8.15 Web-Visualization
The Web-Visualization can be used, if there is an WebVisualization object inserted
below the Visualization Manager object. This is only possible if the target system
supports Web-Visualization. In this case a special Web Server must be available,
enabling the communication between target system and web client. Whether the
WebVisualization object is inserted automatically or must be added manually,
depends on the device description of the target.
The Web-Visualization is realized as a Java applet which during startup requests the
complete visualization paint information from the web server. After that only the
paint changes get transferred cyclically. At a download of a visualization project all
files required for the Web-Visualization are transferred to the subdirectory /visu of the
target system. This concerns the Java applet, the base HTML-page (*.htm-file) of the
visualization and all images needed in the visualization.
Preconditions for a Web-Visualization:
• Target system with appropriate configuration and web server
• Specification of the start visualization and the name of the htm-file to be
downloaded (in the Visualization Manager)
• Web browser: IExplorer or Mozilla Firefox; plus Java-VRM as from V1.4
Note: The VISU_TASK, which automatically gets added to the Task Configuration
with the adding TargetVisualization or WebVisualization below the Visualization
Manager, will be removed when the last of these client objects was deleted or set to
"Exclude from build" in its property settings.
Configuration in the programming system
The settings for a Web-Visualization concerning data transfer, display size, start
visualization and htm-file must be done in the Visualization Manager in sub-object
Web-Visualization.
Configuration of the target system
It might be that the Web-Visualization functionality still must be configured in the
target system. The following entries must be valid in the configuration file
<targetsystem>.cfg:
[ComponentManager]
Component.<n>=CmpWebServerHandlerV3
Component.<n>=CmpWebServer
[CmpWebServer]
