Variant modes of visualization
A visualization application, i.e. the visualization elements are created in IEC code in the
visualization editor of the programming system. In case the visualization is running on
the device, visualization code will be generated and loaded there. The four possible
visualization modes are described in the following. Which of them is used, depends on
whether at all and which type(s) of client object are inserted below the Visualization
Manager.
Target-Visualization combining PLC and visualization on one device.
»PLC Designer« HMI to run the visualization on an external device.
Web-Visualization using a web server to connect to the related application.
Diagnosis Visualization: visualization running in the programming system,
corresponding to a pure online visualization in »PLC Designer« V2.x.
All visualizations share the following characteristics:
• Within a visualization arbitrary expressions, even function calls, are valid.
• In contrast to »PLC Designer« V2.3 all visualization elements, so also the
visualization objects themselves, are implemented as IEC61131-3 function blocks.
So visualizations can be instanced and thus be referenced in other visualizations
and be used to extend other function blocks. A placeholder concept is realized by
handling placeholders as input variables of a visualization. They can be edited in an
interface editor. The use of Frame elements makes possible to reach easy toggling
between several visualizations within one visualization object.
• A visualization can be created as an object in the global object pool, that is the
POUs window, or in the Devices window, directly assigned to an application.
• Visualizations below an application are managed by a Visualization Manager,
handling common settings for all application-specific visualizations.
• Some general settings for all visualizations of a project (file paths, size fit etc.) can
be done in the Visualization options.
