Yes, you can replace the default startup screen on an HMI with one of your own choosing. The graphic file must be in a bitmap format (*.bmp).
For best results, size the graphic so that it is the same size as the HMI screen in pixels.
You can download your custom startup screen along with the project you are downloading to the HMI by selecting the “Use user-defined startup screen” option in the Download window.
See Tech Note 5056, “Startup Screen on HMI5000 Series” for more information.
