Creating Routing Tables Section 3-9
42
The following example shows a routing table for sending data from PLC #1
(the local node: network address 1, node number 1) to PLC #4 (the destina-
tion node: network address 3, node number 2).
Note In the above example, the routing tables required to send a message in one
direction from PLC #1 to PLC #4 are shown. Similar settings would need to be
added to the routing tables to enable sending a message the other direction,
i.e., from PLC #1 to PLC #4.
3-9-2 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 a CX-Integrator, refer to the
CX-Integrator User’s Manual .
Note 1. When routing tables are transferred from the CX-Integrator to a PLC, the
CPU Bus Unit will be reset so that the set routing tables can be read and
enabled. Make sure that the equipment will not be adversely affected when
the CPU Bus Unit is reset before transferring the routing tables.
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.

To go to network #3,
first go to node #3 at
network #1.
To go to network #3,
first go to node #2 at
network #2.
(To go to network #3
according to the local
network table, go
through the unit
number of the local
CPU Rack.)
(The network is the same,
so go to node #2 at network #3.)
