Overview
The schematic status display (Schematic Status Display (SSD, formerly named Scada display) in Delft-FEWS is used for displaying and monitoring data. The schematic status 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 schematic status display configuration file. The schematic status 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 schematic status display SSD is comparable to the main map display, only the schematic status display SSD does not and cannot refer to any geographical coordinate system. Furthermore the schematic status display SSD can be used to show text and figures as well as objects that represent data values.

Please note that the schematic status display SSD 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 schematic status display shows one or more status panels, which can be selected in turn from the list on the left hand side. It is also possible to have multiple schematic status displays, each one with different panels. In that case there would be one configuration file for each different schematic status display, each one with a different filename. The filename of each schematic status display should be registered in the DisplayInstanceDescriptors.xml configuration file. When available on the file system, the name of the xml file for configuring a schematic status display is for example "StatusTwentekanalen.xml". To register a schematic status statu display in the DisplayInstanceDescriptors configuration file use e.g. the following xml code:

If specified, then the tags in the text of this component are replaced using data from the specified variable. Tags should be separated by "%" signs. Text can be e.g. "Last value = %LASTVALUE(numberFormatId)%", which would be replaced by e.g. "Last value = 10.0". The following tags can be used in the text (numberFormatId/dateFormatId should be replaced by the id of a numberFormat/dateFormat that is defined at the start of this configuration file):
