CAN bus has had much success, particularly in machine manufacturing, and is steadily gaining importance. High resistance to disturbance, high-speed data transfer, ease of use and deterministic real-time behavior are among the reasons for this success. CAN is the ideal fieldbus for applications with a manageable number of remote I/O nodes and few axes. As a fieldbus, CAN bus reaches its limits when dealing with larger and more complex machines. For these applications, however, POWERLINK is the ideal expansion into the higher performance range.
