17.13.3  Setting guidelines
GUID-ADA3E806-BEF1-4D15-B270-207386A0AEE4 v2
For proper operation of comparison the set value should be set within the range of
± 2 ×10
9
.
Setting procedure on the IED:
EnaAbs: This setting is used to select the comparison type between signed and
absolute values.
• Absolute: Comparison is performed on absolute values of input and reference
values
• Signed: Comparison is performed on signed values of input and reference
values.
RefSource: This setting is used to select the reference source between input and
setting for comparison.
• Input REF: The function will take reference value from input REF
• Set Value: The function will take reference value from setting SetValue
SetValue: This setting is used to set the reference value for comparison when
setting RefSource is selected as SetValue.
17.13.4  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
