The function gives the possibility to monitor the level of integer values in the system
relative to each other or to a fixed value. It is a basic arithmetic function that can be
used for monitoring, supervision, interlocking and other logics.

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.

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
