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.
