2. The network address is the address of the network connected to the Unit
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).
1. The above example shows the routing tables for sending a message from
2. Refer to 7-4 Setting Routing Tables for an example of 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.
1. Routing tables cannot be set through Programming Consoles.
2. Networks cannot be crossed by a Programming Device without setting

ed to the Programming Device and other nodes in the same network. Dis-
connect and reconnect the Programming Device to each network when
