Improving the performance of a trigger model
To improve the performance of a trigger model:
• Reduce the number of blocks to less than 15.
• Do not use multiple reading buffers.
• Use four or fewer delay blocks.
• Use four or fewer measure blocks.
• Do not have multiple blocks waiting on the same event.
• Verify that constant delay blocks are set to less than 254 ms.
• Limit use of configuration list blocks.
Action overruns
An action overrun occurs when a trigger object receives a trigger event and is not ready to act on it.
The action overruns of all trigger objects are reported in a command for the associated trigger object.
See the appropriate sections on each trigger object for further details on conditions under which an
object generates an action overrun.
Some examples of action overruns include the following:
trigger.blender[N].overrun
trigger.digin[N].overrun
trigger.extin.overrun
trigger.lanin[N].overrun
trigger.timer[N].overrun
trigger.tsplinkin[N].overrun
