Issue: IO-Link Sensors Not Connecting to AL1372 in Automation Studio

Hi everyone,

I’m working on integrating an IO-Link Master AL1372 (IFM) with my X20CP3687X PLC via Powerlink. Here’s the current situation:

  1. AL1372 Configuration in Automation Studio:
  • The master has been successfully imported and added to the Powerlink topology.
  • The communication between the PLC and the master appears functional (no errors in module monitoring).
  1. IODD Files for Sensors Imported:
  • I downloaded the IODD files for the temperature sensor (TA2145) and proximity sensor (KI6000) from IFM’s website.
  • These IODD files have been imported as DTM into Automation Studio.
  1. Problem:
  • Although the IODD files are imported, I cannot assign the sensors to the ports (e.g., X01, X02) of the master.
  • In the I/O mapping, only “Module OK” is displayed; no additional process data is visible.
  • I cannot find a way to bind the IODD files directly to the AL1372 or configure them properly within Automation Studio.

Questions:

  • Is pre-configuration of the IO-Link Master in a separate tool (e.g., LR Device) mandatory before using it in Automation Studio?
  • How can I ensure that the IODD data is correctly utilized in my project?
  • What are the specific steps to assign sensors to the AL1372 ports in Automation Studio?

Thanks in advance for your guidance! :blush:

Hello,

Its not possible to use the import and attach it to the IFM IOlink master.
This is only possible at the IOlink master like the X20DS438A or X67DS438A.

You can do everything from the PLC but its more cumbersome. Maybe someone can share a program/library to handle that ?

On the IFM website you can find a package with a PowerPoint etc how to use this IOlink master and configure your devices.

Dear Mr. Franken,

Thank you for the information. I understand that importing the IODD file with the IFM IO-Link Master is not possible, and I will proceed with handling the communication through cyclic commands in my PLC. I hope someone will share a program or library to assist with the implementation.

Thank you for your help. I will reach out if I have further questions.

Best regards,
Youness Hamouna
