Dear all
In a cascade loop, if PV of secondary PID goes to NaN control Valve directly control by primary PID, I don't want to put a switch block before AO channel. Is there any option in PIDA block (in Experion PKS R410) to controlling final control element by Primary PID in case of secondary failure?
