This paper proposes a controller area network (CAN) controller design for monitoring the state of a programmable logic controller (PLC) system and predicting its failure. The PLC system is the main device used in production automation equipment based on a large amount of sensor data. The proposed controller collects and stores the status data of multiple PLCs and sensors, and sends the collected data to the host system through the CAN interface. Then, the host system analyzes the transmitted data and predicts whether the PLC system will fail. Moreover, the host system informs the user of the risk of system failure. The proposed controller is composed of a processor block and CAN communication module. It was tested by connecting a PLC device. Consequently, a diagnostic message was received per a period of 500 ms.
