METHOD FOR TESTING A NETWORK, AND CORRESPONDING NETWORK

A method for testing a network made up of network nodes and devices connected to network nodes, includes: determining the network topology, using at least the network topology, using at least the number of network nodes, the network-node identity, and the wiring of the network-node inputs and outputs; and comparing a current network topology to a permanently stored, reference network topology for the network, in order to detect a change in the number and/or type of devices connected to the network, in the number and/or type of network topology, and/or in the number and/or type of network nodes at which a change is present.
