Reading Ladder PLC Programming for Parking Information using PLC Omron :

Step 1 :
Setting Data equal capacity of parking areas
a.If 10.00 = OFF Then D0 = 15, Instruction:MOV &15 D0
Remarks :
a.1. If capacity of parking areas = 0 Then D0 = 10, Instruction:MOV &10 D0.
a.2. If capacity of parking areas = 5 Then D0 = 10 + 5 = 15, Instruction:MOV &15 D0.
a.3. If capacity of parking areas = 1000 Then D0 = 10 + 1000 = 1010, Instruction:MOV &1010 D0.

Step 2 :
"FULL" display => ON
a.If I: 0.00 = ON Then Increments Pulse the D1 by 1(one), Instruction:@++ D1
b.If D1 equal or more than 15 ( capacity of parking areas = 5, Instruction:>= D1 D0 ) Then 10.01 = ON.
c.If 10.01 = ON Then Q: 100.00 = ON.

Step 3 :
"EMPTY" display => ON
a.If I: 0.01 = ON Then Decrements Pulse the D1 by 1(one), Instruction:@-- D1
b.If D1 less than 15 ( capacity of parking areas = 5, Instruction:< D1 D0 ) Then 10.02 = ON.
c.If 10.02 = ON Then Q: 100.01 = ON.

Step 4 :
Minimum and Maximum Limits
Minimum Limits :
a.If D1 less than 10 ( Instruction:< D1 &10 ) Then D1=10 ( Instruction:MOV &10 D1 ).
Maximum Limits :
b.If D1 more than D0/capacity of parking areas ( Instruction:> D1 D0 ) Then D0=D1 ( Instruction:MOV D0 D1 ).
