PROFINET/IO-Link Gateway from ELCO: Some IOs are not transmitted

Hello Community,
I’m currently trying to implement a PROFINET Device from ELCO (FCPN-8LKM-4A4B) where IO-Link Devices can be connected (so the FCPN-8LKM-4A4B Device is somehow working as a Gateway).
On the B&R side I’m using a X20CP1684 with the PROFINET Master X20IF10E1-1:

For my Tests I’m using a 16 Channel Input/16 Channel Output (Digital) IO-Link Device also from ELCO (LKHA-1616P-QA) which is connected to Port 1 of the FCPN-8LKM-4A4B. The Device Configuration of the PROFINET Device was done in following steps:

  • In the “Modules” section I’ve configured the IO-Link Device on Slot 1 via a drop-down menu:
  • On the Device itself I’ve configured Port 1 as IO-Link Interface
  • That’s basically all what I’ve done in the Device Configuration of the PROFINET Device (Apply Settings)

The settings of the PROFINET Master Interface are also kept like default settings.

I’m now facing the following issue: I can set the Digital Output of the IO-Link Device from the IO Mapping (see picture below) and I can also see on the IO-Link Device itself that the outputs are set. But the Digital Inputs are for some reason not transmitted back to the PLC and when I physically set an Input on the IO-Link Device (The LED on the IO-Link Device itself confirms that the Digital Input is active) there are no changes in the IO Mapping.

When I connect the IO-Link Device to an X20DS438A everything is working fine (Inputs as well as outputs).

Has someone of you experience with such a device and maybe some ideas what can be the issue here or what I’ve missed in the configuration part?

Thanks in advance for your help/hints :slight_smile:

Can someone help Kevin? we have here some experts for communication and configuration in AS. …

Hello Kevin,

did you follow the instructions for the ELCO IOLink Master? You have to install the ELCO control tool and insert the sensor into the corresponding port.
