We need to add new tags to some recipes inside a Wincc Hmi. Can we download the modified recipes to the Hmi, without losing the operation data values which are already on it? How? 

Hello Ziemens,

The way I do it is the following:

1. Create a button to export recipe data to a USB or SD card.

2. You load the project but without checking the option to overwrite the RT values.

3. In the RT you save the .csv from the created button.

4. You upload that .csv to the engineering project and you would already have the RT recipes in engineering.

Therefore, you can now make modifications having all the data.

Where is this menu, in the engineering software, which uploads the csv file to the project, so to have the actual operation data inside the recipe program ?  

On the other hand, do we have an option to download a recipe, with added elements, without overwriting the operation data running on the machine ?

I guess there is no menu. Just open the csv file (which has the same order of tags as the engineering project), copy the values, go to engineering software and paste the values there.

In my opinion: No.
