On event block
The branch-on-event block branches to a specified block when a specified trigger event occurs. If the
trigger event has not yet occurred when trigger model execution reaches the branch-on-event block,
the trigger model continues to execute the blocks in the normal sequence. After the trigger event
occurs, the next time trigger model execution reaches the branch-on-event block, it goes to the
branching block.
Trigger events are reset when the trigger model is at the start block, so only events that occur after
you start trigger model execution are detected by the branch-on-event block. The event is also reset
after trigger model execution completes the branching block.
When you select the branch-on-event block, the following options are available.
Setting Description
Event
The event that causes this block to branch
Branch to Block
The block number to execute when the specified event occurs
The event can be any of the events described in the following table.
