A
Having the following:
MV - Manipulated variable
SP - Setpoint
PV - Process variable.
We are using a Q series mitsubishi PLC and using the PID block provided by the supplier.
Current configuration:
Auto: The block runs in Auto and controls as it should.
Manual: The function block, when set in Manual, the SP value is transferred to the MV output of the block. Any change on the SP is reflected on the MV. This is all fine.
Question is how to make the changeover bumpless?
