2. Initial setting
This section describes the initial setting to enable the gateway function.
2.1 Node number setting
When connecting the gateway, set node numbers for the controllers to be connected. Set node number “1” for
the controller that becomes the top of the gateway, and then node numbers “2”, “3”, and “4” for subsequent
controllers in order.

Set node numbers using K38 (Node). There are two kinds of setting methods. One is that K38 is edited directly
and the other is “automatic node number setting” that automatically assigns node numbers to K38 in the
controller arrangement order.
For details about automatic node number setting, see the section, “Node number setting”, in the Daisy Chain
Guide.
