Step 1 :
a.If M17 = Pulse ON Then M11 = ON .
Request from Inside the Elevator
b.If X001 = ON And X004 = ON Or X005 = OFF Then M0 = ON (Hold ON) .
c.If X003 = ON And X005 = ON Or X004 = OFF Then M1 = ON (Hold ON) .
Request from Outside the Elevator
d.If X000 = ON And X005 = OFF Then M2 = ON (Hold ON) .
e.If X002 = ON And X004 = OFF Then M3 = ON (Hold ON) .
Step 2 :
Elevator doors open and close
a.If X004 = ON Then M4 = Pulse ON.
b.If X005 = ON Then M5 = Pulse ON.
c.If M4 = ON Or M5 = ON And M13 = ON And M14 = OFF And M7 = OFF Then M6 = ON (Hold ON).
d.If M6 = ON And X006 = ON And M10 = OFF Then M7 = ON (Hold ON).
e.If M7 = ON And X010 = ON And M9 = OFF Then M8 = ON.
f.If M7 = ON And X010 = OFF Then M9 = ON.
g.If M7 = ON And X005 = ON And ( X000 = ON Or X001 = ON ) Then M9 = ON.
h.If M7 = ON And X004 = ON And ( X002 = ON Or X003 = ON ) Then M9 = ON.
i.If M7 = ON And X007 = ON And M11 = OFF And M12 = OFF Then M10 = ON (Hold ON).
Step 3 :
Elevator moving up and down
a.If M10 = ON And ( M0 = ON And M2 = ON ) And X005 = OFF And M12 = OFF Then M11 = ON (Hold ON).
b.If M17 = ON Then M11 = ON (Hold ON).
c.If M10 = ON And ( M1 = ON And M3 = ON ) And X004 = OFF And M11 = OFF Then M12 = ON (Hold ON).
Step 4 : Output PLC
a.If M11 = ON Then Y000 = ON.
b.If M12 = ON Then Y001 = ON.
c.If M6 = ON Or M9 = ON Then Y002 = ON.
d.If M8 = ON Then Y003 = ON.
e.If M0 = ON Or X001 = ON Then Y004 = ON.
f.If M1 = ON Or X003 = ON Then Y005 = ON.
g.If M2 = ON Or X000 = ON Then Y006 = ON.
h.If M3 = ON Or X002 = ON Then Y007 = ON.
Step 5 : If no person in the elevator
a.If M10 = ON And M11 = OFF And M12 = OFF And X000 = ON And X005 = ON Then M13 = Diff. Up ON.
b.If M13 = ON Then M10 = OFF And M6 = ON.
c.If M10 = ON And M11 = OFF And M12 = OFF And X002 = ON And X004 = ON Then M14 = Diff. Up ON.
d.If M14 = ON Then M10 = OFF And M6 = ON.
