Switch−on debounce time
Description
0.1 ms
3 ms (presetting)
10 ms
20 ms [Debounce time]
Note Input debouncing times are specified in order to eliminate interfering changes of
signal edge during switching procedures (bouncing of the input signal).
This setting applies to all inputs of the module.
Further information on this parameter can be found in the CPX system manual.
