Abstract: A method of collecting event data in a wind park installation including a plurality of wind turbines is provided. Each wind turbine includes a satellite-based clock. In each wind turbine, a first time signal is distributed from the satellite-based clock to at least one node in the wind turbine. In the at least one node, events happening in at least one subsystem connected to the node are detected. When an event is detected, event data including an information about the event is collected. For each piece of collected event data, a timestamp is added to the piece of collected event data characterizing a corresponding instant of time when the event was detected. The timestamped event data is stored for later inspection.

Abstract: A control system for a wind turbine is provided. The control system includes a local terminal for locally generating wind turbine control commands, a control arrangement for generating control signals for the wind turbine on the basis of wind turbine control commands, and a switching arrangement for switching between a remote mode of operation over a main communication network, and a local mode of operation over a local communication network between the local terminal and the control arrangement such that a message passed between the local terminal and the control arrangement does not travel beyond the local communication network in the wind turbine. A method of locally controlling a wind turbine, and a wind park including a number of wind turbines, wherein each wind turbine comprises such a control system are also provided.

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.
