Block Programming Instructions Section 3-30
Although EXIT (NOT)(806) is similar to IF-IEND programming, execution time
is normally shorter for EXIT (NOT)(806) because the instructions from EXIT
(NOT)(806) to the end of the block program are not executed at all.
3-30-6 ONE CYCLE AND WAIT (NOT): WAIT(805)/WAIT(805) NOT
Purpose Stops execution of the rest of the block program until an execution condition
turns ON or an operand bit turns ON or OFF.

Note WAIT(805)/WAIT(805) NOT must be used in block programming regions even
within subroutines and interrupt tasks.
