Additional Information
In CIP routing, a node (Unit) that routes information subtracts the equivalent of one hop from
the timeout, deletes its own address from the route information, and relays the information to
the next node (Unit).
When a timeout is specified, the timeout for the actual request service processing is set in the
last hop.
In the case of relay hops, the timeout for the relay route must be added to the timeout for the
request.
OMRON products that support CIP subtract 5 seconds per hop.

IP Routing
The IP routing function sends IP packets to other network segments based on the routing information
set in the IP router table.
T
o communicate with devices on other network segments, you must set the IP router table and default
gateway settings for the CPU Unit and each device on the network appropriately for your network con-
figuration.
Precautions for Correct Use
You cannot create tag data links between multiple CPU Units using IP routing.
