17.7.3 Setting guidelines
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.

Limit counter L4UFCNT -
17.8.2 Application
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.
17.8.3 Setting guidelines
The parameters for Limit counter L4UFCNT are set via the local HMI or PCM600.
