Count value: Current counter content
Ticker value: After mains connection, a timer (s ticker) is started which restarts at 0 after 65535 s.
With every change of the count value, the time value of the timer is stored as 16-bit-s value
together with the count value in the input area.
Write data: 10 bytes
Comparison value: Here you can specify a value which, by comparison with the current counter
content, is able to influence the counter output or trigger a process alarm. The response of the
output or of the process alarm can be parameterised.
Set value: With an edge change 0-1 of COUNTERVAL_SET in the control word, the set value is
accepted in the counter.
