Quantum系列PLC与上位机的以太网通信研究
The Research about Ethernet Communication between Computer and Quantum PLC
【摘要】 本文以 Modbus 协议为应用层协议,TCP 为传输层协议,IEEE802.3为介质访问控制协议,结合 VB 里的 Winsock 控件,编制了Modbus/TCP 通信程序,实现了 Quantun 系列 PLC 与上位机的以太网通信。该程序具有通信速度快,可靠性高的特点。
【Abstract】 A Mobdus/TCP communication model is presented in the paper,it is programmed by VB,and the Winsock control is used in the program. The application layer uses modbus protocol,the transmission layer uses TCP and the Media Access Control protocol uses IEEE802.3 standard.This program has advantages such as high speed and high reliability.
