Hi,

I am using the CP341 for modbus RTU in an ET200 rack.
Usually we are using the CP341 for this application in the same central rack as the CPU, and it is working. However, in the latest application we are using the same card in an external ET200 rack, connected by using Profibus. We are having some issues now, when testing it.

Does anyone know if there are any limitations to the CP341 card, when it is used in an ET200 rack, compared to using the card in a central rack next to the CPU?


Thanks!
