Industrial Automation for Assembly Line with PLC

Number Of Inputs and Output PLC applied :
1. Number Of Inputs PLC is 13 Input :
--- 5 Unit Input for Push Button Emg / Emergency.
--- 5 Unit Input for Push Button Finish.
--- 2 Unit Input for Sensor 1 and Sensor 2.
--- 1 Unit Input for sensor 3. It's Function to Count Revolution or Distance Between Operators.
--- Total Number Of Inputs PLC is Minimum 13 Input Unit.

--- Example Push Button : Devices Input PLC
--- Example Sensor 1 and Sensor 2 : Sensor / Proximity

2. Number Of Output PLC is 16 Output :
--- 1 Unit Output for Contactor. It's Functions to electrical Motor Conveyor ( ON / OFF Motor )
--- 5 Unit Output for Emg / Emergency Lamp or Tower / Sign Lamp Red
--- 5 Unit Output for Finish Lamp or Tower / Sign Lamp Yellow
--- 5 Unit Output for Proses Lamp or Tower / Sign Lamp Green
--- Total Number Of Outputs PLC is Minimum 16 Output Unit

--- Example Tower / Sign Lamp : Devices Output PLC

Sequence PLC Programming for Assembly Line :

Step 1 :
If Push Button Emg Operator 1 = OFF Or Push Button Emg Operator 2 = OFF Or Push Button Emg Operator 3 = OFF Or Push Button Emg Operator 4 = OFF Or Push Button Emg Operator 5 = OFF Then Contactor for Motor Conveyor = OFF And All System OFF.


Step 2 :
a. If Sensor 1 = ON And Sensor 2 = OFF And All Push Button Finish = ON Then Contactor for Motor Conveyor = ON.
b. If Count ( Sensor 3 = ON ) = 2 ( Data Setting for Distance Between Operators ) Then Contactor for Motor Conveyor = OFF.


Step 3 :
a. If Push Button Emg = OFF Then Tower / Sign Lamp Red = ON.
b. If Push Button Finish = ON And Push Button Emg = ON Then Tower / Sign Lamp Yellow = ON.
c. If Sensor 1 = ON And Push Button Emg = ON Then Tower / Sign Lamp Green Operator 1 = ON.
d. If Count ( Motor Conveyor = ON , Motor Conveyor = OFF ) > 1 And Motor Conveyor = OFF And Push Button Emg = ON And Sensor 2 = OFF Then Tower / Sign Lamp Green Operator 2 = ON.
e. If Count ( Motor Conveyor = ON , Motor Conveyor = OFF ) > 2 And Motor Conveyor = OFF And Push Button Emg = ON And Sensor 2 = OFF Then Tower / Sign Lamp Green Operator 3 = ON.
f. If Count ( Motor Conveyor = ON , Motor Conveyor = OFF ) > 3 And Motor Conveyor = OFF And Push Button Emg = ON And Sensor 2 = OFF Then Tower / Sign Lamp Green Operator 4 = ON.
g. If Sensor 2 = ON And Push Button Emg = ON Then Tower / Sign Lamp Green Operator 2, 3, 4, 5 = ON.
