14.8.2 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.

GUID-225D8341-2D31-49F1-9B49-571346C0FE26 v1
The function is used for user-defined logics and it can also be used for different purposes
internally in the IED. An application example is to accumulate the total running/energized time
of the generator, transformer, reactor, capacitor bank or even line.
Settable time limits for warning and alarm are provided. The time limit for overflow indication
is fixed to 99999.9 hours. At overflow the accumulated time resets and the accumulation
starts from zero again.
