I made a project on bottle filling. This project is mainly used in industries like coca cola , pepsi etc. In this project abottle takes 7 sec to be completely filled, if the filling is interrupted then it should resume from the same level. When the filling of one bottle is completed the motor should run for 2 sec for changing the bottle. i done the programming of this project with the help of PLC.
In this program we have used two inputs and two outputs of PLC i.e. I:0/0 & I:0/1 as inputs and O:0/0 & O:0/1 as outputs. We have used a RTO as timer and compare instructions LEQ and LIM. When input I:0/0 is ON the RTO will start and conveyor motor is started for 7 sec by using LEQ instruction and after 7 sec conveyor motor is stopped and then the valve is operated for 2 sec using LIM instruction. Then after 2 sec the conveyor motor again starts automatically.
