Good morning, we have the same problem but with a Cerabar M5, the only difference is that we can see the Couppler FDC 157-0 performing well online, but the Cerabar we do not see.

We do not know if the Cerabar gsd has to go inside the IM in the hardware configuration or outside as another participant.

When we download the hardware to the PLC, the IM 153-2 and FDC 157 are fine but the cerabar is not on the network and the error message is that we don´t have this station.

We upload PDF file with the problem.

Thank´s for reading us and we hope you can help us.​
