Large system
Typical for a large system are the following features:
Sensor data management is handled primarily by 2 sensor server PCs. These provide sensor data via
a redundant LAN to the radar servers.
The Radar server and primary radar HMI software run on different PCs. Data is exchanged via a
redundant network (100Mbit LAN). These PCs can also run other client applications.
Each radar HMI can display data from each radar server.
In order to cope with complete failure of the network (fall-back scenario), the radar servers are
equipped with a direct interface and run radar HMI software. This allows the radar servers to
function as stand-alone radars in the fall-back scenario when a display and track ball normally
connected to a multifunction station are connected to the radar server.
Stand-alone functioning of the radar system is realized by fall-back sensor data connections and a
direct connection to the display and track ball. In this case the radar system works without network.
Stand-alone is not a normal operational mode and is only to be used as fall-back in case of
complete failure of the Ethernet network.
The minimally necessary navigational data is always provided directly to the radar server (see fall-
back data lines in the figure). Note that in stand-alone mode the client software is run on the server
PC.
