Explanation of operation
(1) SW1, SW2 ON:
Conveyor (A) operates
Work (A) operates
Conveyor (C) operates
Work (C) operates
(2) SW3 ON:
Process (A) stops
Conveyor (B) operates
Work (B) operates
(3) SW4 ON:
Process (C) stops
Conveyor (D) operates
Work (D) operates
(4) SW5, SW6 ON:
Process (B) stops
Process (D) stops
Conveyor (E) operates
Work (E) operates
(5) SW7 ON:
Process (E) stops
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).
Additional Information
The STEP instruction turns all outputs in its process OFF when ON
changes to OFF.
