1. A method for networking a first time-sensitive field bus with a second time-sensitive field bus, the first time-sensitive field bus comprising a first subscriber device and a first dedicated time domain, and the second time-sensitive field bus comprising a second subscriber device and a second dedicated time domain, the first and the second field buses being connected to each other via a gateway for data transmission, the method comprising:
defining the first time domain in the first field bus via the first subscriber device of the first field bus;
defining the second domain in the second field bus via the second subscriber device of the second field bus;
transmitting time-sensitive data in defined first time slots within a cycle duration of the first field bus;
transmitting time-sensitive data in defined second time slots within the second field bus; and
synchronizing the gateway as a slave with respect to the first time domain of the first field bus and additionally with respect to the second time domain of the second field bus, the gateway supporting at least two time domains simultaneously.
