To organize the blocks for the Step7 discipline, begin by creating a unit. A unit structures the blocks along the same lines as folders in a file system.

Create the Step7 unit in the T_Mechatronic_ModularSystem library.

1. Select the T_Mechatronic_ModularSystem library.
2. Select New > Unit in the shortcut menu.
3. Enter Step7 in the Name field.
4. Save the unit ([Ctrl] + [S]).

The new STEP 7 unit is displayed parallel to the Mechatronic unit.
