Refer to the ZEN-SOFT01-V4 ZEN Support Software Operation Manual (Z184) for information on programming LED-type CPU Units. Example Program SW1 Ry SW2 Ry 3-3-1 Power supply terminals I/O Wiring and Internal Operation L SW1 SW2 N N I0 I1 Input terminals I2 I3 Connect switches SW1 and SW2 between N and input terminals I0 and I1. When SW1, connected to input bit I0, turns ON or OFF, I0 (indicated by (1) in the diagram) turns ON or OFF. When SW2, connected to input bit I1, turns ON or OFF, I1 (indicated by (2) in the diagram) turns ON or OFF. If the ladder program is executed in RUN mode and SW1 turns ON, input bit I0 turns ON, output bit Q0 turns ON, and the output contact (indicated by (3) in the diagram) turns ON. When the output contact (3) turns ON, the load connected to output terminal Q0 turns ON.

[. . . ] In this example, the carwash operates for 3 minutes if one coin is inserted, 6 minutes if two coins are inserted, and 9 minutes if 3 coins are inserted. A holding timer is used as the timer. 152 Application Examples Appendix E System Configuration 100 Coin selector I0 NC I0 3 min 9 min 10C1AR-A-V2 ZEN10C@AR-A-V2 Carwash operation Q0 Q0 Program Example 00 01 02 03 04 05 06 07 08 09 10 11 I0 M0 M0 H0 H0 M1 M1 H1 H1 M2 M2 H2 I0 M5 [H2 I0 H2 [M2 Insertion of 3rd coin detected H0 [M0 M3 Insertion of 1st coin detected 12 13 14 15 H0 H1 H2 #0 H0 H1 H2 M3 M4 M5 H1 H2 [Q0 T#0 Carwash drive output Holding timer startup Self-holding for 1st coin cleared Self-holding for 2nd coin cleared Self-holding for 3rd coin cleared I0 [H0 [M3 [M4 [M5 R#0 I0 H1 [M1 Insertion of 2nd coin detected 16 17 18 19 20 I0 M4 [H1 Holding timer reset Parameter Settings Holding Timer Set to 3 minutes. 153 Application Examples Appendix E Warming Molding Machines (Weekly Timer and Bit Logic) Application The ZEN can be used to improve molding efficiency by warming up the molding machine before the work shift starts. This allows molding work to begin immediately at the start of the work shift. When work shifts vary, pre-set weekly timers can be selected using a switch.
