Tag logging reset at program update

[PetjaY]

I have data loggers that contain tags that i want to log, and a tag logging screen for showing them.
My problem is: how to make changes to the IX program without resetting the logs?

Generally HMI databases are not overwritten unless you modify the database that holds the data. Making changes to Alarms, Datalaogger, or Recipes could result in your data being overwritten. You can use the "Upload Database" button on the Project menu to pull the database off your panel. Then build your project. Next copy the database you uploaded from the panel to the "MyProjectName/Temp/Output" folder. That will overwrite the blank iX project database with the database you uploaded from the panel.

Now when you download your project to the HMI, it will download the database that you copied off the panel. You will need to do that every time you build your iX Dev project. Also, you can get into trouble if you are altering one of the previously mentioned objects because your database and your project may not match anymore.
