Usage

Details

If this is true, an event was ignored because the event detector was already in the detected state when the

event occurred.

This is an indication of the state of the event detector built into the line itself. It does not indicate if an overrun

occurred in any other part of the trigger model or in any other detector that is monitoring the event.

Example

overrun = digio.trigger[1].overrun

print(overrun)

If there is no trigger overrun, the following

text is output:

false
