Abstract

A system arrangement and method are provided for allowing the operation of units in a fail safe manner and at low latency. The teachings suggest a specific protocol which allows switching and routing of packages for addressing and controlling light emitting diodes and reading out sensors. The information is distributed according to very specific requirements of the underlying topology and application domain. As light emitting diodes and sensors may affect the reliability of security features in a vehicle specialized approaches have to be provided considering both real-time requirements and reliability. In such a method, a branch device can change its operation mode without an explicit command but, in general, a command may provide an expiry condition of a mode after which the mode returns to its previous mode. Such an expiry condition may be the reception of a predefined number of specific network events.
