In the development process of CAN/CANopen products, data analysis is a very crucial part. Data frame analysis software acts like a universal tool in your work. It should not only capture CAN data packets but also assist you in analyzing data functions, even arranging data in a rule-based sequence, allowing you to eliminate each issue … Read more
1、CANopen in the ISO Layer Structure From the perspective of the OSI 7-layer network model, the CAN (Controller Area Network) fieldbus only defines the 1st layer (Physical Layer, see ISO11898-2 standard) and the 2nd layer (Data Link Layer, see ISO11898-1 standard); in actual design, these two layers are entirely implemented by hardware, and designers do … 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
