# Create recipe files

Recipe files define recipe units that pair sets of data values with sets of tags so that operators can write the values to the tags in one operation. When you create a recipe file, you define the ingredients that make up the recipe, whether they are number or string type, whether there will be maximum and minimum value limits, what the data values for each ingredient will be, and what tag each value will be written to. You create a recipe unit by associating a data set with a tag set.

Use the RecipePlus editor to create and edit recipe files. An HMI project can include multiple recipe files.

## To create a recipe file

1. Open the RecipePlus editor using one of these methods:
   - If the RecipePlus editor folder is empty, double-click the RecipePlus editor folder icon; this creates a new recipe file and opens the editor on that file.
   - Right-click the RecipePlus editor folder icon and select New from the Context menu; this creates a new recipe file and opens the editor on that file.
   - From the File menu, select New > RecipePlus; this creates a new recipe file and opens the editor on that file.
   - Right-click an existing recipe file in the folder and select Open from the Context menu.
   - Double-click an existing recipe file in the folder.
2. Define the recipe file in the General, Ingredients and Units tabs of the Properties dialog box.

   Tip: | Multiple instances of the RecipePlus editor can be open at one time; however, only one instance of any recipe file can be open at any one time. When the RecipePlus editor is open, the menu bar at the top of the FactoryTalk View Studio frame will include two additional menus: Edit and Recipe.
