Comparator function block parameters

The following table lists the system parameters for the Comparator function block.

Table: Comparator function block parameters
Parameter	Units	Description
COMP_VAL1	Determined by source	The first comparative value. Used to compare with DISC_VAL in calculating EQ, GT, LT, and NEQ. Used as part of the range that DISC_VAL compares against to calculate IN_RANGE.
COMP_VAL2	Determined by source	The second comparative value. Used as part of the range that DISC_VAL compares against to calculate IN_RANGE.
DISC_VAL	Determined by source	The input comparison value. Used with COMP_VAL1 in calculating EQ, GT, LT, and NEQ. Compared against the range of COMP_VAL1 - COMP_VAL2 to calculate IN_RANGE.
EQ	None	Equal to. Compares COMP_VAL1 with DISC_VAL. Discrete output (True=1/False=0).
GT	None	Greater Than. Compares COMP_VAL1 with DISC_VAL. Discrete output (True=1/False=0).
IN_RANGE	None	In range. Compares DISC_VAL against the range of COMP_VAL2 and COMP_VAL1.
LT	None	Less Than. Compares COMP_VAL1 with DISC_VAL. Discrete output (True=1/False=0).
NEQ	None	Not Equal To. Compares COMP_VAL1 with DISC_VAL. Discrete output (True=1/False=0).
