Legend for Detail Conveyor Control Using PLC :
1. Conveyor Belt
2. Infrared Sensor
3. Push Button Start (Normally Open Contact)
4. Push Button Stop (Normally Closed Contact)
--- Link : normally open normally closed contact
5. Potentiometer Speed Controller
6. Empty Lightbox
7. PLC (Programmable Logic Controller)
8. Inverter for Speed Control of Motor
--- Link : motor inverter wiring diagram
9. Electric Motor
10. Belt and Pulley Systems
PLC Input and Output Devices :
1. PLC Input :
<-> 1 Input Unit for Infrared Sensor
<-> 1 Input Unit for Push Button Start
<-> 1 Input Unit for Push Button Stop
--> Total PLC Input, minimum of 3 Input.
2. PLC Output :
<-> 1 Output Unit for Empty Lightbox
<-> 1 Output Unit for Start-Stop on Inverter
--> Total PLC output, minimum of 2 Output.
Sequence PLC Programming for Conveyor Control :
1. Conveyor Start
a. If Push Button Start = ON Then Output Unit for Start-Stop on Inverter = ON (Hold ON)
2. Conveyor Stop
a. If Push Button Stop = OFF Then Output Unit for Start-Stop on Inverter = OFF
b. If Infrared Sensor = ON Then Output Unit for Start-Stop on Inverter = OFF Else Output Unit for Start-Stop on Inverter = ON
3. Empty Lightbox = ON
a. If Output Unit for Start-Stop on Inverter = ON AND Infrared Sensor = OFF AND Wait For 10 Seconds Then Empty Lightbox = ON Else Empty Lightbox = OFF
