Assigning a structure as a data type

You can think of a user defined structure as a complex data type.
When you configure a structure in a Global Variables device, it becomes available from the New Variables window Type drop-down list.

When you configure a new variable, you can assign the structure as the data type.

To create a new variable, follow the steps in Configuring Global Variables device variables; however, the data type to select will be the new structure.
For this example StructureGVar is the variable of type StructureA.

When the new variable is configured, and the Global Variables device started, the variable becomes available from the Variables tab.

Notice that the StructureGVar variable is composed of four fields that comprise the StructureA data type (which was configured as a structure).
