Additional Information
The STEP instruction turns all outputs in its process OFF when ON 
changes to OFF.
Process A
Process C
Process B
Process D
Process E
Note  When processes (B) and (D) are in operation and SW5 and 
SW6 turn ON, it is judged that processes (B) and (D) are finished.
Execution of SNXT W0.04 turns OFF the outputs of process 
(B) and W0.03 turns OFF.
STEP W0.03 judges ON to OFF and turns OFF the outputs of 
process (D).
