Create tags

This part of the tutorial shows how to create new tags by adding them to the Project Tags datasheet.

A tag is any variable that holds a value. All tags created in a project are stored in the Project Tags folder, on the Global tab of the Project Explorer.

1. In the Project Explorer, click the Global tab.

2. Double-click Project Tags to expand the folder.

3. Double-click Datasheet View to open the Project Tags datasheet.

4. Use the following parameters to create a tag for the sample project.

   1. Name: Specify a unique tag name. For this tutorial, type Level.

   2. Array Size: Specify the top array index of the tag. (Simple tags have an Array Size of 0.) For this tutorial, type 3.

      Each array index corresponds to one of the three tanks:

      • Level[1] is the level of Tank #1

      • Level[2] is the level of Tank #2

      • Level[3] is the level of Tank #3

      You will not use Level[0] in this tutorial, even though it is a valid tag. It is easier to understand if the array indices match the tank numbers.

   3. Type: Specify the data type of the tag: Boolean, Integer, Real, String, or Class. For this tutorial, select Integer.

   4. Description (optional): Type a description of the tag for documentation purposes only.

   5. Scope: Specify how the tag is managed between the Server and the Thin Client stations.

      • Select Local if you want the tag to have independent values on the Server and Client stations.

      • Select Server if you want the tag to share the same value on the Server and Client stations.

      For this tutorial, select Server.

      

5. Save and close the Project Tags datasheet.

You will create additional tags as you build the project.

Tip: You can sort the data in the Project Tags datasheet or insert/remove additional columns by right-clicking on it and then choosing the applicable option from the pop-up menu.
