VALUE6 INTEGER - - Output of counter 6
12.2.7 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. The maximum count up speed is 10 pulses per second. The
maximum counter value is 10 000. For counts above 10 000 the counter will stop at 10
000 and no restart will take place.
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.
12.2.7.1 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.
