Step 1 : Process 1
a.If X000 = ON Then M0 = Momentary ON ( Pulse ).
b.If X000 = ON And M0 = ON And M2 = OFF And M3 = OFF Then M1 = ON ( Hold ON ).
c.If X000 = ON And M1 = ON And X005 = ON And X001 = ON Then SET M2 = ON ( Hold ON ).
d.If X000 = ON And M1 = ON And X005 = ON And X002 = ON Then SET M3 = ON ( Hold ON ).
e.If X000 = OFF Then RST M2 = ON ( M2 = OFF ) And RST M3 = ON ( M3 = OFF ).

Step 2 : Process 2 And 3
PROCESS 2 :
a.If X000 = ON And M3 = ON And X002 = ON And M5 = OFF And M6 = OFF Then M4 = ON ( Hold ON ).
b.If X000 = ON And M3 = ON And M4 = ON And X007 = ON Or X006 = ON And X003 = ON Then SET M5 = ON ( Hold ON ).
c.If X000 = ON And M3 = ON And M4 = ON And X007 = ON Or X006 = ON And X004 = ON Then SET M6 = ON ( Hold ON ).
PROCESS 3 :
d.If X000 = ON And M3 = ON And M6 = ON And X004 = ON And M8 = OFF And M9= OFF Then M7 = ON ( Hold ON ).
e.If X000 = ON And M3 = ON And M6 = ON And M7 = ON And X005 = ON Or X010 = ON And X001 = ON Then SET M8 = ON ( Hold ON ).
f.If X000 = ON And M3 = ON And M6 = ON And M7 = ON And X005 = ON Or X010 = ON And X002 = ON Then SET M9 = ON ( Hold ON ).
g.If X000 = OFF Then RST M5 = ON ( M5 = OFF ) And RST M6 = ON ( M6 = OFF ) And RST M8 = ON ( M8 = OFF ) And RST M9 = ON ( M9 = OFF ).

Step 3 : Output PLC
a.If X000 = ON And M1 = ON Then Y000 = ON.
b.If X000 = ON And M7 = ON Then Y001 = ON.
c.If X000 = ON And M4 = ON Then Y002 = ON.
d.If X000 = ON And M1 = ON Or M4 = ON Or M7 = ON Then Y003 = ON.
e.If X000 = ON And M1 = ON Or M7 = ON Then Y004= ON.
f.If X000 = ON And M4 = ON Then Y005 = ON.
