General notes on the web service
The visual energy 4 web server features a WCF web service to grant access to data objects, mainly for reading purposes. This web service can be used for custom visualization and evaluation or to process the data on another system. This way, you can access energy data as well as live values, but also basic information such as projects, locations, distributions or meter points.
Web service configuration
Up to version 4.6 R5, only a SOAP URI is entered in the Web.config. If you, for example, want to enable access with an Ajax client, an additional entry is required:
<endpoint address="/json" binding="webHttpBinding" behaviorConfiguration="DataServiceAspNetAjaxBehavior" contract="Kbr.VisualEnergy4.UI.Web.DHTMLSuite.Services.IExcelDataService" ></endpoint>
As of release 6, this entry should already exist in new installations.
