you enable Peer-to-Peer, the “Consumer” boxbecomes available. If your station is to also be config-ured as a consumer, check this box.

When enabling your MIM as a consumer, you must enteran address value in the “Producer’s MODBUS Address”text box. This number may be any value between 1 and32, with the exception of the value entered into the“MODBUS Address” box in the configuration window.

Ensure that all MIM baud rates, parities, charactertimeouts and response delays match one another.

Repeat the previous steps for all MIMs in your systemthat are to be configured as Peer-to-Peer.

Multiple Station ConfigurationsA typical application when using multiple stations withredundant Peer-to-Peer and using point-to-multipointmapping is outlined below. Refer to Figure S-4 for anillustrated representation of this example. Refer toFigure S-3 for an example of PC software windowconfiguration.

Map four temperature inputs from Station 1 to fouranalog outputs (4-20mA) of Stations 2, 3 and 4.

Note:Analog output channels must be configured to scale

the producer temperature data to the current or voltageoutputs (refer to Figure S-5 for an example).

Access diagnostics through MODBUS by interruptingPeer-to-Peer communications on either port network.For the consumer only, you may use the NCS Configura-tion Software program to view diagnostics messages.

Viewing Peer-to-Peer Faultsvia MODBUSThe Peer-to-Peer Status Register can be accessed viaMODBUS on the second port if the first is declared Peer-to-Peer, or on the Peer-to-Peer link itself. A MODBUSmaster on a Peer-to-Peer link may interrupt the Peer-to-Peer communications on that link and poll any slave fordiagnostics, or any other data. When the MODBUSmaster goes silent, Peer-to-Peer communications willresume. The 16-Bit “Peer-to-Peer Status Register” maybe read using MODBUS analog commands 3 and 4. Theindividual flag bits within the register are also availablethrough discrete read commands 1 and 2 where “B” is thebit position within the Peer-to-Peer Status register (seetable below). The bit positions and corresponding faultsare outlined in Table S-1.

Fault ConditionsIf any of the faults listed in Table S-1 are present,meaning data is not available to drive the output, theoutput channel behaves according to the “Output OnFailure” parameter(s) in the output channel configuration.See Figure S-5 for an example of output channel configu-ration.

DiagnosticsFaults preventing correct process data from reaching aconsumer station, or “Peer-to-Peer faults”, will beflagged and made available in the consumer station MIMfor you to access via MODBUS or the NCS PC Configu-ration Software program. In addition, the Status LED ofthe consumer MIM station will turn red. Refer to TableS-1 for descriptions of these faults and their causes.

Loss of Port 1 on a RedundantPeer-to-Peer SystemWhen the communication link to Port 1 is severed,Peer-to-Peer communications will automatically switchto Port 2, the redundant port. When this happens, thestatus LED on the consumer(s) will turn red and theappropriate MODBUS status bits in Table S-1 will beactivated to true. This Port 1 communication failure canalso be seen when using the NCS Configuration Soft-ware in the “Monitor Process Data” view. Once thesevered link for Port 1 has been repaired, the Peer-to-Peer communication link will switch back to Port 1 andthe LED will return to green with the status bits resettingback to false.

Note:Peer-to-Peer will automatically switch to Port 2 ONLYwhen Port 2 is configured for Peer-to-Peer AND the

RS-485 bus is healthy.

Display of Peer-to-Peer Faults in NCSPC Configuration Software ProgramPeer-to-Peer faults on a given station can be viewedthrough the PC Configuration Software program on theProcess Data page of the consumer station, the samepage where MIM and system level faults are listed.Descriptions of all present faults are shown simulta-neously.
