$SSOLFDWLRQ
The function consists of six counters which are used for storing the number of times
each counter has been activated. It is also provided with a common blocking function
for all six counters, to be used for example at testing. Every counter can separately be
set on or off by a parameter setting.

The function block has six inputs for increasing the counter values for each of the six
counters respectively. The content of the counters are stepped one step for each positive
edge of the input respectively. 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. At power interrupt the counter values are stored.
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.
All inputs are configured via configuration tool CAP.
