Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] see figure 2 . According to an implementation method for a driver integrating multiple industrial buses according to an embodiment of the present invention, the communication model of the driver is divided into a physical layer, a protocol layer, an interface layer and a driver application layer. The various industrial buses include Powerlink bus, EtherCAT bus and CANOpen bus.

[0022] The physical layer is located at the bottom of the entire communication model. The physical layer includes the network hardware interface and the CAN hardware interface. The protocol layer is located between the physical layer and the interface layer. The protocol layer includes the Powerlink protocol stack, the EtherCAT protocol stack and the Cia301 protocol stack of CANOpen ; The interface layer includes function interfaces, object collections and o...

Abstract

The invention discloses an implementation method of integration of various industrial buses on a driver, wherein a communication model of the driver is divided into a physical layer, a protocol layer, an interface layer and a drive application layer. The physical layer comprises a network hardware interface and a CAN hardware interface; the protocol layer comprises a Powerlink protocol stack, an EtherCAT protocol stack and a Cia301 protocol stack of CANOpen; the interface layer comprises a function interface, an object set and an object dictionary; and the drive application layer is used for implementing functions of a Cia402 protocol. The implementation method can simultaneously integrate functions of a Powerlink bus, an EtherCAT bus and a CANOpen bus on the driver, has higher transmission rate and supports synchronization of multiple drivers.

Description

technical field [0001] The invention relates to motion control technology, in particular to a realization method for a driver integrating multiple industrial buses. Background technique [0002] Networking is one of the important directions of industrial development. Whether it is Industry 4.0 or industrial robots in the national development strategy, higher requirements are put forward for networked products, which promotes the development of traditional fieldbuses in the direction of industrial Ethernet, while Real-time Ethernet is the best real-time industrial network in industrial Ethernet. In the field of motion control, Powerlink and EtherCAT have a relatively high market share, while in the traditional bus protocol, CANOpen is widely used in the field of industrial motion control because of its openness and multi-field standardization. Therefore, the demand for drive products (such as servos and frequency converters) integrating Ethernet Powerlink (hereinafter referr...
