POWERLINK has been integrated with the well-known and widely deployed CANopen family of communication and device profiles. CANopen's DS301 and DS302 communication profiles have been adapted to POWERLINK in a joint technical working group of both the EPSG and the CiA (CAN in Automation) group. Users and vendors of CANopen-enabled devices are now able to easily migrate their applications from the well-established CAN bus to an Ethernet environment which is a hundred times faster. CAN bus and Ethernet networks can be transparently combined wherever needed.
