1. Overview

In this article, it will be explained how to connect a ctrlX COREplus X3 with a IndraControl XM21 using the PROFINET connection. This connection can also be done between a ctrlX CORE X3 and an IndraControl XM21. The IndraControl will be first configured using the IndraWorks Engineering program, and the ctrlX CORE will be configured with the CoDeSys Profinet libraries using ctrlX PLC Engineering program.

2. Prerequisites

• ctrlX PLC app
• CoDeSys Fieldbus libraries
• PLC Engineering program
• IndraWorks Engineering program

3. IndraControl XM21 configuration

Note: It will be assumed that the user knows how to install the IndraWorks Engineering program

1. Connect the IndraControl XM21 to the Engineering computer using the Ethernet port located in the IndraControl XM21 (XF5) and plug it to the computer Ethernet port. Make sure to establish correctly the static IP address. Once done this, open the IndraWorks Engineering program and create a new project:

1. Create a new project
2. Select "empty project"
3. Enter a project name
4. Press "Ok"

2. Add device

1. Right click over the project name
2. Press "Add"
3. Select "Add" again
4. Choose the type of IndraControl (In this case we will use the IndraControl XM2 series)

3. Choose an IP address for the PN-Device
4. Configure the IP address range

4. Add PN-Device description: To be able to scan and recognise the Profinet device or to add the PN-Device it is required to install the device description. In this case, the ctrlX CORE description is needed.

• Press the following link and download the ctrlX CORE device description

• Return back to the IndraWorks Engineering program, and select "Tools" -> "Device database"

• Press "Add devices" 

• Select the previously unzipped .xml file.

5. Add PN-Device to the devices tree

1. Right click over "PROFINET_IO_Controller_XM"
2. Select "Add"
3. Select "Add" again

1. Select the I/O section
2. Double click over CODESYS Profinet Device
3. Close the window

• Configure CODESYS Profinet Device

1. Double click over CODESYS Profinet Device
2. Define a station name
3. Check the IP address

• Add input:

1. Right click over "ctrlx-core-xcr"
2. Add
3. Module
4. Input
5. Select "Input 8 Bit"

• Follow the same steps for the output:

1. Right click over "ctrlx-core-xcr"
2. Add
3. Module
4. Input
5. Select "Output 8 Bit"

6. Write a little program to write values 

• Global variable definition

1. Double click over "UserVarGlobal"
2. Define the variable "counter"

• Program definition

1. Double click over "PlcProg (PRG)"
2. Define variables
3. Write the lines of code:

//Counter
UserVarGlobal.counter := UserVarGlobal.counter + 1;
//Input will take the counter value
input := UserVarGlobal.counter;
//Equal output with input
output := input;

7. Map the variables

• First, the input variable will be mapped

1. Double click over "Input_8Bit(Input 8Bit)"
2. Select the I/O Mapping tab
3. Write the desired variable to map. In this case it will be the "input". To add it it is required to write "Application.PlcProg.input"

Note: To find easier the variable, double click over the black space, expand the tree and double click over the variable

• The same steps are followed for the output variable:

1. Double click over "Output_8Bit(Output 8Bit)"
2. Select the I/O Mapping tab
3. Double click over the blanck space or press over the three points
4. Expand the "Application" tree -> Expand the PLC program tree to find the defined variables
5. Double click over the "output" variable
6. Press "Ok" to close the window

4. ctrlX COREplus X3 configuration

• In this section, it will be shown how the ctrlX COREplus X3 has to be configured. First, connect the ctrlX CORE to the Engineering computer using the Ethernet connection. It is recommended to check the instructions shown in the following link: Quick Start Guide ctrlX CORE 

1. Open ctrlX PLC Engineering program and create a new project

1. Select "New project"
2. Select the ctrlX CORE template
3. Provide a project name

• In the Profinet IO Module -> Output, select "Output 8Bit" and click over "Add device"

• Now that both devices are configured, we are ready to test the connection
  
  

5. Testing

1. In the ctrlX PLC Engineering program, generate code and transfer the PLC program to the ctrlX CORE

2. Accept the program creation by clicing over "Yes"

5. Accept the message by clicking over "Yes"

6. Press the Run button

• Accept the message by clicking over "Yes"

Note: If everything works fine, the following symbols should be visible in the PLC Engineering program

• In the case it does not work, perform a "Reset cold" and run the PLC program again

• To check the received values, go to "Output_8bit" and check if the values are updated

• If the values are not updated as shown in the previous image, it is required to follow the steps:
