Step Instructions
Section 3-22
The program for this process, shown below, starts with two SNXT(009)
instructions that start processes A and B. Because of the way CIO 000001
(SW A1) and CIO 000002 (SW B1) are programmed, only one of these will be
executed with an ON execution condition to start either process A or process
B. Both of the steps for these processes end with a SNXT(009) that starts the
step (process C).

Note
In the above programming, CIO 010002 is used in two
SNXT(009) instructions. This will not produce a duplication
error during the program check.
