trigger.digin[N].overrun
This attribute returns the event detector overrun status.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (R) Yes
Digital I/O trigger N clear
Digital I/O trigger N reset
Not applicable Not applicable
Usage
overrun = trigger.digin[N].overrun
overrun
Trigger overrun state (true or false)
N
Digital I/O trigger line (1 to 6)
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 = trigger.digin[1].overrun
print(overrun)
If there is no trigger overrun on digital
input 1, the output is:
false
