Programmable Logic Controller (PLC) is a device which is consist of few relays that we can control it with a program. In their activity, human sometimes get tired and fed up with their work, so to handle this situation we need to create a system that can solve it. YNWK131 system is an automation system miniature that can move a material or object. It is controlled by PLC MELSEC-Q series from Mitsubishi. To get the desired function we have to design and create the mechanical parts and the software controller system. This YNWK131 parts are conveyor, moving arm, and infra red sensors which is in each process was controlled with PLC. On this project the PLC is used for controlling an automatic moving object. The programming device is using a ladder diagram with software GX-Developer ver.8. The program that has been made on the PC was written on PLC’s memory then saved in internal memory of PLC. We regulate the motor based on the flow chart then changed it into ladder and timing diagram. The system starts to work when IR1 sensor is detected an object on the leading edge of the conveyor. The conveyor start moving forward and the object is moved to the other side of the conveyor. The conveyor will stop after IR2 sensor is detected the object and the timer from PLC count for 2 seconds. The PLC timer is used for the compensation of infra red sensor pad thickness to get the right position for object before the arm push the object. The arm movement is powered by direct current motor. The software design was tested using MELSEC-Q training kit. From the mechanical parts, software and functional test result we can conclude that this device was working good according to the scope of the design. This system is wished can make a good contribution for PLC controller system development in the near future.
