WIA网络与MODBUS网络互联设计与实现

本文首先介绍了WIA技术和Modbus协议的基本原理和结构,然后详细介绍了互联过程中使用的两种方式:透明传输方式和协议转换方式。分析了两种方式的适用范围和改造难度,并给出了实现案例。

The paper introduced a design of WIA-PA networks connected with Modbus networks.Firstly,we introduced the WIA technology and the basic principle and structure of Modbus protocol,and then described two ways which were used in the internet in detail:transparent transmission and protocol translation.In addition,the scope of application and the difficulty of transformation were taken into consideration with the demonstration of suitable cases.
