The pulse time t is the only setting for the Logical signal status report
(BINSTATREP). Each output can be set or reset individually, but the pulse time
will be the same for all outputs in the entire BINSTATREP function.

15.8.2 Application
GUID-41B13135-5069-4A5A-86CE-B7DBE9CFEF38 v2
Limit counter (L4UFCNT) is intended for applications where positive and/or
negative flanks on a binary signal need to be counted.
The limit counter provides four independent limits to be checked against the
accumulated counted value. The four limit reach indication outputs can be utilized
to initiate proceeding actions. The output indicators remain high until the reset of
the function.
It is also possible to initiate the counter from a non-zero value by resetting the
function to the wanted initial value provided as a setting.
If applicable, the counter can be set to stop or rollover to zero and continue
counting after reaching the maximum count value. The steady overflow output flag
indicates the next count after reaching the maximum count value. It is also possible
to set the counter to rollover and indicate the overflow as a pulse, which lasts up to
the first count after rolling over to zero. In this case, periodic pulses will be
generated at multiple overflow of the function.
