This paper proposes a new design and implementation of multi-protocol IED for networked control system of multi-induction motor in industrial fields. The experimental multi-induction motor based multi-protocol IED of Modbus/LonTalks/TCP/IP module is designed and fabricated. This article addresses issues in architecture of LonWorks/Ethernet sever, embedded processors architecture for converting Modbus protocol to LonTalks protocol, integrating preconfigured software, and Internet technologies. It is also verified that the multi-induction motor control and monitoring system using LonWorks/Ethernet server have available, interoperable, reliable performance characteristics from the experimental results, especially, the seamless integration of TCP/IP networks with control networks allows access to any control point from anywhere. Thus, the results provide available technical data for remote distributed motor control system of industrial field or building microgrid with LonWorks BAS.

This paper proposes a new Web based-control concept & design method and implementation of LonWorks network system for a large scale renewable energy energy control and monitoring system in building. The Experimental LonWorks network system using LonWorks/Ethernet(Web) server is designed and fabricated. This article addresses issues in architecture of LonWorks/Ethernet sever, embedded processors architecture for converting LonTalks protocol to Modbus protocol and software, and Internet technologies. It is also verified that the multi-induction motor control and monitoring system using LonWorks/Ethernet server have available, interoperable, reliable performance characteristics from the experimental results, Especially, The seamless integration of TCP/IP networks with control networks allows access to any control point from anywhere. Thus, the results provide a available technical data for remote distributed control system of industrial and buildings field.

In recent years, the case to install small water treatment facility to every local area has increased. A key issue in the successful implementation of the control systems for the water treatment plants is the choice of control architecture. Within the framework of distributed control system(DCS), this paper presents a new development of intelligent control module and its novel application to open control architecture for water treatment plants. This control system so called NCS(Network Based Control System) with standard networks system with LonTalks protocol of ANSI/EIA 709.1, regulatory control function and information dispatch function has suitable functionality to operate these distributed water treatment facility effectively. This paper describes the case where NCS is applied for the filters system in water treatment facility of Heong Sung area.

빌딩자동제어시스템은 여러 서브시스템의 통합을 통한 고도의 서비스 제공, 관리비의 절감 등을 효과적으로 실현할 수 있다. 통합운전의 전제조건은 표준 프로토콜을 가진 개방형 네트워크를 이용하여 합리적인 네트워크 설계에 있다. 따라서 본 논문에서는 BAS에 가장 걸림돌이 되었던 화재경보시스템(소방법 명칭)을 ANSI/FIA 709.1인 LonTalk 프로토콜을 이용하여 BAS에서의 통합을 위한 개념적인 새로운 설계방안을 제시하였다. 기존 시스템에서 사용되는 중계기를 대체하는 지능형제어모듈을 개발하고 이를 이용하여 개방된 지능형 화재경보시스템의 설계방안을 제안한 것이다. 이는 오보률의 저감 실현은 물론 빌딩의 통합운전에도 크게 기여할 것으로 판단된다.
