摘要
本文迎合PLC应用网络化发展的需求,提出一种基于嵌入式的Modbus RTU转Modbus TCP协议转化的通讯模块设计方法。该设计能简单、低成本、便捷、可靠的把现有支持Modbus RTU协议的PLC应用于以太网互联。
This article meets the requirement of the applicable network development, puts forward a communication module design method based on embedded Modbus RTU turns Modbus TCP protocol conversion. The design is simple, low cost, convenient and make PLC of existing support Modbus RTU protocol uses in Ethernet interconnect reliably.
