Motion controller based on Profinet bus

Abstract

The invention discloses a motion controller based on a Profinet bus. The motion controller comprises a main board and a network card, the mainboard carries an operating system, and a programming toolis transplanted in the operating system and is used for packaging a process algorithm; one of the network cards serves as a Profinet master station for communication, and the IP address of an interface of the Profinet master station is mapped to a network card driver in the operating system. A programming tool is transplanted in an operating system carried by a mainboard, so that a client can package a process algorithm of the client into a motion controller, and an autonomous algorithm extension function is realized. Besides, the motion controller provided by the invention is based on the Profinet master station, and the IP address of the Profinet master station interface is mapped with the network card driver in the operating system, so that a client is supported to flexibly configure the Profinet while the servo driver, the frequency converter and the like can be controlled through the Profinet bus.

Description

Technical field[0001]This application relates to the field of industrial automation technology, and in particular to a motion controller based on Profinet bus.Background technique[0002]Large-scale motion controllers are an important part of industrial automation and industrial robot control systems. They can be used for servo control and IO control of industrial robots, CNC machine tools, and industrial automation production lines, and can be based on the actual production industry and operation timing in industrial applications. The servo driver and frequency converter output stable position, speed and torque, and realize the control of industrial automation production lines and industrial robots through reading and writing IO modules.[0003]In large-scale industrial automation solutions, each equipment manufacturer and end user has its own industry process accumulation and algorithm accumulation. These process algorithms are strictly confidential. Equipment manufacturers and end us...

Problems solved by technology

For example, the control system that supports the Profinet bus in the market is mainly the control system of Siemens, and the control system of Siemens is completely closed, and does not support customers to package their own algorithms, so it is impossible to realize the customer's independent algorithm expansion function

In addition, the Profinet bus configuration of the Siemens control system is fixed, and customers cannot tailor it independently

In addition, the communication function and real-time performance of the Siemens control system are limited

For the control of servo drives and frequency converters, Siemens' control system mainly supports the controllers independently developed by the company, and it is difficult to integrate other third-party servo drives and controllers, and the related control algorithms are relatively closed, and it is difficult to realize related Functions such as encoder configuration and pulse counting
