hello,
I am new to PID programming and I had a dumb question. I am trying to control a valve such that I can control the pressure downstream of the valve. My input and setpoint variable are the pressure transducer measurement. However my PID should output a 0-5VDC signal to the valve which will in turn control the pressure downstream. Can this be done using PID controls toolkit. If yes then perhaps some nudge in the right direction would be awesome. I do not understand the output part which goes from -100 to 100. what is the physical significance of that? can that be directly applied to the valve actuator with simple math functions?
Thanks,
Vickey
