Modbus现场总线的应用及故障分析

Application and Fault Analysis Based on Modbus Fieldbus

现场总线是一种全数字、多节点的先进通讯方式,仅需一对传输线即可通讯,而通讯线路堵塞引起的故障在实际生产中已越来越不可忽视.重点介绍了Modbus现场总线技术在陕西咸阳商业储备库电动阀通讯中的应用,结合经验,对常见的基于Modbus现场总线的通讯故障提出分析和解决方案.

:Fieldbus is an all-digital,multi-node advanced communication method.It only needs a pair of transmission lines to communicate,and the fault caused by communication line blockage has become more and more important in actual production.The application of modbus fieldbus technology in the electric valve communication of Xianyang commercial reserve in Shaanxi is introduced.Combined with the experience of maintenance personnel,the common modbus fieldbus-based communication faults are analyzed and solved.
