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

− IP Address: Select this option and enter the IP address.

− Connection Parameters: Set the Size (Input 8 and Output 2) and the Assembly Instance

(Input 110 and Output 100) that is determined by MGate 5105-MB-EIP.

5.6 Creating an MGate Module 1. In the Select Module Type screen, select MGate and click Create.



2. Configure the module name and IP address; then click Change.



3. In the Module Definition screen, Select INT (unit: 16bits) from the drop-down list and

set the input size as 8 and output size as 2.

5.7 Tags Description In the Controller Organizer tree menu, select Controller Tags under Controller Demo to

view all the tags you have created. Verifying that all the required tags are created and

configure the Description fields associated with the input and output data tags.



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.



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.



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].



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



Rung Temperature (C ) Drive Speed (MHz. )

6 225 230 10

7 - 225 0

7 Downloading a Project to PLC

1. Select File > Save to save this project.

2. Select Communications >Who Active to search for the target PLC.



3. In the Who Active screen, expand the EtherNet/IP network node and select

Backplane > 00, 1756-L71 LOGIX5571; then, click Download to download the

project to the PLC.

When a message appears to warn you to that you are downloading an offline project to the

PLC, click Download to continue.



The RSLogix 5000 main screen displays green indicators as shown in the following figure.



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.



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.
