Block Programming Instructions Section 3-30
Note If the block program that is being paused appears after BPPS(811), it will not
be executed. If the block program appears before BPPS(811), it will be
paused starting the next cycle.
If CIO 0.00 is ON, the following program pauses execution of either block pro-
gram 1 or block program 2 depending on the status of CIO 0.01. The block
program that was paused is then restarted after 10 seconds.
3-30-4 Branching: IF(802), ELSE(803), and IEND(804)
Purpose Branches the block program either based on an execution condition or on the
status of an operand bit.

regions even within subroutines and interrupt tasks.
