Abstract:

PCs were communicatied with each other in the EPL network constructed by software programming.EPL packets were obtained by Wireshark software.Through the analysis of these packets,three stages of network boot-up procedure which were MN initialization stage、MN guiding CN boot-up stage and EPL cycle stage could be observed.NMT state machine and DLL state machine were also verified to be logical and accurate.This research can be used for reference by people who are interested in improving EPL protocol or using EPL equipment.

Key words: communication technology, ethernet powerlink(EPL), real-time ethernet(RTE), network management(NMT) state machine, data link layer(DLL) state machine
