The PID Process Controller dialog box (Figure 55) contains the tools for managing the

PID function block. It is composed of frames that group controls and displays:

❑ The PID Status frame displays and controls the PID States (block modes),

Setpoint and Process Variable, and the Device tagname. In Manual State (M),

drag the PID output slider to move the valve. In Local State (L), drag the Setpoint

Slider (or enter a value in the Setpoint text box) to change the process variable

Set Point. In Cascade (C), and in Remote cascade (R), the Set Point is

controlled by a function block or remote application.

❑ Others frame: Click Change to access the Change PID Parameter dialog to tune

the P, I and D parameters. The Alarm Status fields display the actual pressure,

cascade and remote cascade setpoints and turn red when in alarm.

❑ PID Output and Valve Position: Use the slider to tune the PID output and see the

valve position above.
