For absolute comparison between inputs:
Set the EnaAbs = Absolute
Set the RefSource = Input REF
Similarly for Signed comparison between inputs
Set the EnaAbs = Signed
Set the RefSource =Input REF
For absolute comparison between input and setting
Set the EnaAbs = Absolute
Set the RefSource = Set Value
SetValue shall be set between -2000000000 to 2000000000
Similarly for signed comparison between input and setting
Set the EnaAbs = Signed
Set the RefSource = Set Value
SetValue shall be set between -2000000000 to 2000000000
