1-4-2 IP Routing
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.
Version Information
For NJ-series CPU Unit, you can use the EtherNet/IP Unit with the CPU unit version 1.01 or later
and the Sysmac Studio version 1.02 or higher.
The two built-in EtherNet/IP ports on the NX701 CPU Unit both have the IP routing function. The IP
routing function sends IP packets to other network segments based on the routing information set in
the IP router table.
To communicate with devices on other network segments, you must set the IP router table and
default gateway settings for the NX701 CPU Unit and each device on the network appropriately for
your network configuration.
Precautions for Correct UsePrecautions for Correct Use
• You cannot create tag data links between multiple CPU Units using IP routing on the NX701
CPU Unit.
• The IP routing function can only be used with the NX701 CPU Units. IP routing cannot be used
with a combination of a built-in EtherNet/IP port on an NJ-series CPU Unit and an EtherNet/IP
Unit.
