11.3 Single-channel counter
Jetter AG
85
Using manual pulse stretching, incrementation of the single-channel counter reading
can be stopped, or re-started through the application program. When doing so, it has
to be taken into account that the write process for enabling and disabling manual
pulse stretching via register 3xx1 and 3xx2 requires a short turnaround time, which
is not exactly quantifiable. In the worst case, the turnaround time is within several
milliseconds.
The maximum pulse length is given in the technical data on the inputs (for
more information refer to chapter "Technical Data of Digital Inputs", page 30).

Note!
In case of erronous readings, the software filter settings and edge evaluation
parameters have to be checked first.
