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 .
