碩士 === 南臺科技大學 === 電子工程系 === 105 === The Taiwan government began to promote industry 4.0 in 2016. This concept aims at the change of the production line which can meet the specific demand from the end customer. In this thesis, we will show the process of the realization of industry 4.0 using the CAN bus standard which is original applied in the automotive industry. Because of its reliability and low cost of communication, this protocol can be used to facilitate the integration of intelligent production using different equipments. CAN Bus is widely used in industrial control 4.0, e.g., CANopen, an industrial control protocol based on the CAN Bus. In this paper, the mechanism of CAN bus networking protocol will be introduced, which includes the evolution history, the signal characteristics of the Physical Layer and message framework of the Data Link Layer. The error detection and protection shemes will also be discussed. Starting from the understanding of CAN bus standard, we will show the capability of software CANoe, developed by Vector company, for the design of CAN bus module. Physically, the CS8959 chip developed by Myson is employed on the implementation of a CAN node. The CANopen CiA401standard is realized based on the CAN bus physical layer protocol. The main function of this CANopen node is a four-channel analog signal input for the sensing module. Experimental results show that temperature sensor (LM35), humidity sensor (HR202L) and photometric sensor (TEMT6000) are successfully implemented and integrated to a SCADA system in an automatic control environment.
