Scada Display

The scada display in Delft-FEWS is used for displaying and monitoring data. The scada display shows one or more configurable schematic views that represent data values in some way. For example, to show the most recent data value of a given time series, it is possible to show just the numerical value, or to show a rectangle that varies in height depending on the data value, or to show a polygon that changes in colour when the data value crosses a certain threshold, etc. How data is represented and which data is shown can be configured in the scada display configuration file. The scada display is dynamically updated whenever new data becomes available in the system or whenever data is changed (e.g. in the time series editor). The scada display is comparable to the main map display, only the scada display does not and cannot refer to any geographical coordinate system.

Please note that the scada display in Delft-FEWS is only used for displaying data, it does not implement all features that could be expected from a SCADA (Supervisory Control And Data Acquisition) system.

The scada display shows one or more scada panels, which can be selected in turn from the list on the left hand side. It is also possible to have multiple scada displays, each one with different panels. In that case there would be one configuration file for each different scada display, each one with a different filename. The filename of each scada display should be registered in the DisplayInstanceDescriptors configuration file. When available on the file system, the name of the xml file for configuring a scada display is for example "ScadaTwentekanalen.xml". This scada display would be registered in the DisplayInstanceDescriptors configuration file with the following xml code:

<displayInstanceDescriptor id="ScadaTwentekanalen">
    <description>Scada Display Twentekanalen</description>
    <displayId>ScadaDisplay</displayId>
</displayInstanceDescriptor>
