Abstract

The invention relates to the technical field of electronic communication and discloses a POWERLINK main station and a creation method thereof. The POWERLINK main station is based on a real-time operation system, and the real-time operation system is obtained by installing an Xenomai real-time kernel patch to a non real-time operation system Linux; in the POWERLINK main station based on the real-time operation system installed with the Xenomai real-time kernel patch, a driver interface of a bottom layer module, a driver interface of an event queue module and a driver interface of a user module of a top layer on a POWERLINK main station based on the non real-time operation system Linux are all replaced with Xenomai real-time driver interfaces, and the real-time driver interfaces are provided by a real-time driver module of the Xenomai real-time operation system; and the bottom layer module includes a network card driver module and a shared memory module. Compared with the prior art, the POWERLINK main station based on the real-time operation system installed with the Xenomai real-time kernel patch, provided by the invention, has the advantage that real-time communication between the POWERLINK main station and a slave station can be realized.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a POWERLINK master station and a creation method thereof. Background technique [0002] In the industrial control industry, the Linux operating system has attracted people's attention because of its free use. However, since the Linux operating system is non-real-time, when the POWERLINK master station is implemented on the Linux operating system, the real-time communication between the POWERLINK master station and the slave station cannot be realized. SUMMARY OF THE INVENTION [0003] The problem solved by the embodiments of the present invention is to provide a POWERLINK master station and a creation method thereof, so that the POWERLINK master station based on the real-time operating system patched with the Xenomai real-time kernel can realize the real-time communication between the POWERLINK master station and the slave station, and reduce the the cost of r...
