Reading Ladder PLC Programming for Marking with Laser Engraving Machine :

Step 1 : Running / Stop
Running : a.If 0000 = ON Then SET 1000 = ON ( Hold ON ).
b.If 1000 = ON And 0505 = ON And 0006= ON And 0007 = OFF And 0000 = ON And 0002 = ON And 0004 = ON Then 1001 = ON ( Hold ON ) And 1002 = Momentary ON ( Diff. Up).
Stop : c.If 0001 = ON Then RES 1000 = ON ( 1000 = OFF ) And 1001 = OFF.

Step 2 :
Counter Reset To Laser Engraving Machine And Counter Reset in PLC a.If 1001= ON And 1002 = ON And T000 = ON Then 1003 = ON ( Hold ON ) And T000 Activated.
b.If 1003= ON Then RESET C003 And 0508 = ON ( Counter Reset To Laser Engraving = ON ).
c.If T000= ON Then 1003= OFF.

Step 3 : Automatic Marking Process
First Process of Marking ( Product 1 ) And Starts Marking a.If 1001 = ON And 1003 = ON And T000= ON And 1005 = OFF Then 1004 = ON ( Hold ON ).
The Next Process ( Product 2 until 5 ) And Continuous of Marking b.If 1001 = ON And 1014 = ON And 1005 = OFF Then 1004 = ON ( Hold ON ).
Waiting Process Marking from Laser Engraving Machine Completed c.If 1001 = ON And 1004 = ON And 0008= ON And 1006 = OFF Then 1005 = ON ( Hold ON ).
Retrieval Process of Product After in Marking d.If 1001 = ON And 1005 = ON And 0009= ON And 1007 = OFF Then 1006 = ON ( Hold ON ).
e.If 1001 = ON And 1006 = ON And 0005= ON And 1010 = OFF Then 1007 = ON ( Hold ON ).
f.If 1001 = ON And 1007 = ON And 0003= ON And 1012 = OFF Then 1008 = ON ( Hold ON ) And T001 Activated.
g.If T001= ON Then 1009 = Momentary ON ( Diff. Up) .
h.If 1001 = ON And 1008 = ON And 1009= ON And 1011 = OFF Then 1010 = ON ( Hold ON ).
i.If 1001 = ON And 1010 = ON And 0002= ON And 1012 = OFF Then 1011 = ON ( Hold ON ).
j.If 1001 = ON And 1011 = ON And 0004= ON And 1008 = ON Then 1012 = ON ( Hold ON ).
Counter PLC in adding one And Count-Up To Laser Engraving Machine = ON k.If 1001 = ON And 1012 = ON And T002= OFF Then 1013 = ON ( Hold ON ) And T002 Activated.
l.If 1013 = ON Then Count Up C003 ( For Count Product ).
m.If 1013 = ON Then 0507 = ON ( Count-Up To Laser Engraving Machine = ON ).
Counter PLC <> 5 ( C003= 5 ( Be Changed ) : Number of Products ) n.If 1001 = ON And T002 = ON And C003= OFF And 1004= OFF Then 1014 = ON ( Hold ON ) .
o.If 1014 = ON Then To Step 3.b Or The Next Process ( Product 2 until 5 ).

Step 4 : Origin Process
a.If 1001 = OFF And 0002 = OFF And 0000 = ON Then 0501 = ON.
b.If 1001 = OFF And 0002 = ON And 0004 = OFF And 0000 = ON Then 0503 = ON.
