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).
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.
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.)
