8.11 External data sources
External (remote) data sources might be used in visualizations. For this purpose a Data
Server must be available for the local application, handling the respective data sources.
8.12 Visualization Libraries
Due to the fact that visualization elements in »PLC Designer« V3.x are implemented as
function blocks, they are provided via libraries.
When adding a visualization object in a project, a certain set of visualization libraries
will be added to the Library Manager in the POUs view. The names as well as the
versions of these libraries are defined by the currently used visualization profile. The
profile also defines in particular which elements coming from the libraries will be
available in the visualization editor ToolBox.
A visualization library always is set up as a special type of "placeholder library", which
effects that the exact version of the library to be used is not resolved until the library
gets included in the project. Only then the currently active profile will define which
version actually is needed. Notice that this type of libraries is different from the device-
specific "placeholder libraries", where the placeholders get resolved by the device
description.
See in the following the basic libraries which are included by default when adding a
visualization object in a standard project. These libraries include further libraries,
which are not listed here. Usually you do not have to include the visualization libraries
manually or to use them explicitly in your applications:
• VisuElems.library (basic set of visualization elements)
• VisuElemMeter (meter and bar display elements)
• VisuElemWinControls (table, textfield, scrollbar elements)
• VisuElemTrace (trace element)
• VisuInputs.library (handling of inputs on a visualization)
