To automatically create the object tree, do the following::

1. Go to the Gate parking ACS object's setup panel.
   
2. Enter the controller's address range:  in the from field, enter the first address in the range (1); in the to field, enter the last address (2).
3. Click Device search (3).

This launches an automatic search for hardware-configured and connected Gate controllers. Objects corresponding to found controllers are automatically created in the object tree under the relevant Gate ACS object.

The Gate ACS's object tree is now created.
