Abstract: A method for operating a real-time-capable simulation network having multiple network nodes for computing a simulation model. The network nodes are connected to one another via a serial data bus, and the network nodes exchange data via data bus messages. At least one event-driven task of the simulation model is implemented on a first network node, and a nondeterministic triggering event is detected by a second network node. The second network node communicates the detected triggering event to the first network node and the first network node computes the event-driven task. A fast response time is achieved by the means that a detection signal is sent from the second network node in the form of a multicast data bus message or a broadcast data bus message to multiple network nodes of the simulation network or to all network nodes of the simulation network over the serial data bus.
