Reading Ladder PLC Programming for Parking Information using PLC Keyence :

Step 1 :
Setting Data equal capacity of parking areas
a.If 1100 = OFF Then DM0001 = 15.
Remarks :
a.1. If capacity of parking areas = 0 Then DM0001 = 10.
a.2. If capacity of parking areas = 5 Then DM0001 = 10 + 5 = 15.
a.3. If capacity of parking areas = 1000 Then DM0001 = 10 + 1000 = 1010.

Step 2 :
"FULL" display => ON
a.If 0000 = ON Then Increments the DM0000 by 1(one).
b.If DM0000 equal or more than 15 ( capacity of parking areas = 5 ) Then 1000 = ON.
c.If 1000 = ON Then 0500 = ON.

Step 3 :
"EMPTY" display => ON
a.If 0001 = ON Then Decrements the DM0000 by 1(one).
b.If DM0000 less than 15 ( capacity of parking areas = 5 ) Then 1001 = ON.
c.If 1001 = ON Then 0501 = ON.

Step 4 :
Minimum and Maximum Limits
Minimum Limits :
a.If DM0000 less than 10 ( LDB 1100 => LDA DM0000 => CMP #00010 => LD 2009 ) Then DM0000=10 ( DW #00010 DM0000 ).
Maximum Limits :
b.If DM0000 more than DM0001/capacity of parking areas ( LDB 1100 => LDA DM0000 => CMP DM0001 => LD 2011 ) Then DM0001=DM0000 ( LDA DM0001 => STA DM0000 ).
