ABB REB670 Series - Setting example; Comparator for real inputs - REALCOMP; Identification

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 .
13.13.4 Setting example
GUID-13302FD6-1585-42FE-BD6D-44F231982C59 v2
For absolute comparison between inputs:
Set the
EnaAbs = Absolute
Set the RefSource = Input REF
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
