Settable time limits for warning and alarm are provided. The time limit for
overflow indication is fixed to 999999.9 seconds.

Setting guidelines

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.
Comparator for integer inputs - INTCOMP
Identification
Function description
Comparison of integer values
Application
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.
