Requirements for Distributed Monitoring and Control Networks (DMCN) differ greatly from those of typical data networks. Specifically, any DMCN technology which employs a fieldbus protocol is different from If network protocol TCP/IP. In general, one needs to integrate fieldbus protocol and TCP/IP to realize DMCN over IP network or internet Interoperability between devices and equipments is essential to enhance the quality and the performance of predictive maintenance (PM). This paper suggests a basic framework for LonWorks-based DMCN over IP network and a method to guarantee interoperability between devices and equipments.

Requirements for Distributed Monitoring and Control Networks(DMCN) differ greatly from those of typical data networks. Specifically, my DMCN technology which employs a filedbus protocol is different from IP network protocol TCP/IP. In general, one needs to integrate fieldbus protocol and TCP/IP to realize DMCN over IP network or internet, which can be viewed as Virtual Device Network(VDN). Interoperability between devices and equipments is essential to enhance the quality and the performance of predictive maintenance(PM). This paper suggests a basic framework for VDN using DMCN over IP network and a method to guarantee interoperability between devices and equipments.

웹기반 예지보전 (Predictive Maintenance)은 가상 디바이스 네트워크를 필요로 한다. 가상 디바이스 네트워크는 반드시 분산형 감시 및 제어 네트워크를 통해서만 구현될 수 있다. 일반적으로 분산형 감시 및 제어 네트워크를 인터넷 상에서 구현하려면 TCP/IP와 필드버스 프로토콜의 통합이 필요하다. 이 경우, 예지보전의 성능을 극대화하기 위해서는 기기간의 통신 호환성이 절대적으로 필요하다. 본 논문에서는 가상 디바이스 네트워크의 통신 특성을 분석하고 이를 토대로 분산형 감시 및 제어 네트워크를 활용한 웹기반 예지보전의 기본 틀을 제시한다.

Web-based virtual machine/manufacturing system (VMS) utilizes Virtual Device Network (VDN.) VDN inevitably involves the implementation of Distributed Monitoring and Control Networks (DMCN). In general, one needs to integrate device (control) network and IP network to realize DMCN over IP network or internet, which can be viewed as a VDN. In this study, LonWorks networking technology is used for device network and the transmission characteristics of LonWorks/IP-based VDN is investigated. A method to minimize the transmission delay in the LonWorks/IP networks is also suggested.
