Operation principle
The comparison can be done in two ways,
• Between 2 inputs, INPUT and REF
• Between INPUT and the value set by the user SetValue.
The selection of reference value for comparison can be done through setting
RefSource. If RefSource is selected as Input REF then the reference value for
comparison is taken 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
