Preconditions
Since the TwinCAT 3 visualization is implemented based on the IEC61131-3 standard, certain libraries have to be integrated in the project, which provide the required functions and visualization elements. Visualization profiles are used to define the selection of the visualization libraries, and from these the selection of elements to be made available in the visualization editor object. When the first visualization page is added, the libraries specified by the profile are automatically added to the PLC project.
