Verifying Proper Operation
Follow these steps to verify that your PID loop operates properly:
In the Monitoring tab, double-click on FIC102. The PID diagram opens.
On the PID block, look at the MODE parameter to ensure that it is set to
MAN (manual).
With the PID block in manual mode, double-click on the OP parameter and
set it to 80.
On the PID block, double-click on the MODE parameter and set it to AUTO
(automatic).
Double-click on the setpoint wire and set the setpoint to 25.0.
Verify that the PID OP output value (displayed near the wire) changes.
Change the NUMERIC.PV to 20, then 30. Observe the OP output of the PID
block for changes.
