I have a s7-318-dp system with a cp342-5 also being used because my profibus drops went over 126.I want to know how to call the data from the cp342-5 network(approx. 400 input bytes and 350 output bites) into the main program using FC2 (DP_RECV).
Do I call all the data combined or do I call only the 400 input bytes.
