Hi,
I have a CPU 1214C DC/DC/RLY and it communicates with a CP-1604 (Profinetcard) that is in the robotcabinet (R30iB). I have set it up in TIA Portal.
The fun thing is that the signals works between the PLC and Robot, but it still indicates error and says "Not Reachable" on PN-IO module and all the RJ45 ports.
I attach a screenshot for a "overview" in the TIA Portal.
Any clues how to get that annoying error to disappear?
Best regards Adam
