CANopen Features
•
open fieldbus (specifications have been released),
•
maximum communication speed of 1Mbits/s,
•
noise resistance improved by the resend process of the hardware,
•
interoperability and interchangeability of devices,
•
supported by a large number of international manufacturers (approximately 500 member companies),
•
access to all device parameters,
•
supports cyclic communication and acyclic communication (event-driven), thereby reducing bus data
volume and increasing response speed.
