If the values are above this range, the resolution becomes lower due to the 32 bit float
representation
99 999.99 seconds < tAlarm ≤ 999 999.0 seconds
99 999.99 seconds < tWarning ≤ 999 999.0 seconds
Note that tAlarm and tWarning are independent settings, that is, there is
no check if tAlarm > tWarning .
The limit for the overflow supervision is fixed at 999999.9 seconds.

16.13.2 Application
GUID-4C6D730D-BB1C-45F1-A719-1267234BF1B9 v1
The function gives the possibility to monitor the level of integer 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.
16.13.3 Setting guidelines
GUID-ADA3E806-BEF1-4D15-B270-207386A0AEE4 v2
For proper operation of comparison the set value should be set within the range of ± 2
×10
9
.
Setting procedure on the IED:
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.
