Embodiment Construction
[0052] Fig. 1 is a schematic diagram of a system including a VLAN (Virtual Local Access Network). The system is used to control energy production plants such as wind turbine plants. VLAN contains an external network 1,2 and an internal network 3,4. The external networks 1 and 2 include a data network 1 and a service network 2 . Likewise, the internal network includes a data network 3 and a service network 4 .
[0053] The external data network 1 and the internal data network 2 communicate via the control unit 5 . However, the communication between the external data network 1 and the internal data network 3 is controlled by the switch 6 . Likewise, the communication between the external service network 2 and the internal service network 4 is also controlled by the switch 6 .
[0054] Coupled in parallel to the switch 6 and between the internal data network 3 and the internal service network 4 is a first data filtering means 7, such as a router and / or a firewall. The first ...

Abstract
The invention relates to a system for operating a plant. The plant comprises data equipment. The data equipment is provided at the location of the plant itself. The 5 data equipment comprising a data structure divided into at least a first data storage device (1,2,21,22) and a second data storage device (1,2,3,4,23). The at least first data storage device (1,2,21,22) is accessible from an external data source. The status of the first data storage device (1,2,22), during operation of the system, is determined as being trusted or un-trusted. The status of the 0 second data storage device (3,4,23), ab initio, is determined as being trusted. The external data source is connected to the first data storage device (1,2,22) and to the second data storage device (1,2,3,4,23), and the second data storage device (1,2,3,4,23) is connected to the first data storage device (1,2,22) along a data interfacing device (6,25,26).
Description
technical field [0001] The present invention relates to a factory operating system, especially suitable for energy production units such as wind farms, and other factories that need to be monitored and controlled can also be operated by the system according to the present invention. The invention also relates to a method of operating a plant using the system of the invention. Background technique [0002] The plant is monitored and operated, either locally at the plant or operated from a central monitoring site. The communication between the operated factory and the central site is realized through a dedicated communication network to ensure safe, reliable and uninterrupted communication between the factory and the central site. This communication is carried out by using a strict non-public communication network. [0003] US 2003 / 0208448 discloses a semiconductor wafer data brokering system (a data brokering system for semiconductor wafer data), comprising: a manufacturer (...
