Claim 9:
10. A system arrangement for actuating execution units in an automotive LED network, comprising:
a physical automotive LED network of a plurality of series sub-chains of execution units, the individual sub-chains being addressable in series and being set up such that upon failure of an execution unit of a particular sub-chain of the plurality, the rest of the sub-chain fails, each sub-chain initially having exactly one communication node connected upstream, wherein the communication nodes of each of the plurality of individual sub-chains are chained together in series such that there is a communication chain of upstream communication nodes, with individual communication nodes being switchable to be passive upon failure of the corresponding sub-chain of the plurality in such a way that the rest of the communication chain persists, wherein the communication nodes each have at least one input interface and at least one out-put interface and the at least one input interface and the at least one output interface are explicitly lockable;
the communication nodes being configured for sequentially checking each of the sub-chains of the plurality by means of a query to a respective upstream communication node of the corresponding sub-chain, which upstream communication node is configured to assign a unique identifier to each execution unit of the corresponding sub-chain such that each execution unit in the network is assigned a unique identifier; and
a control unit set up for actuating at least one execution unit, by way of the upstream communication node, with a command generated by a control unit upstream from the communication chain.
