Limit counter (L4UFCNT) is intended for applications where positive and/or negative
sides 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.
