Omron NX102-12 Series User Manual

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 NJ/NX-series CPU
Unit.

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
routing function for message communications).
The maximum number of levels of CIP routing via the ports is eight for any combination of CS, CJ, NJ,
and NX-series CPU Units. 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.

NX701 CPU Unit and NX102 CPU Unit
Because there are two built-in EtherNet/IP ports, CIP routing is possible by the CPU Unit alone.
