  • Fieldbus provides real-time data communication among field devices in the manufacturing automation and process control systems. In this study, an experimental model of fieldbus-based manufacturing automation system is developed. Experimental model consists of two robots, two conveyor belts, NC machine, PLC, sensors and operator station. These machines are interconnected into the Profibus network, and exchange their data through the services provided by FMS(Fieldbus Message Specification), which is the application layer protocol of Profibus. The experimental model is used to measure the network-induced delay of variable and file data transmitted through FMS services. Network-induced delays are collected and analyzed on each sublayer of Profibus protocol stack. The results obtained from the experiment of this study can be effectively utilized when fieldbus is implemented on the practical manufacturing automation systems.

  • A communication network protocol among programable devices built-i manufacturing field, MAP (Manufacturing Automation Protocol), has to provide the job transfer service carrying out a lot of jobs distributively, and the MMS( manufacturing message specification) defines the above application layer protocol. In this paper user software required in job transfer was implemented. So as to provide each service with compatibility and extension, each module was designed according to the functions. A method is selected in double-assigning their domain and program applicable even in complex process, which loads and proceeds several programs sequentially. In order to confirm the logical validity of the designed protocol, local applying test is accomplished for the application layer of response station. Modelling the job flow process, each serice module is verified with the I/O primitives.

  • In this paper, we implement the function of the IEEE802.2LLC(logical link control) sublayer one of the 7layers in MAP(manufacturing automation protocol), a standard communication protocol for manufacturing automation. With the assembly language we designed the class 3 function based on the IEEE standards and verified on the network adaptor hardware. In this experiment, we tested the function using the simplified variables considering that the retransmission value was chosen to be 1 and the life-time of the transmission variable infinite. According to the result of the service procedures, we confirmed that user data were transmitted to the corresponding station without any error.

  • PROFIBUS is an open industrial communication network for a wide range of application in manufacturing automation and process control systems. PROFIBUS-DP(Decentralized Peripherals) are mainly used to connect smart automation devices via a fast serial link. PROFIBUS-DP adopts master/slave mechanism for communication service. In this paper, we present an implementation method of the protocol stacks for the master station of PROFIBUS-DP.

  • 국내에서 공장자동화에 대한 관심이 증가하고 있으며, 이에 관한 개발이 활발하게 시도되고 있다. 특히, '제조업 혁신 3.0 전략'에 따라 중소기업의 제조 공장들에 대한 스마트화에 대한 관심이 급격히 증가하고 있다. 뿐만 아니라, 스마트 공장을 구축하기 위한 정책적, 기술적, 전략적 접근 방법을 모색하고 있다. 하지만 이와 같은 스마트 공장 또는 공장 자동화 시스템을 도입하기 위해서는 제조 공장이 갖는 보안 취약점과 개인정보 보호 문제는 반드시 선결해야만 한다. 그러므로 우리는 공장 자동화를 위해서 가장 많이 도입되고 있는 무선 통신 기술인 RFID 통신 프로토콜에 적용 가능한 경량 암호 프로토콜을 제안한다. 본 논문에서 제안한 경량 암호 프로토콜은 기존의 공개키 기반 시스템이나 대칭키 암호 알고리즘과 비교해서 연산 횟수가 적고 처리 속도가 빠르다. 뿐만 아니라 낮은 전력 소비량과 저장 공간을 소비하도록 설계하였다.
