lan.trigger[N].overrun 
This attribute contains the event detector's overrun status. 
Type  TSP-Link accessible  Affected by  Where saved  Default value 
Attribute (R)  Yes  LAN trigger N clear
LAN trigger N reset
Instrument reset 
Recall setup 
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

Usage 
protocol = lan.trigger[N].protocol 
lan.trigger[N].protocol = protocol 
 
protocol 
The protocol to use for the trigger's messages: 
•  0 or lan.TCP 
•  1 or lan.UDP 
•  2 or lan.MULTICAST 
N
