Issues regarding user-defined calculation blocks in the CENTUM VP system
Thread Content
Both the IN input and the Q01 input receive 4-20mA signals, with 12mA being the value applied to each. No calculations are performed; in block editing, CPV=RV and CPV1=RV1. However, the IN signal channel shows normal values, while the signal channel of the second input terminal Q01 displays significantly abnormal values. I’m not sure how to resolve this issue – could someone please help? Thank you!
Analog input signals are generally converted into corresponding data using modules such as PVI and PID before being fed into the calculation block
