2. CAN bus specifications
2.1 ISO layers and CAN bus
The standard ISO 11519 of the CAN bus specifies :
in part A, an 11-bit identification field ("standard" format);
in part B, a 29-bit identification field ("extended" format).
Note: in this article, only the standard format will be presented; the difference with the extended format will only concern the size of the identifier.
This standard defines the physical layer, or layer 1 in the ISO sense of the term, which is responsible for defining the signal on the media, the electrical interface and bit coding, and layer 2,...

Websites
The international association CiA (CAN in Automation) was founded in 1992 to promote the use and development of the CAN network by providing information and expertise on its techniques, products and marketing. Annual membership costs €550 ex VAT for educational establishments, and varies according to the size of the company (€700 for less than 10 employees, up to €9,900 for more than 100,000).
Events
Conventions, trade shows, symposia and study days are generally listed on the website of the non-profit association CAN in Automation (CiA). CiA is the international organization of users and manufacturers that develops and supports CAN-based upper-layer protocols. CiA organizes webinars and publishes a newsletter with various technical, commercial and regulatory information on the CAN bus.
