CANopen User Manual - Example of Estun ProNet Servo Drive (Part 1)

CANopen is a high-level protocol based on the CAN (Controller Area Network) serial bus system and CAL (CAN Application Layer). CANopen assumes that connected devices have hardware with a CAN transceiver and a CAN controller that comply with the ISO 11898 standard. The CANopen communication protocol CiA DS-301 includes periodic and event-driven communication, which not … Read more

Basic Principles and Applications of CANopen (Part 1) – Overview of CAN and Its Higher Layer Protocols

by
Basic Principles and Applications of CANopen (Part 1) - Overview of CAN and Its Higher Layer Protocols

From the OSI network model perspective, fieldbus networks generally implement only the 1 layer (Physical Layer), the 2 layer (Data Link Layer), and the 7 layer (Application Layer). Because fieldbus typically includes only one network segment, it does not require the 3 layer (Transport Layer) and the 4 layer (Network Layer), nor does it need … Read more

Fundamentals and Applications of CANopen (Part 3) – Predefined Connection Set

Fundamentals and Applications of CANopen (Part 3) - Predefined Connection Set

1、CANopenPredefined Connection Set To reduce the configuration workload of simple networks, CANopen defines a mandatory default identifier (CAN-ID) allocation table. These identifiers are available in the pre-operational state and can be modified through dynamic allocation. CANopen devices must provide the corresponding identifiers for the communication objects they support. The defaultID allocation table is based on … Read more

CANopen Device Designer: Accelerating CANopen Device Development

In the development process of CAN/CANopen products, configuring the object dictionary is a crucial step. Users need to have a sufficient understanding of the CANopen protocol, knowing the potential variables and transmission types in the device. It is also necessary to ensure that the design process does not violate the relevant definitions of the CANopen … Read more

Building Industrial IoT with CANopen Protocol

CANopen IoT is suitable for networks that do not support embedded internet protocols, allowing access to local and remote CANopen networks through network protocols and communication services. In many applications, specially designed mobile or tablet applications allow users to remotely control and maintain air conditioning and heating systems from anywhere. These applications also enable status … Read more

An Overview of CANopen SDO

by
An Overview of CANopen SDO

SDO is primarily used for reading and writing parameters of slave devices by the CANopen master. The most significant feature of SDO is the service confirmation, which produces a response for each message, ensuring the accuracy of data transmission. SDO communication is based on the client-server model, with the CANopen master node typically acting as … Read more
