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

14.14.2 Application

GUID-5F7B1683-9799-4D27-B333-B184F8861A5B v1

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.

14.14.3 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
