FUNCTION_BLOCK FACEPLATE

Hover on a highlighted element
to pop up its description (if any).


An instance of this function block type displays the process variable (PV) and output (OUT), and provides user input of the set point (SP), for a closed-loop controller. The values of these variables are treated as percent of full scale.

The LABEL input provides a top-centered label for the faceplate ( TANK LEVEL in this example).

The AUTO output provides for user control of the controller mode via the Auto/Manual radio buttons.

See the TANK_MVCL system configuration for an example of the usage of an instance of this type.
