Based on the Industrial Internet of Things and Industry 4.0 verification, CANopen
CANopen FD is very suitable for the integration of embedded networks into industrial IoT applications. The high communication flexibility is due to the powerful USDO service. USDO conveniently enables communication between any running CANopen FD devices. Moreover, the high data throughput provided by CANopen FD supports extensive status monitoring and big data applications. To achieve the integration of the CANopen FD network into the Industry 4.0 environment, CiA is developing the specification document for mapping CANopen FD services and specifications to OPCUA.
Real-time, reliability, and robustness
CANopen FD is a technology based on proven CAN and CANopen. CAN and CAN FD were originally developed for automotive applications, thus they can meet very strict requirements for reliability, robustness, and power consumption. As the name suggests, CANopen FD also integrates the advantages of CANopen technology. Not only that, CANopen FD was also designed with simplicity in mind. The event-driven operation mode of CAN FD, higher bit rates, and improved protocol efficiency significantly shorten system response times.
Can be used to implement more advanced safety features
Embedded networks are facing increasing demands for functional safety and security. One typical aspect is verifying the correctness of network participants. In some other applications, even data encryption or data frame encryption is necessary. Thanks to the extended payload of CAN FD, the functional safety protocol of CANopen FD can be fully transmitted in a single frame. Additionally, this functional safety protocol information can also be encrypted as needed.
Existing second sources and device interoperability
Some companies have already implemented the CANopen FD specification in their devices. At CANopen FD plugfests, the first CANopen FD prototype demonstrated interoperability of CANopen FD in real systems consisting of devices from different manufacturers. Some semiconductor manufacturers have begun to offer CAN FD controllers and transceivers. Additionally, some vendors have also started providing interface boards and related tools. Through the necessary CANopen FD evaluations, CiA has verified the consistency of CANopen FD devices. The CANopen FD specification document also ensures the interoperability of devices.
Low-cost hardware, software, and related tools
Currently, CANopen FD software, hardware units, and tools can be purchased at reasonable prices from various suppliers. CANopen FD and CANopen FD devices can be expanded or simplified as needed. This feature can provide a lot of convenience for CANopen FD users. Users can choose the most suitable products based on the required functions and prices. The operating principles of CANopen and CANopen FD are basically the same. Understanding CANopen and the CANopen tools and network topology simplifies the upgrade from an existing CANopen solution to a CANopen FD solution.

In 1992, several companies jointly established the CiA International Users and Manufacturers Alliance, which provides a neutral platform for the development of the CAN bus protocol and the promotion of this technology. We regularly send out information on CiA activities and the latest developments in CAN and CANopen bus technology.
