What is the minimum signal duration?
In contrast to the maximum dead time, a telegram is only sent after the minimum signal duration
has elapsed.
The individual functions are:
If an edge is detected on the input, the minimum signal duration will commence. No telegram is
sent on the bus at this time. The signal on the input is observed within the minimum signal duration.
If a further edge appears at the input during the minimum signal duration, it will be interpreted as a
new operation, and the minimum signal duration restarts. If no further edges occur after the start of
the minimum signal duration, a telegram is sent on the bus, after the minimum signal duration has
timed out.
Example: Minimum signal duration of the input signal for a detected edge:
In only two cases do no further edge changes occur within the minimum signal duration T
change of edge. For this reason, only both of these are detected as valid.
Note
The minimum signal duration is not considered after a download and/or ETS reset.
