Abstract

The invention belongs to the technical field of the industrial embedded control, and discloses an industrial embedded control system based on a CANopen bus. The system comprises a power supply module,a parameter configuration module, a master control module, a program loading module, a redundancy control module, and a CANopen management module. the CAN open management module is used for a controlsystem of a CANopen network, the customization of the node amount in the CANopen network and the node communication data size are realized through the CANopen configuration management module, the CANopen bus management module and the CANopen node management, the node amount and the communication capacity of each node in the CANopen network can be flexibly configured; the flexibility of the CANopen network management is greatly improved under the limited COB-ID resource, and the data transmission capacity of single node is optimized.

Description

technical field [0001] The invention belongs to the technical field of industrial embedded control, in particular to an industrial embedded control system based on CANopen bus. Background technique [0002] CANopen is a high-level communication protocol based on the Controller Area Network (CAN), including communication sub-protocols and device sub-protocols. It is often used in embedded systems and is also a field bus commonly used in industrial control. CANopen implements the agreement above the network layer (including the network layer) in the OSI model. The CANopen standard includes an addressing scheme, several small communication sub-protocols, and an application layer defined by a device sub-protocol. CANopen supports network management, equipment monitoring and communication between nodes, including a simple transport layer, which can handle segmented transmission of data and its combination. Generally speaking, the data link layer and the physical layer will be i...
