CAN-technology was developed for embedded hard real time automotive applications. CAN-bus together with high-level application protocols is used now to control large experimental installations and particle accelerators. CAN-technology includes fieldbus, universal and specialized controllers, sensors and actuators. Software components of CAN-technology consist of high level application protocols, programs for testing, monitoring and configuring of CAN-nodes as well as the components which bind CAN-components with SCADA systems and ensure control through the WEB-browsers. CAN-technology is used in INP to control accelerators, for beam diagnostic and, in cooperation with the RRC Kurchatov Institute, in automation of the large neutrino detector Borexino. CAN-bus adapters for PC have been constructed. Such software components as drivers for PC adapters, the bus emulator and protocol analyzers have been developed under Linux. Original specialized high level protocols have been developed for closed specialized systems. Source codes have been developed and verified for compatibility with international standards such as DeviceNet and CANopen for use in the systems that are supposed to be extended with commercially available software and hardware components. Long-term positive experience of CAN-technology usage allows us to recommend this technology for accelerator control especially if industrial style and compatibility is desired.
