Operation principle

Event counter (CNTGGIO) has six counter inputs. CNTGGIO stores how many times
each of the inputs has been activated. The counter memory for each of the six inputs is
updated, giving the total number of times the input has been activated, as soon as an input
is activated.
To not risk that the flash memory is worn out due to too many writings, a mechanism for
limiting the number of writings per time period is included in the product. This 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.
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.
