Settable time limits for warning and alarm are provided. The time limit for
overflow indication is fixed to 999999.9 seconds.
14.12.3 Setting guidelines
GUID-2911D624-87D5-4427-BB2F-E0D1072394FA v3
The settings tAlarm
and tWarning are user settable limits defined in seconds. The
achievable resolution of the settings depends on the level of the values defined.
A resolution of 10 ms can be achieved when the settings are defined within the
range
1.00 second ≤ tAlarm ≤ 99 999.99 seconds
1.00 second ≤ tWarning ≤ 99 999.99 seconds.
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.

14.13.2 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.
