Reading Ladder PLC Programming for Elevator PLC Program with PLC Keyence :

Step 1 :
a.If 1101 = Diff. Up ON Then 1011 = ON .
Request from Inside the Elevator
b.If 0001 = ON And 0004 = ON Or 0005 = OFF Then 1000 = ON (Hold ON) .
c.If 0003 = ON And 0005 = ON Or 0004 = OFF Then 1001 = ON (Hold ON) .
Request from Outside the Elevator
d.If 0000 = ON And 0005 = OFF Then 1002 = ON (Hold ON) .
e.If 0002 = ON And 0004 = OFF Then 1003 = ON (Hold ON) .

Step 2 :
Elevator doors open and close
a.If 0004 = ON Then 1004 = Diff. Up ON.
b.If 0005 = ON Then 1005 = Diff. Up ON.
c.If 1004 = ON Or 1005 = ON And 1013 = ON And 1014 = ON And 1007 = OFF Then 1006 = ON (Hold ON).
d.If 1006 = ON And 0006 = ON And 1010 = OFF Then 1007 = ON (Hold ON).
e.If 1007 = ON And 0008 = ON And 1009 = OFF Then 1008 = ON.
f.If 1007 = ON And 0008 = OFF Then 1009 = ON.
g.If 1007 = ON And 0005 = ON And ( 0000 = ON Or 0001 = ON ) Then 1009 = ON.
h.If 1007 = ON And 0004 = ON And ( 0002 = ON Or 0003 = ON ) Then 1009 = ON.
i.If 1007 = ON And 0007 = ON And 1011 = OFF And 1012 = OFF Then 1010 = ON (Hold ON).

Step 3 :
Elevator moving up and down
a.If 1010 = ON And ( 1000 = ON And 1002 = ON ) And 0005 = OFF And 1012 = OFF Then 1011 = ON (Hold ON).
b.If 1101 = ON Then 1011 = ON (Hold ON).
c.If 1010 = ON And ( 1001 = ON And 1003 = ON ) And 0004 = OFF And 1011 = OFF Then 1012 = ON (Hold ON).

Step 4 : Output PLC
a.If 1011 = ON Then 0500 = ON.
b.If 1012 = ON Then 0501 = ON.
c.If 1006 = ON Or 1009 = ON Then 0502 = ON.
d.If 1008 = ON Then 0503 = ON.
e.If 1000 = ON Or 0001 = ON Then 0504 = ON.
f.If 1001 = ON Or 0003 = ON Then 0505 = ON.
g.If 1002 = ON Or 0000 = ON Then 0506 = ON.
h.If 1003 = ON Or 0002 = ON Then 0507 = ON.

Step 5 : If no person in the elevator
a.If 1010 = ON And 1011 = OFF And 1012 = OFF And 0000 = ON And 0005 = ON Then 1013 = Diff. Up ON.
b.If 1013 = ON Then 1010 = OFF And 1006 = ON.
c.If 1010 = ON And 1011 = OFF And 1012 = OFF And 0002 = ON And 0004 = ON Then 1014 = Diff. Up ON.
d.If 1014 = ON Then 1010 = OFF And 1006 = ON.
