Some tips:
Make sure, that you assign unused IP address;
CP briefly stops while program transfers connection data;
Ensure, that communication data is sent each time after power loss (OB100 will help you to handle this);
ACT needs to be set to TRUE untill DONE arrise;
Always evaluate errors, it will save your time to find the problem.
