Abstract

A network device which is connectable to a data communication network is provided. The network device includes at least two device components including a first device component. Each device component has a communication interface, which is accessible via an internal static network address, associated for communicating data. The network device further includes a node device having an internal interface for communication with the communication interface of each of the at least two device components and an external interface for communication with an external device different from the network device. The node device is configured for receiving external data from the data communication network and providing to the first device component, in response the external data and by using the internal network address of the first device component, component specific data related to the first device component.

6. A method of operating the apparatus according to claim 1 , the method comprising:
receiving with the node device included in the wind turbine, the external data from the external device via the data communication network;
the node device providing to the first device component, in response to the external data and via the internal communication network, the first component specific data related to the first device component;
the first device component in response to the provided first component specific data, associating the first global network address with the communication interface of the first device component;
receiving with the first device component, communications from the data communication network addressed to the first global network address;
the node device providing to the second device component, in response to the external data and via the internal communication network, the second component specific data related to the second device component;
the second device component in response to the provided second component specific data, associating the second global network address with the communication interface of the second device component; and
receiving with the second device component, communications from the data communication network addressed to the second global network address.

7. The method according to claim 6 , wherein the first component specific data are provided to the first device component by using a fixed internal network address of the first device component, the fixed internal network address identifying the first device component in the internal network.

8. The method according to claim 6 , comprising:
receiving with the external device at least one configuration request from the wind turbine, the configuration request including a device identifier identifying the wind turbine;
