PLC Omron CJ1M CPU-21 Control Modification for Drill Oil Hole Machine in an Automotive Company

摘要

Abstract Nowadays, PLC (Programmable Logic Control) is one of the common controlling devices in machines in the industry, including the automotive industry. An automotive company in Indonesia that produces component motorized vehicles in the form of pistons using machines that controlled by PLC. Piston is one of the main automotive components in motor vehicles that play a role in the combustion process. In the order of making piston there is a process of making oil holes which is carried out using a Drill Oil Hole (DOH) machine. This machine currently uses on / off operation mode use push-button. In addition, there is no interface to display information needed by machine and maintenance operators. There are some modifications that will be made to the drive section to synchronize between the engine and the robot. This paper presents a review of the modification of DOH engine controls using the CPU-21 CJ1M Omron PLC with an interface in the form of a Human Machine Interface (HMI) to provide information and set data needed.
