10.1.7 CanOpen operator F5 00.F5.060-5010 / 5011
CAN is a Multi-Master-System . This means every node has access to the BUS and can send telegrams. In
order to prevent problems when two nodes simultaneously access the BUS, the CAN-BUS has an arbitration
phase which determines who may continue to send his telegram. When there is a conflict in accessing BUS the
user with the lowest telegram number (identifier) has priority. This user then can completely send his telegram
without repeating the first part. All other nodes go into receiving status and stop sending their telegram. Thus it
is determined that lower telegram numbers have automatically priority. The available telegram numbers in the
CAN version 2.0A are limited to 2032 identifiers (0...2031).
