controls on the live monitoring dialog box of Loop Control Function Blocks will handle Mode changes
and Accutune initiation.

The Mode change will also be reflected in the Live Monitor dialog box under “MODE”. See Figure 63.

Accutune
The PID, TPSC, and Carbon function blocks support Accutune. The On/Off function block does not. You
can initiate Accutune by selecting Accutune from the list of parameters and enabling it and activating the
“Accutune” button on the live monitor dialog box.
The Accutune button will remain depressed and disabled until the controller completes the operation.
To abort Accutune in the UMC800 put the loop in manual mode.
