Reference Manual

Details
The branch-once-excluded block is ignored the first time the trigger model encounters it. After the first
encounter, the trigger model goes to the specified branching block.
The branch-once-excluded block is reset when the trigger model starts or is placed in idle.
Example
trigger.model.setblock(2, trigger.BLOCK_BRANCH_ONCE_EXCLUDED, 4)
When the trigger model reaches block 2 the first time, the trigger model goes to block 3. If the trigger model
reaches this block again, the trigger model goes to block 4.

Details
When trigger model execution reaches the buffer clear trigger block, the instrument empties the
specified reading buffer. The specified buffer can be the default buffer or a buffer that you defined.
If you are clearing a user-defined reading buffer, you must create the buffer before you define this
block.
Example
trigger.model.setblock(3, trigger.BLOCK_BUFFER_CLEAR, capTest2)
Assign trigger block 3 to buffer clear; when the trigger model reaches block 3, it clears the reading buffer
named
capTest2
.
