Abstract

The invention discloses a hardware implementing method for kernels of POWERLINK communication protocol master and slave stations. A data link layer, an application layer and a synchronous bus of the POWERLINK communication protocol master and slave stations are implemented on the basis of a programmable logic device and a customization / semi-customization hardware chip, wherein the data link layer comprises a master station and slave station data link layer controller, and the application layer comprises an application layer dial pulse receiver (DPR) and an application layer register (REG); each sub-module of the data link layer and the application layers DPR and REG are mounted on the synchronous bus; and the modules are integrated by integrated software, bit stream files are generated from codes by using implementing software, and the bit stream files are downloaded to target hardware to realize the kernels of the master and slave stations. Through the method, the kernels of the master and slave stations of a POWERLINK protocol are implemented in a complete hardware mode, the response speed of the kernels is improved from millisecond level of a central processing unit (CPU) to microsecond level of a digital logic circuit, and the real-time data processing burden of the master CPU is greatly lightened.

Description

technical field [0001] The invention relates to an implementation method of an industrial Ethernet communication protocol, in particular to a hardware implementation method of a master-slave station kernel of the POWERLINK communication protocol. Background technique [0002] POWERLINK is a communication protocol standard of real-time industrial Ethernet, which has high real-time performance in practical sense. POWERLINK defines a streamlined, highly real-time data link layer protocol, and defines CANopen as an application layer protocol. The POWERLINK protocol includes: communication description IEC61784-2; service and 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 reference model for many of today's common data-free priority transport protocols. This model divides the task of data transmission into 7 la...
