Periodical count
Definition
In this operating mode the electronic module counts periodically after the release signal is set
within the defined counter range and in the defined main count direction:
1 No main count direction
If the counter counts up and reaches the upper or lower count limit, it will jump to the load value
when another counter signal is received, and will continue to count from there without losing a sig-
nal.
2 Main count direction up
If the counter counts up and reaches the upper count limit, it will jump to the load value when
another counter signal is received, and will continue to count from there without losing a signal.
If the counter counts down and reaches the lower count limit, it will jump to the upper count limit
when another counter signal is received, and will continue to count from there.
3 Main count direction down
If the counter counts up and reaches the upper count limit, it will jump to the lower count limit
when another counter signal is received, and will continue to count from there.
If the counter counts down and reaches the lower count limit, it will jump to the lower count limit
when another counter signal is received, and will continue to count from there.
The following three diagrams show the counter's behavior in ”periodical count” mode with the
three main count directions: none, up, down.
