A network node ( 1 ) with a communication unit ( 2 ), which is provided for the implementation of a communication protocol for the purpose of communication with other network nodes via a communication medium ( 5 ), and with a bus monitor ( 3 ), which, mutually independently, each implement an access time schedule contained in a configuration data record, and which each make available, in accordance with the access time schedule, a release signal for a bus driver ( 4 ) provided in the network node ( 1 ), which evaluates these two signals and, in the event that the two release signals do not coincide, blocks the access of the network node ( 1 ) to the communication medium ( 5 ).
