5.2.7.3 Use as counter with Start/Stop
When using as counter with Start/Stop two digital inputs are allocated. The faster 1 kHz input is used
as counter and the slower 10 Hz input as Start/Stop.
Both inputs are configured according to their use
(see figure
and
. Here you also have to pay
attention to the debounce time for a defined signal
level.

5.2.7.4 Use as counter with Start/Stop via timeout
When using as counter with Start/Stop via timeout a single digital input is allocated. It is reasonable to
use the faster 1 kHz input for this, because it also functions as counter.
The counter for produced pieces is the signal for
a running machine concurrently. In order to no-
tice interruption or switching-off of the machine
the timeout is supervised. When the timeout has
run out without registering a counting impulse, an
interruption data record is created. The timeout is
put back after each impulse (change from Low to
High), that fulfils the conditions of the debounce
time.
Figure 130: Use as counter with Start/Stop via timeout
The cycle indicates the interval, in which a data record is created (irrespective of an impulse). It is
activated after the first impulse and deactivated after reached timeout. The cycle carries out the input
chain for Start and counting impulse.
