Dear forum,

Maybe you can help a programmer coming from a Mitsubishi background..
I'm currently working with a MTP1000 HMI and sometimes when I do a small change to the HMI I get a question if I want to perform a Delta Download (see attachment).
When I perform this download, I see nothing changing to the HMI, what am I doing wrong? Can somebody point me to a manual, forum topic or something?

Everytime I do a modification I am forced to do a full rebuild and full download, this take quite a long time for this HMI. Any help is welcome!

Hi Jordski91,

To my knowledge delta download is available when small changes were done in the project and it download to the HMI panel will not lead to a runtime stop.

Here you can find more information about downloading projects to HMIs.

I hope you find this information useful.

Hi Jordski91,

unlike a full download, a delta download does not restart the runtime. The current screen is not reloaded either. But without a reload, you won't see any changes. So you need to make some screen changes to see the changes, or you need to restart the runtime.

Kind regards
Stefan
