**PLC Programming**for Weighing Machine using PLC Keyence :

**Step 1 :**

ALL Process ON/OFF

ALL Process ON/OFF

**a.**If 0000 = ON Then 1000 = ON (DIFU)

**b.**If 1000 = ON AND 0000 = ON AND 1009 = OFF Then 1001 = ON (ALL PROCESS ON)

**c.**If 0000 = OFF (ALL PROCESS OFF)

**d.**If 0001 = OFF AND 1002 = ON Then 1009 = ON ( ALL PROCESS OFF )

**Step 2 :**

Red Lights = OFF

Green Lights = OFF

Red Lights = OFF

Green Lights = OFF

**a.**If 1000 = ON AND 1001 = ON AND 1003 = OFF Then 1002 = ON

**b.**If 1002 = ON Then 1007 = OFF (RES 1007 = ON) AND 1008 = OFF ( RES 1008 = ON )

**c.**If 1007 = OFF Then 0502 = OFF (Green Lights = OFF)

**d.**If 1008 = OFF Then 0501 = OFF (Red Lights = OFF)

**Step 3 :**

Digital Zero Reset = ON

Digital Zero Reset = ON

**a.**If 1002 = ON AND T000 = ON AND 1001 = ON AND 1004 = OFF Then 1003 = ON

**b.**If 1003 = ON Then 0504 = ON (Digital Zero = ON)

**Step 4 :**

Rotary container = ON / OFF

Rotary container = ON / OFF

**a.**If 1003 = ON AND T001 = ON AND 1001 = ON AND 1005 = OFF Then 1004 = ON (Hold ON)

**b.**If 1004 = ON Then 0503 = ON (Electric Motor = ON)

**c.**If 0002 = OFF AND 1004 = ON AND 1001 = ON AND 1005 = OFF Then 1010 = ON (Check Sensor position = OFF)

**d.**If 1004 = ON AND 0503 = ON AND 1010 = ON AND 0002 = ON AND 1001 = ON AND 1006 = OFF Then 1005 = ON ( Electric Motor = OFF )

**e.**If 1005 = ON Then 1004 = OFF

**f.**If 1004 = OFF Then 0503 = OFF ( Electric Motor = OFF )

**Step 5 :**

Weighing : GO/OK = ON/OFF

Weighing : GO/OK = ON/OFF

**a.**If 1005 = ON AND T002 = ON AND 1007 = OFF AND 1008 = OFF AND 1001 = ON Then 1006 = ON (Judgment OK/NOT OK)

**b.**If 1001 = ON AND 1006 = ON AND 0003 = ON Then 1007 = ON (SET 1007 = ON) =>Weighing OK

**c.**If 1001 = ON AND 1006 = ON AND 0003 = OFF Then 1008 = ON (SET 1008 = ON) =>Weighing NOT OK

**d.**If 1007 = ON Then 0502 = ON (OK)

**e.**If 1008 = ON Then 0501 = ON (NOT OK)

**Step 6 :**

Empty Containers

Empty Containers

**a.**If 0001 = OFF AND 1002 = ON Then 1009 = ON (ALL PROCESS OFF)

**b.**If 0001 = ON Then 0500 = ON (Yellow Lights = ON)
