Reading Ladder PLC Programming for Traffic Light PLC Program with PLC Omron :

Step 1 :
Sequence for Green Light
a.If 000.00= ON Then System Traffic Light is Active.
Green Light in Position A = ON
b.If 000.00= ON And ( 010.00 = ON or TIM003 = ON ) And 010.02 = OFF Then 010.01 = ON ( Hold ON ) And TIM000 Activated.
Green Light in Position C = ON
c.If 000.00= ON And TIM000= ON And 010.03 = OFF Then 010.02 = ON ( Hold ON ) And TIM001 Activated.
Green Light in Position D = ON
d.If 000.00= ON And TIM001= ON And 010.04= OFF Then 010.03= ON ( Hold ON ) And TIM002 Activated.
Green Light in Position B = ON
e.If 000.00= ON And TIM002= ON And 010.01= OFF Then 010.04= ON ( Hold ON ) And TIM003 Activated.
f.If TIM003= ON And Goto Step 1.a.

Step 2 :
Sequence for Red Light
a.If 000.00= ON And ( 010.02 = ON Or 010.03 = ON Or 010.04 = ON ) Then 010.05 = ON.
b.If 000.00= ON And ( 010.01 = ON Or 010.02 = ON Or 010.03 = ON ) Then 010.06 = ON.
c.If 000.00= ON And ( 010.01 = ON Or 010.03 = ON Or 010.04 = ON ) Then 010.07 = ON.
d.If 000.00= ON And ( 010.01 = ON Or 010.02 = ON Or 010.04 = ON ) Then 010.08 = ON.

Step 3 : Output PLC
a.If 000.00= ON And 010.05 = ON Then 005.00 = ON.
b.If 000.00= ON And 010.01 = ON Then 005.01 = ON.
c.If 000.00= ON And 010.06 = ON Then 005.02 = ON.
d.If 000.00= ON And 010.04 = ON Then 005.03 = ON.
e.If 000.00= ON And 010.07 = ON Then 005.04 = ON.
f.If 000.00= ON And 010.02 = ON Then 005.05 = ON.
g.If 000.00= ON And 010.08 = ON Then 005.06 = ON.
h.If 000.00= ON And 010.03 = ON Then 005.07 = ON.
