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
