from second input signal (REF). If RefSource is selected as Set Value then the reference
value for comparison is taken from setting (SetValue).
The comparison can be done either between absolute values or signed values and it
depends on the setting EnaAbs. If EnaAbs is selected as Absolute then both input and
reference value is converted into absolute values and comparison is done. If EnaAbs is
selected as Signed then the comparison is done without any conversion.
The function has three state outputs high, low and equal to condition. It will check the
following condition and give corresponding outputs.
• If the input is above the reference value then INHIGH is set HIGH
• If the input is below the reference value then INLOW is set HIGH
• If the input is equal to reference value then INEQUAL is set HIGH
