Abstract

There are various networks and communication methods are used in industrial communication. Enterprises need to convert communications between industrial devices and networks for production line expansion, factory upgrades, network segmentation, and SI. This requires designers manufactured by many manufacturers to provide communication equipment for data or protocol conversion in order to connect and transmit various other mechanical devices to the network. This paper designed industrial communication gateway that can support the transformation of industrial communication protocol using multi-layered communication module. Industrial communication gateways have a structure that connects individual communication modules using RS485 communication to multiple layers. Each communication module consisted of analog and digital data card, LAN, and CAN-enabled card. The main board processor used Atmega micro-processor, and the RS485 slot was placed to have a multi-layer communication module structure. These additive layer type communication modules support analog and digital I/O functions and LAN and CAN for wide use in industrial communication control and monitoring.

산업 통신에는 다양한 네트워크가 있으며 여러 가지 통신 방식을 사용한다. 기업에서는 생산 라인 확장, 공장 업그레이드, 네트워크 세분화, 시스템 통합 등을 위하여 산업용 장치와 네트워크 간에 통신 변환이 필요하다. 이것은 많은 제조회사가 제작한 설계자가 다른 다양한 기계 장치를 네트워크에 연결하고 전송하기 위하여 데이터 또는 프로토콜 변환을 위한 통신 장비가 제공되어야함을 의미한다. 본 논문에서는 적층형 통신 모듈을 사용하여 산업 통신 프로토콜 변환을 지원할 수 있는 산업용 통신 게이트웨이를 설계하였다. 제작된 게이트웨이는 RS485 시리얼 통신을 이용하는 개별 통신 모듈을 다층으로 연결하는 구조를 가지고 있다. 각각의 통신 모듈은 아날로그 데이터 카드, 디지털 데이터 카드, CAN 및 LAN 지원 카드로 구성하였다. 메인 보드 프로세서는 Atmega micro-processor를 사용하였고, RS485 시리얼 슬롯을 배치하여 적층형 통신 모듈 구조를 가지도록 하였다. 본 논문에서 제작된 적층형 산업용 통신 게이트웨이는 아날로그 및 디지털 I/O 기능과 CAN과 LAN을 지원할 수 있기 때문에 산업용 통신 제어 및 모니터링에 폭넓게 활용될 수 있다.
