	2. The network address is the address of the network connected to the Unit
	(between 1 and 127). The address is set when the local network table is
	created.
Relay Network Table	A relay network table provides the node and network addresses correspond-
	ing to the initial relay point (first point the data must go to) en route to a target
	network (end network) not directly connected to the local PLC.
	The table traces the route from the relay point to the end network.
	The example below shows the routing tables for the route from local node
	PLC1 (network address 1, node address 1) to PLC4 (network address 3, node
	address 2).

7-4 Setting Routing Tables

This section describes routing table settings.

Routing tables are set through the CX-Net (in CX-Programmer), SYSMAC LINK, or Controller Link Support Software. This section describes setting pro- cedures and setting details.

See the operating manual of the Programming Device you are using for the specific setting procedure.

Note 1. Routing tables cannot be set through Programming Consoles.

2.Networks cannot be crossed by a Programming Device without setting routing tables. Routing tables can therefore be set only for nodes connect- ed to the Programming Device and other nodes in the same network. Dis- connect and reconnect the Programming Device to each network when setting routing tables in multiple networks.

3.Make sure that the routing tables are properly set at all nodes on the net- work. If a message is sent to a node without correct routing tables, trans- mission will not work properly and a response may not be returned.
