Implementing access to an image
At locations in the application where an image should to be accessed, the image ID can be briefly specified. This is especially the case with visualizations. There you can configure elements which can display images with the image ID (qualified with <name of image pool>.<image ID>).
Image visualization element: Static ID property
Button visualization element: Static ID property
Image Switcher visualization element: Image on, Image off, and Image clicked properties
Cartesian XY Chart visualization element: Configuration of the background in the Dialog: XY Chart Configuration dialog
If an element should dynamically display multiple images one after the other, then a string variable is specified for it, not the image ID itself. The variable is set programmatically (in IEC code) to change the image IDs. In this way, a dynamic image display in the visualization element is achieved.
