Detail Automatic Gates using PLC

Automatic Gates
Information on Drawing Numbers for Automatic Gates using PLC :
1. Area Sensor (If there are objects, the sensor output OFF)
2. Area Sensor (If there are objects, the sensor output OFF)
3. Area Sensor (If there are objects, the sensor output OFF)
4. Area Sensor (If there are objects, the sensor output OFF)
5. Electric Motor And Gearbox
6. Limit Switch for Open gate condition
7. Limit Switch for Closed gate conditions
8. Gate


Number Of Inputs and Output PLC applied :
1. Number Of Inputs PLC is 6 Input :
--- 4 Unit Input for Area Sensor 1,2,3,and 4.
--- 1 Unit Input for Limit Switch for Open gate.
--- 1 Unit Input for Limit Switch for Closed gate.
--- Total Number Of Inputs PLC is Minimum 6 Input Unit.

2. Number Of Output PLC is 2 Output :
--- 1 Unit Output to contactor for Electric Motor (Open Gate ).
--- 1 Unit Output to contactor for Electric Motor (Close Gate ).
--- Total Number Of Outputs PLC is Minimum 2 Output Unit.


Sequence PLC Programming for Automatic Gates :

1. Open Gate
a. If Area Sensor 1 = OFF Then Electric Motor for Open Gate = ON.
b. If Limit Switch for Open gate = ON Then Electric Motor for Open Gate = OFF.
c. Electric Motor for Close Gate = always OFF

2. Close Gate
a. If Area Sensor 4 = OFF AND Area Sensor 2 = ON AND Area Sensor 3 = ON Then Electric Motor for Close Gate = ON.
b. If Electric Motor for Close Gate = ON AND Area Sensor 2 = OFF OR Area Sensor 3 = OFF Then Electric Motor for Close Gate = OFF AND Electric Motor for Open Gate = ON.

Note : For All Area Sensor : If there are objects, the sensor output OFF
