I want to use multi-instance PID, I have create some static pid_compact data tipe in a FB and i called this FB from OB30. ¿Is this a correct way to implement multi-instance PID in Tia Portal?
I use the instance db of the PIDs to configure it but I dont kwno how I can Start the PID. I want something similar like start button when use pid without multi-instance and appear in Commissioning of technology objects.
PID_Compact is called in the constant time scale of a cycle interrupt OB.
If you call PID_Compact as a multi-instance DB, no technology object is created. No parameter assignment interface or commissioning interface is available. You must assign parameters for PID_Compact directly in the multi-instance DB and comision it via a watch table
