Claim 0:
1. A method for actuating execution units in an automotive LED network, comprising:
providing (100) a physical automotive LED network of a plurality of series sub-chains of execution units, the individual sub-chains being addressed in series 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 upstream communication node, 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 switched 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 output interface and the at least one input interface and the at least one output interface are explicitly lockable;
sequentially checking (101) each of the sub-chains of the plurality by means of a query to the corresponding upstream communication node, which upstream communications node assigns (102) 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
actuating (103) at least one execution unit, by means of the upstream communication node, with a command generated by a control unit upstream from the communication chain.
