摘要
工业以太网中Modbus/TCP已经成为以太网通信行业事实上的标准。本文对该通信标准进行深入的研究并进行改进,提出在UDP/IP协议上实施Modbus协议,随后从实时性和可靠性两个方面分析了Modbus/UDP协议栈的优点,然后结合实验室开发的一个测控终端组建测试系统对该协议栈进行实验检验。理论和实际表明:Modbus/UDP协议可操作性好容易实现、实时性和可靠性高,组网方便灵活。
As a protocol of indnstrial etheruet Modbns/TCP has become the real standard in communication industry. Modbus protocol based on UDP/IP is introduced with thorough researching and improving of Modbus/TCP in this paper. Subsequently we analyzed it＇s superiority from two aspects of real - time and reliability. Lastly there was a system used to test the protocol constructed with laboratory development project of embedded RTU. The results showed that Modbus/UDP has good operability, easy to implement, high real - time and reliability and flexible application.
