Question: CPPPO Server configuration as Generic Ethernet Module in Studio 5000

[damian-stempel-xberry]

Hi,
did anyone successfully configure CPPPO Server/Adapter to communicate as Generic Ethernet Module in Studio 5000?

I tried to use one of the provided examples (poll_test.py) and create my own server, only with few attributes (enip_server --print SCADA@22/1/1=INT[1000] TEXT@22/1/2=SSTRING[100] FLOAT@22/1/3=REAL), but all attempts finished with the same result - errors below.

I'm not familiar with CIP communication, so apologize if I misunderstand the concept of communication, or try to do something in an improper way. I would be grateful for any working examples or information what is wrong with my configuration. As I understand, I use the wrong service, but I'm not sure how to configure the proper one.
