Comparator for integer inputs - INTCOMP

Identification
Function description
Comparison of integer values
Application
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
For proper operation of comparison the set value should be set within the range of ± 2
9
×10 .
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.
Setting example
For absolute comparison between inputs:
Set the EnaAbs = Absolute
Set the RefSource = Input REF
