Reading Ladder PLC Programming for Filling Machine :
Step 1 :
a.If 0000 = ON And 0001 = OFF And 0015 = ON And 0100 = ON Then 1200 = ON And 1201 = Momentary ON ( Diff. Up).
b.1201 For Return To Origin Signal
c.If 1200 = ON Then ALL System Ready ( Master Control = ON ).
Step 2 :
For Pump ON and Drain Process for 1 Nozzle, Example Nozzle 1
a. If 0002 = ON And 1300 = OFF Then 1000 = ON.
b. If 0511 = ON And 0507 = OFF Then 1004 = ON.
c. If 0511 = ON And 0503 = ON And 0010 = OFF Then T000 Activated ( Can be Setting for Stability ).
d. If T000 = ON Then SET 1300 = Hold ON.
e. If 0002 = OFF Then RES 1300 = OFF.
See Picture for Setting Stability Flow Switch OFF :
Setting Stability Flow Switch for PLC Keyence
Step 3 :
Filling Process
a. If (0511 = ON And 0006 = ON) Or (0512 = ON And 0007= ON) Or (0513 = ON And 0008= ON) Or (0514= ON And 0009= ON) Then 1008 = ON.
b. If 1008 = ON And 0102 = ON And 0500 = OFF And 1109 = OFF Then 1009 = ON (Latching ON) And 1010 = Momentary ON ( Diff. Up).
c. If 1010 = ON And 1106 = OFF And 1009 = ON Then 1011 = ON (Latching ON).
d. If 1011 = ON And 0101 = ON And 1106 = OFF And 1009 = ON Then 1012 = ON (Latching ON).
e. If 1012 = ON And 0511 = ON And 0006 = ON And 1101 = OFF Then 1013 = ON And T004 Activated ( Can be Setting for Liquid Volume ).
f. If 1012 = ON And T004 = ON Then SET 1101 = Hold ON ( Bottle 1 = FULL ).
g. If 1101 = ON And 1102 = ON And 1103 = ON And 1104 = ON Then 1105 = ON ( ALL Bottle = FULL ).
See Picture for Setting Liquid Volume for Bottle 1 until 4 :
Setting Liquid Volume in the Bottle
Step 4 :
Nozzle Up
a. If 1010 = ON Or 1106 = ON Then 1101 = OFF And 1102 = OFF And 1103 = OFF And 1104 = OFF.
b. If 1012 = ON And 1105 = ON And 1107 = OFF Then 1106 = ON (Latching ON).
Step 5 :
Running Screw Conveyor
a. If ( 1106 = ON Or 1111 = ON ) And 0102 = ON And 1108 = OFF Then 1107 = ON (Latching ON).
b. If 0500 = ON Then C010 Activated Count Up to 4 ( Not Set ).
c. If C010 = ON Then 1107 = OFF.
d. Continue To Step 3
Step 6 :
Return to Origin
a. If 1201 = ON And 0102 = OFF Or ( 0006 = OFF And 0007 = OFF And 0008 = OFF And 0009 = OFF ) Then 1109 = ON (Latching ON).
b. Nozzle move to Up
c. If Bottle Empty Then Running Screw Conveyor
