Multiplying a value to the Setpoint entered by operator in the Input Field.
Is it possible to multiply / divide some value to the value entered by operator in the input field without doing any logic in the controller.
that is depends
if your operator panel software support the scripts
then it will be possible ... but is the engineering stage not in the operation stage
unless you made aformula that do the Divide/Multiply in the Script to be ready for the data entry from th operator
hope that is clear
Just because it is "possible" does not make it a good idea.
Manipulating values in PG2 graphics before writing them to the controller is bad practice, and will be very confusing to others who have to debug and troubleshoot your code sometime in the future.
Put logic like this where it belongs - in the controller.
