This is a common question that I encounter and it has come to me from engineers in every industry. Among other symptoms you may be experiencing, the process variable never comes to setpoint. Your output may also reverse direction in strange & unpredictable ways.
This is an illustrated example of this problem and its consequences:
In an ideal world, the solution would be implemented when your plant is commissioned or in this case, when you first configure your DeltaV system. If you’ve missed that boat, I believe asking this question will likely solve your issue: Have you checked this parameter? PID/ARW_HI_LIM
The Likely Solution? The Need to Set the ARW Parameter Equal to the Out Parameter.
ARW_HI_LIM = OUT_HI_LIM
