1. Experiment # 11(Open Ended)
Automatic door open & close system using PLC
Objective:
To design and test the automatic door open & close using PLC.
Theory:
Implement logic for the automatic door open & close system in PLC using ladder diagram programming
language.
We will use PLC S7-300 for this application. Also we will use TIA portal software for programming.
In this system when someone enters the infrared sensing field, opening motor starts working to open the
door automatically till the door touches the door opening limit switch.
If the door touches the opening limit switch for 8sec and no body enters the sensing field/area, then
closing motor starts to close the door automatically till the door touches the closing limit switch.
Stop the closing action immediately if someone enters the sensing field during the door closing process.
