Abstract:
Nowadays, the application of PLC is widely known and used in this digital world PLC’s application is obviously applied at the industrial sector. Normally, the PLC’s that have been used at the industrial field is usually to control a mechanical movement either of the machine or a heavy machine in order to create an efficient production and accurate signal processing. In this project, a discussion about PLC application will be explained in more details and specifically .Whereby, a machine that used to prepare automatically filling liquid into the bottle is fully controlled by the PLC Allen-Bradley [MicroLogix1200] ,which acts as the heart of the system. The system sequence of operation is designed by ladder diagram and the programming is done by using [RsLogix500] software. A Sensor usually plays its vital part as an input signal transmitter for the PLC in this system. During this project a sensor has been used to detect the bottle position while moving along the conveyor belt at the low speed and the machine is operating. The input signal that has been sent from the sensor to the PLC has being made as a reference signal in order to determine the output signal that exactly the same with the PLC programming language based on the user requirement , Another sensor is used to detect the level of liquid. Besides that, the electronics and electric devices are controlled by the PLC system like a motor, sensor, conveyor belt and the others devices.
