Abstract

The invention relates to the technical field of industrial Ethernet communication protocols, and discloses a POWERLINK communication protocol hardware realization method. In the embodiment of the invention, the method comprises steps: a data link layer and a physical layer interface of the POWERLINK communication protocol are realized based on any one chip selected from the following: a programmable logic device, a custom hardware chip and a semi-custom hardware chip; and the application layer of the POWERLINK communication protocol is realized based on any one mode selected from the following: a soft core processor, an embedded processor, and a general processor. POWERLINK master station equipment or slave station equipment obtained by adopting the realization method has a high data transmission response capability, high-speed and high-precision industrial field control requirements are met, the expansibility is more flexible, any object dictionary and any number of slave stations can be supported, the cost performance is good, and software and hardware are easy to realize and maintain.

Description

technical field [0001] The invention relates to the technical field of industrial Ethernet communication protocols, in particular to a hardware implementation method of the POWERLINK communication protocol. Background technique [0002] With the development of Ethernet technology and electronic information technology, the traditional fieldbus is developing in the direction of industrial Ethernet. POWERLINK was born under this background and was included in the international standards IEC61158 and IEC61784. POWERLINK conforms to the definition of real-time Ethernet in IEC61784. This protocol includes a real-time Ethernet data link layer and a CANOpen-based application layer. Its sub-protocol specifications include: communication description IEC61784-2; service protocol IEC61158-300, IEC61158-400 , IEC61158-500 and IEC61158-600; equipment description ISO15745-1. [0003] OSI is a communication model for the standardization of open information processing systems, and it is the...
