| 1. A method to test a network made up of network nodes and devices connected to the network nodes, the method comprising:
determining a current network topology using a number of the network nodes, each network node including a node memory to store
first data, the first data indicating at least a network-node identity and an interconnection configuration of network-node
outputs, using a network-node identity, and using an interconnection configuration of network-node inputs and network-node
outputs, by reading in data for the current network topology from a central network-topology memory for the network, and from
at least one decentralized network-node memory storing at least a network-node identity and an interconnection configuration
of network-node outputs;
comparing the current network topology to a stored, reference network topology for the network, to detect a change in at least
one of a number of devices connected to the network, types of the devices connected to the network, a network topology, the
number of network nodes, and types of the network nodes;
restoring the reference network topology by automatically deactivating at least one of at least one network node, at least
one network-node output, and at least one device at the network nodes, which are not provided in the reference network topology;
and
storing, only on demand, the current network topology as the reference network topology if it is determined that the current
network topology is permissible.
