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: The function will do absolute comparison between input and reference
value
• Signed: The function will do signed comparison between input and reference value
RefSource: This setting is used to select the reference source between input and setting for
comparison.
• REF: The function will take reference value from input REF
• SetValue: 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 = 1
