On occasion of its 30^th birthday, the CAN Newsletter magazine included in all four issues of 2022 feature articles, which focused on dedicated application fields called “history and trends”. The March issue began with the article ‘From eight to more than 700 members’ in which Holger Zeltwanger, the CiA initiator, reflects some of the important milestones of CiA. In ‘CAN in elevators’ it is all about CANopen Lift and how in 2002, CiA members started to develop the CiA 417 profile for lift control systems. The goal was to agree to a common specification, which enables suppliers to design interoperable CAN-connectable devices for elevators. ‘CAN lower OSI layers’ is about the development and implementation of the first CAN generation, which started more than 30 years ago. Today, CiA already has released the third CAN generation known as CAN XL. ISO standardization was always an important issue: The next editions of ISO 11898-1 (data link layer and physical coding sub-layer) and ISO 11898-2 (high-speed media access unit sub-layers) covers Classical CAN, CAN FD, and CAN XL. ‘CAN in agriculture and farming’ focuses on how CAN helps to provide people with food and beverage.

The September issue was kind of special since we printed some issues for the exhibitions Innotrans and Bauma. So, it is obvious that the topics were ‘CAN on construction sites’ and ‘CAN on rails’. In cranes, pavers, earth-moving machinery, and other equipment used on construction sites, embedded CAN networks are used for many purposes. CANopen and J1939 are the most applied higher-layer protocols. The next step is the migration to CANopen FD and J1939-22 as well as to CAN XL in a long term. Additionally, CAN serves in many rail vehicles as embedded and deeply embedded network. In many cases, CANopen is used as higher-layer protocol.
