Abstract: To effectively expand of industrial communication protocols to the underlying device networking and solve real‐time
problemsinindustrialcontrolfields,adesign ideawas proposed.ARM chips was used as hardware platform,Linux operating
systemswas used as a software platform, the combination provided the processing environment for POWERLINK real‐time
Ethernet rotocol stack,DM9000 Ethernet chipwas externally plugged to realize the physical layer functions of POWERLINK
p
protocolstack.Resultsof thecommunicationdatapacketcaptureexperimentsusingWiresharksoftwareandthatof testsoncom‐
municationsbetween master/slave protocol sites demonstrate the feasibility of this approach, which provides a viable way to
expandPOWERLINK protocol to theindustrialfield.
