Fig.2/22: Application example for parameterisation of input debounce time and signal
extension time on the 2nd sensor
In the above application, packages are transpor ted on a
fast−moving conveyor belt.
For improvement of signal recording and processing, the
input for the 2nd sensor is parameterised as follows:
 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/deactivated separately for
each input channel.
