PLC (Programmable Logic Controller) is one of the most important device in industrial automation nowadays. PLC is the device which control the machine so that the machine can run fully automatically. PLC is rarely use to control movement of the axis. Usually axis movement will be controlled by CNC (Computer Numeric Controller) machines. But in this Project, PLC is used to control gantry robot with three axis using positioning servo drive and its communicate via PROFIBUS (Process Fieldbus). The reason that PLC used to control the robot is because, PLC based machine is relatively much cheaper compare to machine that use CNC.
