Parser of industrial Ethernet EtherCAT based on XML

The technology and realization method of industrial Ethernet EtherCAT parser based on extensible markup language (XML) were studied. The format of EtherCAT datagram was introduced. The structure of Ethernet probe and parser was analyzed. A method of protocol datagram description based on XML was proposed to deal with the problem that common Ethernet parsers are limitative in the applications of industrial Ethernet. Then an open and reconfigurable industrial Ethernet parser was designed. Performance test of the method of protocol datagram description and open parser was carried out. The implementation shows that the method of protocol datagram description based on XML can describe EtherCAT datagram clearly, and the open industrial Ethernet parser can parser EtherCAT datas. Users can define, modify and extend parsing rules according to the protocol object format, and obtain clear display of the protocol telegram.
