however gives as a result that it can take long time, up to several minutes, before a new
value is stored in the flash memory. And if a new CNTGGIO value is not stored before
auxiliary power interruption, it will be lost. CNTGGIO stored values in flash memory
will however not be lost at an auxiliary power interruption.
The function block also has an input BLOCK. At activation of this input all six
counters are blocked. The input can for example, be used for blocking the counters at
testing.The function block has an input RESET. At activation of this input all six
counters are set to 0.
All inputs are configured via PCM600.
14.2.7.1 Reporting
The content of the counters can be read in the local HMI.
Reset of counters can be performed in the local HMI and a binary input.
Reading of content can also be performed remotely, for example from a IEC 61850
client. The value can also be presented as a measuring value on the local HMI
graphical display.

14.3.2 Introduction
Limit counter (L4UFCNT) provides a settable counter with four independent limits
where the number of positive and/or negative flanks on the input signal are counted
against the setting values for limits. The output for each limit is activated when the
counted value reaches that limit.
