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
Set the EnaAbs = Signed
Set the RefSource = Set Value
SetValue shall be set between -2000000000 to 2000000000

16.15.2 Application
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.
16.15.3 Setting guidelines
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.
