Routing Tables
Section 8-4
The following example shows routing tables for sending data from PLC #1 (the
local node: network address 1, node address 1) to PLC #4 (the destination
node: network address 3, node address 2).
local node: network address 1, node address 1) to PLC #4 (the destination
node: network address 3, node address 2).
Note
In the above example, the routing tables required for a message to reach PLC
#4 from PLC #1 are shown. Additional settings would be required in the rout-
ing tables for a message to reach PLC #1 from PLC #4. Refer to 8-4-3 Rout-
ing Table Setting Examples for routing table setting examples.

Connecting and Using a Peripheral Device for the PLC
Routing tables must be created by a CX-Integrator connected to the PLC.
(They cannot be created using a Programming Console.) For details on how
to connect and use the CX-Integrator, refer to the CX-Integrator Operation
Manual (W445). (CX-Integrator is automatically installed when CX-One is
installed.)

to connect and use the CX-Integrator, refer to the CX-Integrator Operation
Manual (W445). (CX-Integrator is automatically installed when CX-One is
installed.)
Note
1.
When routing tables are transferred from the CX-Integrator to the PLC, all
of the CPU Bus Unit are reset so that the routing tables that have been cre-
ated can be read and enabled. Before transferring the routing tables, con-
firm that there will be no problems in the system when the CPU Bus Units
are reset.
of the CPU Bus Unit are reset so that the routing tables that have been cre-
ated can be read and enabled. Before transferring the routing tables, con-
firm that there will be no problems in the system when the CPU Bus Units
are reset.
2.
To transfer routing tables for multiple nodes to a PLC in one batch, connect
the CX-Integrator to a PLC with only one Communications Unit mounted.
Routing tables cannot be transferred to other nodes from a PLC with mul-
tiple Communications Units mounted.

3.
Routing tables can only be transferred as a batch to multiple nodes within
the same network as the PLC to which the CX-Integrator is connected.
the same network as the PLC to which the CX-Integrator is connected.
