Type TSP-Link accessible Affected by Where saved Default value
Attribute (R) Yes LAN trigger N clear

Not applicable Not applicable
Usage
overrun = lan.trigger[N].overrun
overrun
The trigger overrun state for the specified LAN packet (true or false)
N
A number representing the LAN event number (1 to 8)
Details
This attribute indicates whether an event has been 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 synchronization line itself. It does not indicate
if an overrun occurred in any other part of the trigger model, or in any other construct that is monitoring the event.
It also is not an indication of an output trigger overrun. Output trigger overrun indications are provided in the
status model.
Example
overrun = lan.trigger[5].overrun
print(overrun)
Checks the overrun status of a trigger on LAN5 and
outputs the value, such as:
false
