CIP Message Communications
User-specified CIP commands can be sent to devices on the EtherNet/IP network. CIP commands,
such as those for reading and writing data, can be sent and their responses received by executing the
CIP communications instructions from the user program in the NY-series Controller.
Built-in EtherNet/IP port
By specifying a route path, you can send CIP messages (CIP commands and responses) to a device
on another CIP-based network segment via a built-in EtherNet/IP port or the EtherNet/IP Unit (CIP rout-
ing function for message communications). The maximum number of levels of CIP routing via the ports
is eight for any combination of CS, CJ, NJ, NX, and NY-series Controller. Note that the number of levels
of IP routing using an L3 Ethernet switch is not counted in the number of levels of CIP routing via the
ports.
In addition, CIP messages can be routed between Windows installed in an NY-series Industrial PC and
devices on an EtherNet/IP network via the internal ports and the built-in EtherNet/IP port on the Con-
troller.

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.
