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. Furthermore the scada display can be used to show text and figures as well as objects that represent data values.

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. |

textComponentBehaviourDefinition
One or more items to define special behaviour and/or properties for components in this scada panel. Each item refers to an svg object that is defined in the given svg file. Each item also contains definitions of behaviour and/or properties for that object. This way it is possible to e.g. replace tags in the text of a text object with certain values from a certain time series, or to define what should happen when the user clicks on a certain component.
Definition of special behaviour and/or properties for a text component in this scada panel. This refers to an svg object of type "text" that is defined in the given svg file. This contains definitions of behaviour and/or properties for that svg object. An svg object of type "text" can be a "text", "tspan", "tref", "textPath" or "altGlyph" element.
