RefSource is selected as SetValue .
16.13.4 Setting example
GUID-13302FD6-1585-42FE-BD6D-44F231982C59 v2
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
