Mapping contents
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.
Count value:
Current counter content
Latch value:
If there is a positive edge at the latch input, the count value is stored here.
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.
