One or a plurality of sub-networks (SN1, SN2, SN3, SN4) are defined in the communications network, which each comprise a plurality of network nodes (N1, N2, N14) from the communications network, wherein one or a plurality of the sub-networks represent pre-determined sub-networks (SN1, SN2, SN3), in which respective pre-determined network nodes (N1, N3, N5) have both the function of a global slave node (GS) and the function of a local master node (LM), and the one or the other network nodes (N2, N4, N6, N8) of the respective pre-determined sub-networks (SN1, SN2, SN3) are local slave nodes (LS). The method is characterised in that, in addition to global synchronisation using the global master node (GM) and the global slave nodes (GS), local synchronisation is also performed in the pre-determined sub-networks (SN1, SN2, SN3) using the local master node (LM) and the local slave nodes (LS). It is thus achieved that, in the event of an error outside a pre-determined sub-network (SN1, SN2, SN3), the local synchronisation can be continued, whereas the global synchronisation is aborted. It is thus avoided that an erroneous synchronisation is propagated into corresponding sub-networks. |
