Integration of CAN-based Networks into the PROFInet Environment
Axel Pöschmann, Lutz Rauchhaupt, Thomas Werner, V. Magdeburg · 2003
PROFInet is an international standard for Ethernet-based industrial communication systems. It considers the integration of fieldbus systems, such as CANopen, which is well established in the field level of industrial automation. In the paper the different concepts of the PROFInet model are introduced. In particular the so called migration concept is explained, which deals with the possibility to integrate fieldbus systems into the PROFInet environment using a so called Proxy device. For CANopen the architecture of such a Proxy is described and the relation to the CANopen model elements is discussed. Finally an implementation concept of a CANopen Proxy with static CANopen device assignment is presented. Ethernet meets CAN Solutions which combine Ethernet-based communication (mostly also IP-based) and CAN-based communication have been known for a long time (e.g. [1], [2]). However, in factory automation, the open
