To navigate different SSD displays and panels within a SSD display, (starting with FEWS release 2019.02) specific elements can be added to the topology.xml configuration, as in the following example.

...

This element will bring the open SSD display (if any) to ) the front, this element is optional and works well if only a single SSD display is open. In case you need to be able to open multiple SSD displays at the same time you may want to omit this element, in that casewhich the <ScadaDisplayId> element will control which window is brought to front.

scadaDisplayId

This element will first check if the SSD display with the given ID is already open, if so, this display will be brought to font to give it the focus. If the SSD display is not already open, explorer will try to re-use another SSD display and load the SSD display with given ID to replace the current content. If no SSD display is open, nothing happens, at least one SSD display must be opened as an explorer task for it to be able to respond to selection changes in the Topology panel.

scadaPanelId

This element can be combined with the scadaDisplayId element to navigate to a specific SSD panel in the given display. Explorer wil first look for an open display which contains the relevant SSD display and selected the SSD panel in this display as if the user selected this from the list of avaiable SSD panels in this display.

Known Issues

When using Delft-FEWS the configuration can be present as files on the file system or can be contained in a local data store. The svg files that are used for the schematic status display work in both cases. However, if the svg files refer to separate image files, then the schematic status display can only display these images if the image files are present as files on the file system. If these separate image files are contained in a local data store, then they cannot be displayed in the schematic status display. Therefore, when using separate image files, make sure that the configuration is present as files on the file system. If this is not possible, then it is possible to choose from two different workarounds:
