Scan input after download,
bus reset and bus voltage recovery
Options:
no
yes
yes: The object value is scanned after a download, bus reset and
bus voltage recovery.
no: The object value is not scanned after a download, bus reset and
bus voltage recovery.
With option yes the following additional parameters are visible in the
parameter:
Inactive wait state after bus voltage-
recovery in s [0...30,000]
Options:
0...30,000
Here the waiting time after a bus voltage recovery is set. After the
waiting time has elapsed the state on the input terminals is scanned.
The input reacts as if the state on the input terminals has just been
set/not set.
Note
The inactive waiting time does not add to the actual, adjustable
send delay time. This can be set separately.
Debounce time
Options:
20/30/50/70/100/150 ms
Debouncing prevents unwanted multiple operations of the input,
e.g. due to bouncing of the contact.
What is the debounce time?
If an edge is detected at an input, the input will react immediately to
this edge (e.g. by sending a telegram). At the same time, the duration
of the debounce time T
evaluated within the debounce time duration.
Example: Debounce time of the input signal for a detected edge:

Detected pulse edge
After detection of an edge on the input, further edges are ignored for
the debounce time T
starts. The signal on the input is not
