Create a simple variable. Proceed as described in chapter Creating a simple variable. As a structure variable is based on a structure data type, select one.

Select a driver, a driver object type and the array dimensions.

The following options are available:

Automatic addressing

In the process zenon calculates an automatic address allocation. This depends on the granularity of the driver object type resp. the IEC datatype on which the datatype is based on.

Each data type starts with new offset

Defined the position of the single array elements for the automatic addressing. Either the offsets are used completely (variables are addressed in a row) when deactivated, or each structure starts at a new offset when activated.

Activate all elements

On creating the new array variable all elements are automatically activated.

Activae elements manually

On creating the elements are not activated. They have to activated in the variable list individually. This can be done via the context menu of the variable list.
