Logic
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
16.13.4 Setting example
For absolute comparison between inputs:
Set the EnaAbs = Absolute
RefSource = Input REF
Set the
Similarly for Signed comparison between inputs
EnaAbs = Signed
Set the
RefSource = Input REF
Set the
For absolute comparison between input and setting
EnaAbs = Absolute
Set the
RefSource = Set Value
Set the
SetValue shall be set between -2000000000 to 2000000000
Similarly for signed comparison between input and setting
EnaAbs = Signed
Set the
RefSource = Set Value
Set the
SetValue shall be set between -2000000000 to 2000000000
