Starting up the device - Configuration
The standard switch-off function at reading gate start is rather unsuited for this module since it causes the
event counter to be reset on each reading gate start. Suitable as switch-off function for this example is the
valid read result function; otherwise, all switch-off functions are deactivated.
8.12.2 Parameters for operating as an input
Debounce time
Parameter for setting the software debounce time for the switching input. The definition of a debounce time
extends the signal transition time accordingly.
If the value of this parameter = 0, no debouncing takes place; otherwise, the configured value represents
the duration in milliseconds for which the input signal must be present and stable.

Start-up delay td_on
If the value of this parameter = 0, no start-up delay occurs for the activation of the input function; otherwise,
the configured value represents the time in milliseconds by which the input signal is delayed.
Switch-on time ton
This parameter specifies the min. activation duration for the selected input function in milliseconds.
The actual activation duration is calculated from the switch-on time as well as the switch-off delay.
Switch-off delay td_off
This parameter specifies the duration of the switch-off delay in milliseconds.
