Hi all,
I have a request from client as follows,
There's one PID for Control valve which would be controlling on basis of temperature. One setpoint should be entrered in Degree C from Local HMI, but the Remote Control wants to write the Setpoint in Fahrenheit. No Local/Remote selection button required by client on graphics.
Suppose if Setpoint in Fahrenheit changes then it moves to PID setpoint and convert the setpoint of Fahrenheit to Degree C and move it to setpoint C as well for local operator information. Same in case of If Setpoint Degree C changed by Operator then it moves to PID SP and convert the Degree C SP to Fahrenheit and move to Setpoint F.
This is confusing for me, I've tried many methods but didn't get it working. Need inputs from your side
