CANopen is a communication protocol stack and device configuration profile specification used in embedded systems for automation. In terms of the OSI model, CANopen implements the above layers, including the network layer. The CANopen standard consists of an addressing scheme, several small communication protocols, and an application layer defined by device configuration profiles. The communication … Read more
OD (Object Dictionary): This is an ordered, predefined group of objects that can be accessed via the network, with each object addressed by a 16-bit index and an 8-bit sub-index. The range of a node’s object dictionary is from 0X1000 to 0X9FFF. COB-ID (Communication Object Identifier): This is the message frame ID of the CANopen … Read more
In the field of industrial automation, communication protocols are like the nervous system of modern factories, and CANopen is undoubtedly the most reliable and efficient communication solution within this network. It is not just a communication standard; it is a vital link that connects devices and enhances production efficiency. This article will delve into this … Read more
CANopen is a high-level protocol based on CAN, which is widely used in various automation control systems. CANopen networks use twisted pair cables to transmit differential signals, but factors such as poor electromagnetic environment, non-standard wiring, and unreliable grounding in domestic industrial sites can directly affect communication quality and interfere with bus operation. To ensure … Read more
