PLC Mitsubishi Programming for Filling Machine


Reading Ladder PLC Programming for Filling Machine :
Step 1 :
a.If X000 = ON And X001 = OFF And X017 = ON And X020 = ON Then M32 = ON And M33 = Momentary ON ( Pulse ).
b.M33 For Return To Origin Signal
c.If M32 = ON Then ALL System Ready ( Master Control M100 = ON ).
Step 2 :
For Pump ON and Drain Process for 1 Nozzle, Example Nozzle 1
a. If X002 = ON And M48 = OFF Then M0 = ON.
b. If Y013 = ON And Y007 = OFF Then M4 = ON.
c. If Y013 = ON And Y003 = ON And X012 = OFF Then T0 Activated ( Can be Setting for Stability ).
d. If T0 = ON Then SET M48 = Hold ON.
e. If X002 = OFF Then RST M48 = OFF.
See Picture for Setting Stability Flow Switch OFF :

Step 3 :
Filling Process
a. If (Y013 = ON And X006 = ON) Or (Y014 = ON And X007= ON) Or (Y015 = ON And X010= ON) Or (Y016= ON And X011= ON) Then M8 = ON.
b. If M8 = ON And X022 = ON And Y000 = OFF And M25 = OFF Then M9 = ON (Latching ON) And M10 = Momentary ON ( Pulse).
c. If M10 = ON And M22 = OFF And M9 = ON Then M11 = ON (Latching ON).
d. If M11 = ON And X021 = ON And M22 = OFF And M9 = ON Then M12 = ON (Latching ON).
e. If M12 = ON And Y013 = ON And X006 = ON And M17 = OFF Then M13 = ON And T4 Activated ( Can be Setting for Liquid Volume ).
f. If M12 = ON And T4 = ON Then SET M17 = Hold ON ( Bottle 1 = FULL ).
g. If M17 = ON And M18 = ON And M19 = ON And M20 = ON Then M21 = ON ( ALL Bottle = FULL ).
See Picture for Setting Liquid Volume for Bottle 1 until 4 :

Step 4 :
Nozzle Up
a. If M10 = ON Or M22 = ON Then M17 = OFF And M18 = OFF And M19 = OFF And M20 = OFF.
b. If M12 = ON And M21 = ON And M23 = OFF Then M22 = ON (Latching ON).
Step 5 :
Running Screw Conveyor
a. If ( M22 = ON Or M27 = ON ) And X022 = ON And M24 = OFF Then M23 = ON (Latching ON).
b. If Y000 = ON Then C10 Activated Count Up to 4 ( Not Set ).
c. If C10 = ON Then M24 = OFF.
d. Continue To Step 3
Step 6 :
Return to Origin
a. If M33 = ON And X022 = OFF Or ( X006 = OFF And X007 = OFF And X010 = OFF And X011 = OFF ) Then M25 = ON (Latching ON).
b. Nozzle move to Up
c. If Bottle Empty Then Running Screw Conveyor
