基于IEC60870-5-104远动规约的PLC：信模块的'计与实现
Design and implementation of PLC communication module based on IEC60870-5-104 protocol
摘要
Abstract
In order to apply the IEC 60870-5-104 telecontrol protocol , an Ethernet protocol for monitoring and controlling the substations or equipment in wide area to the field of industrial communication , this study analysed the structure of the IEC60870-5-104 telecontrol protocol , and presented a method for design and development of a PLC commu-nication module based on this protocol .The hardware platform of this communication module mainly includes the processer based on the ARM 7 kernel and Ethernet controller .The software platform uses the embedded real-time multi-task operating system to schedule the tasks of configuration file read , state feedback , module and PLC con-troller information exchange , data transformation according to the protocol request .The consistency , interoperabili-ty and system performance of the module were tested by experiments .The results showed that the communication module had the characteristics of independence , stability , strong interoperability , high reliability and so on .关键词
