3.
Configure the expression and settings from the table below:
4.3.4.2 Example 2 - Multiple Expressions
Process Conditions:
A valve has two limit switches (TAGS VLV101 and VLV102). VLV101 is closed (VLV101.OUT=1) when the
valve is open and VLV102 is closed (VLV102.OUT=1) when the valve is closed.
Objective:
Assign dynamics to an instance of the submodel ISA_VLVE_ACTR on a graphic so that the submodel
instance is filled in white when the valve is open, unfilled when the valve is closed, and filled in yellow when
the state is unknown (i.e., both limit switches open or closed).
