摘要
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.
