Abstract
A method for operating a network arrangement having a plurality of network systems is disclosed. Data belonging to a first class is synchronously transmitted in a specified time slot identical for all network systems. A network system, which owing to a synchronization error during the specified time slot, receives data belonging to other classes from a plurality of senders, then only sends data belonging to the first class, but now in standard messages belonging to class 2. Non-vital data belonging to the other classes is no longer transmitted in this operating state. Improved failure safety and in particular a fail-operational mode is provided by the behavior of the network systems in the event of synchronization errors. A network system which implements the method and a network arrangement having a plurality of corresponding network systems is also proposed.
