Hello,
I have 2 PIDE's controlling the same valve. One, opens the valve to a setpoint pressure. it switches to the other PIDE to close the valve if motor goes in overcurrent. I have both PIDE's going into a SEL that picks which output to use. Here's the question: i am using valve feedback position into CVPrevious for a bumpless transfer feature. if I enable a different PID with the actual valve position loaded into CVPrevious, is that where the CV will start from? in otherwards, i don't want one calculating while the other is controlling-Or even if it does- i want it to start at the present valve position. thoughts??
