Details
The branch-on-event building block goes to a branching block after a specified trigger event occurs. If the trigger
event has not yet occurred when the trigger model 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 the trigger
model reaches the branch-on-event block, it goes to the branching block.
The event can be one of the events shown in the following table.
