MMS는 통신망으로 연결된 자동화기기와 컴퓨터 응용 프로그램간에 실시간 데이터와 감시제어정보를 교환하기 위한 국제표준의 메시지 교환 규약으로, MMS는 실행되는 응용기능의 종류나 기기의 개발자에 관계없이 표준적인 방법으로 정보를 교환하게 한다. MMS에서 제공되는 서비스들은 각종의 자동화기기와 응용 프로그램, 또한 여러 산업현장에서 필요로 하는 기능을 모두 만족하기에 충분하다. 그리고 MMS는 자동화된 생산공정을 구성하거나 사용하는데 필요한 경비를 줄여준다. MMS는 다양한 자동화 기기간의 통신을 하나의 통일된 규약과 방법론을 사용하여 이루고자 할 때 상호운용성(Interoperability), 독립성(Independence), 데이터접근(Data Access)성 등의 특징을 가장 잘 발휘할 수 있다.

최근 반도체 장비는 충분한 네트워크 성능과 유지 관리 기능을 자체적으로 내장하고 있으며, 자동화 네트워크 구성을 위한 통신규약 및 메시지로 SECS-I, SECS--II, HSMS와 PLC장비의 OPC등이 있다. 하지만 각 통신규약 및 메시지 형태가 상이하여 통합 관리 및 모니터링이 어려운 실정에 있다. 따라서 본 논문에서는 반도체 산업장비의 다양한 통신규약중 사용도가 높은 SECS-II와 OPC에서 메시지를 추출하고 통합된 메시지를 작성하기 위한 방법 및 소프트웨어 구조를 제시한다. 이러한 시스템을 통해서 생산 효율 및 가동률을 높이고, 고장 진단/장애요소 제거 등 산업 현장에서 발생할 수 있는 문제점을 개선 할 수 있는 기반 기술을 마련한다.

In this paper, an interface method for MMS on ATM networks is proposed. It can apply to the realtime communication and the remote control in wide-area manufacturing complex and virtual factory. It is used for the downloading program, the reporting and gathering of data and the remote control for the remote client. The developed interface rule is basd on the rule for MMS on TCP/IP. The main goals of implementation are to verify whether MMS on ATM is able to meet the requirements of factory automation and manufacturing complex.

Manufacturing devices must be integrated for constructing CIM environment, but integration of heterogeneous system meets several economical and technological difficulties. In this case, MMS(Manufacturing Message Specification) can be an effective method, but it has problems which MMS products are generally very expensive and majority of the existing manufacturing devices do not support MMS. This paper describes the development of a gateway for Non-MMS-Compatible CNC machine tools to serve MMS and the implementation of OSI(Open System Interconnection) upper layer on TCP/IP. The developed system is applied to construct cell controller with heterogeneous devices under CIM environment and to evaluate interoperability and portability.

The background of appearing MMS is to cope with the difficulty that occurred in constructing CIM with multi-vendor production devices such as CNC, PLC and robot. But so far the popularized use of MMS service in machine shop is not generalized because of economical and environmental reason. In this paper to solve this problem the CNC_VMD gateway for 3 types of heterogeneous machine tools in which MMS support is not available is developed and its performance is evaluated in shop floor having CIM environment. The developed VMD has the functions such as MMS service, driver for CNC interface and supporting for network. Non-MMS compatible machine tool can be MMS-compatible by using the developed gateway with CNC_VMD.

Cim realization for the machinery manufacturing plant has several problems such as a lack of the adaptibity for system integration of the production machines, a lack of the flexibility for the information flow and a lack of the interchangeability fot the variety of the interchange information. In the paper the development of VMD for the object oriented machine tool in Cim enviroment is accomplised. FOr this purpose VMD is constructed in PC with NT 3.51/OS enviroment by using the exculsive comunication board and PLC for the conventional CNC machine tool that VMD support is not available. And also RS232 interface between VMD and CNC's and DNC 2 comunication board supplied by FANUC for two types of CNC are used. This developed VMD is very useful for CIM construction in the shop floor having the multi-vendor CNC controllers.
