The function gives the possibility to monitor the level of real 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.
9.14.3 Setting guidelines
GUID-DE69FF5B-7D34-4A30-9060-214E98BFF798 v2
Setting procedure on the IED:
EnaAbs: This setting is used to select the comparison type between signed and
absolute values.
• Absolute: Comparison is performed with absolute values of input and
reference.
• Signed: Comparison is performed with signed values of input and reference.
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 Set Value. If this setting value is less than 0.2% of
the set unit then the output INLOW will never pickup.
RefPrefix: This setting is used to set the unit of the reference value for comparison
when setting RefSource is selected as SetValue. It has 5 unit selections and they are
Milli, Unity, Kilo, Mega and Giga.
