1 Application Description 1.1 Objective This document describes an application using Allen-Bradley ControlLogix PLC with MGate 5105-MB-EIP. In this application, Allen-Bradley ControlLogix PLC is used to get input data that MGate 5105-MB-EIP polls from the temperature meter through Modbus Register. Allen-Bradley ControlLogix PLC evaluates the temperature value and outputs data to MGate 5105-MB-EIP, which then uses the data to control speed. 1.2 Goals In this document, you will learn the following: 1. Configure Allen-Bradley ControlLogix PLC. 2. Configure MGate 5105-MB-EIP to communicate with a Modbus RTU device. 3. Set up MGate 5105-MB-EIP in RSLogix 5000. 4. Create a basic RSLogix Ladder Programming. 5. Industrial field applications and the job of each role. 2 System Topology The following figure shows a system architecture in which the Modbus end devices, PowerFlex 4M and IAQPoint2, are connected to the serial port on MGate 5105-MB-EIP through RS-485-2W wiring. MGate 5105-MB-EIP and PC (running RSLogix 5000) are connected to Ethernet switch ports on Allen-Bradley ControlLogix PLC. A fan is connected to PowerFlex 4M, which powers the fan.

6 RSLogix Ladder Programming 6.1 Adding a Subroutine 1. In the Controller Organizer tree menu, click Tasks > MainTask. Then, right-click MainProgram and select New Routine. 2. In the New Routine screen, enter Init in the Name field and click OK. Copyright 2014 Moxa Inc. Page 26 of 36
6.2 Editing a Subroutine 1. Click the Init subroutine under Tasks > MainTask. 2. Drag a NEQ instruction to Rung 0; then, set input Source A as MGate5105:I.Data[3] and input Source B as 2. 3. Drag a MOV instruction to the end of Rung 0; then set Source as 2 and input Dest as MGate5105:O.Data[0]. The settings for Rung 0 checks the value of the PowerFlex logic command register. If the register value is not equal to 2, the PLC outputs this register as 2 and sets PowerFlex to Start Mode. 6.3 Editing MainRoutine 1. Click the MainRoutine task under Tasks > MainTask. 2. Drag a Examine On instruction to Rung 0. The S:FS input indicates that this routine is run once. 3. Drag a Jump To Subroutine instruction to the end of Rung 0 and set Routine Name as Init. To remove the Input Par, Input Par, and Return Par parameters that are not required, right-click on the parameters and select Remove Instruction Parameter. Copyright 2014 Moxa Inc. Page 27 of 36
4. Add Rung 1 and drag a GEQ instruction to Rung 1; then, set Source A as MGate5105:I.Data[6] and input Source B as 250. 5. Drag a MOV instruction to the end of Rung 1; then, set Source as 600 and Dest input as MGate5105:O.Data[1]. The settings for Rung 1 checks the value of the IAQPoint2 Temperature register. If the register value is not 250, the PLC outputs the PowerFlex speed register as 600. This means that if the temperature is greater than 25.0 C, PowerFlex speed is changed to 60 Hz. 6. Add Rung 2 and drag a GEQ instruction to Rung 2; then, set Source A as MGate5105:I.Data[6] and input Source B as 245. 7. Drag a LES instruction to Rung 2 and set input Source A as MGate5105:I.Data[6] and input Source B as 250. 8. Drag a MOV instruction to the end of Rung 1 and set Source as 600 and input Dest as MGate5105:O.Data[1]. Copyright 2014 Moxa Inc. Page 28 of 36
The settings for Rung 2 checks the value of the IAQPoint2 temperature register. If the range of the register value is between 245 and 250, the PLC would output PowerFlex Speed register as 500. This means that if the temperature range is between 24.5 C and 25.0 C, PowerFlex speed is changed to 50 Hz. 9. Add Rung 3~7 as shown in the following figure. The following table shows the logic of Rung 1~7. Rung Temperature (C ) >= < Drive Speed (MHz. ) 1 250-60 2 245 250 50 3 240 245 40 4 235 240 30 5 230 235 20 Copyright 2014 Moxa Inc. Page 29 of 36

8 Communication Test 8.1 Monitor Tags Select Controller Tags to view all the tags that you have created. You can monitor the IAQPoint2 and PowerFlex register values using Input Tags. For example, if you use a hairdryer to warm up IAQPoint2, this will increase the values of MGate5105:I.Data[6] and MGate5105:I.Data[4] tags. Copyright 2014 Moxa Inc. Page 33 of 36
8.2 Changing Tag Values You can change the value of Output Tags. For example, if you set the value of MGate5105:O.Data[0] to 1, PowerFlex changes to Stop Mode. 9 Appendix 9.1 PowerFlex 4M Modbus Registers Logic Command Register Address: 8192 Access: R/W Value: Bit(s) Description 0 1 = Stop, 0 = Not Stop 1 1 = Start, 0 = Not Start Reference Register: Setting Speed Address: 8193 Access: R/W Value: A decimal value entered as xxx.x where the decimal point is fixed.
