Fig.2/10: Application example for parameterisation of the input debounce time and
signal extension time on the 2nd sensor
In the above application, packets are transported on a
fast−moving conveyor belt.
The input for the 2nd sensor is parameterised as follows for
improvement of the signal recording and processing:
 Reduction of the input debounce time from
3ms (factory
setting) to 0.1ms: Recording shorter signals is possible.
This parameter is set for the complete module.
 Signal extension time set to 50ms: Reliable recording of
the signals by the controller.
The value of this parameter is set for the complete
module but must be activated or deactivated separately
for each input channel.
