Software cams

Because the hardware timer is also used for the "software cam" function, it is not possible to
use the "clock-independent switching signal output" function with software cams at the same
time.
The following alarm appears in the event of an error:
Alarm 75500 "Channel
switching signal output"
A description of the software cams can be found in:
