摘要
介绍了Modbus应用层协议在串行网络和以太网络中的通信方式,提出基于Modbus通信的泵站监控系统,分析了泵站采用Modbus通信的原因,并结合深圳沙湾泵站工程详细说明了系统主控层网络客户/服务器通信的实现,以及现控层网络主/从通信的实现。
The communication mode of Modbus application protocol in a serial line network and Ethernet is introduced. A modbus protocol-based monitoring and control system of pumping stations is put forward. The reason for adopting Modbus protocol is analyzed. With the Shenzhen Shawan Pumping Station as an example, the realization of client/server communication in the main control network and master/slave communication in the local control network is described in detail.
