6-3	Using FINS Message Communications
			There are two instructions that can be executed to send and receive data from
			CS/CJ-series CPU Units: SEND(090) and RECV(098). There is another
			instruction that can be executed to send any FINS command: CMND(490).
6-3-1	Setting Node Addresses
			Set the nodes for FINS message communications to node addresses other
			than 0. Node address 0 has a special meaning (local node) in message com-
			munications. If 0 is set as a node address for the Unit, message communica-
			tions will not be possible.
6-3-2	Creating Routing Tables
			The DeviceNet Unit functions as a Communications Unit in the same way as the
			SYSMAC LINK Unit, Controller Link Unit, and Ethernet Unit.
			It is therefore necessary to create routing tables for the communications func-
			tions to be used, as shown in the table below.

			viceNet Unit must be registered in that table.
			2. The DeviceNet Unit must be registered in the local network table.
