Number Of Inputs and Output PLC applied :
1. Number Of Inputs PLC is 7 Input :
--- 1 Unit Input for ON / OFF Selector Switch
--- 1 Unit Input for GO from Sensor 0
--- 1 Unit Input for NOGO from Sensor 0
--- 1 Unit Input for Limit Lifter UP
--- 1 Unit Input for Limit Lifter DOWN
--- 1 Unit Input for Work Sensor from Sensor 1
--- 1 Unit Input for Work Sensor from Sensor 2
--- Total Number Of Inputs PLC is Minimum 7 Input Unit
--- For Sensor 0 , 1 Unit sensor with 2 output ( 1 output for GO, 1 Output for NOGO )
--- Example Type Sensor 0 ( GO , NOGO ) : Thickness Detection Sensor
--- For Sensor 1 and Sensor 2 , 1 Unit Sensor with 1 Output.
--- Example Type Sensor 1 and 2 ( Goods Sensor ) : Goods Sensor or Proximity
2. Number Of Output PLC is 3 Output :
--- 1 Unit Output for Contactor. It's Functions to electrical Motor Conveyor ( ON / OFF Motor )
--- 1 Unit Output for Electrical Solenoid Type Center Closed. It's Functions to Moves Lifter DOWN
--- 1 Unit Output for Electrical Solenoid Type Center Closed. It's Functions to Moves Lifter UP
--- Total Number Of Outputs PLC is Minimum 3 Output Unit
Sequence PLC Programming for Sorter Machine :
Step 1 :
a. If Switch = ON And Sensor 0 (GO) = OFF And Sensor 0 (NOGO) = OFF Then Contactor for Motor Conveyor = ON.
b. If Switch = OFF or Sensor 0 (GO) = ON or Sensor 0 (NOGO) = ON Then Contactor for Motor Conveyor = OFF.
Step 2 :
a. If Switch = ON And Sensor 0 (GO) = ON and Limit Lifter UP = OFF Then Solenoid Lifter UP = ON.
b. If Switch = ON And Sensor 0 (GO) = ON and Limit Lifter UP = ON Then Solenoid Lifter UP = OFF.
c. If Switch = ON And Sensor 0 (NOGO) = ON and Limit Lifter DOWN = OFF Then Solenoid Lifter DOWN = ON.
d. If Switch = ON And Sensor 0 (NOGO) = ON and Limit Lifter DOWN = ON Then Solenoid Lifter DOWN = OFF.
Step 3 :
a. If Sensor 0 (GO) = ON And Limit Lifter UP = ON And Sensor 1 = OFF Then Contactor for Motor Conveyor = ON.
b. If Sensor 0 (NOGO) = ON And Limit Lifter DOWN = ON And Sensor 2 = OFF Then Contactor for Motor Conveyor = ON.
