Additional Information
Unit Addresses
A unit address is used to discriminate several devices connected to a single node on a network.
Set the unit address as shown below.
• CPU Unit: 00 hex, 01 hex
• CPU Bus Units (EtherNet/IP Units): Unit number + 10 hex
 NX701 CPU Unit
The route path notation is different for communication using built-in EtherNet/IP port 1 (CPU#00)
and for communication using built-in EtherNet/IP port 2 (CPU#01). This section provides examples
of route paths.
This example explains communication via an NX-series CPU Unit.
(1) Using built-in EtherNet/IP port 1 (local CPU #00)
(Local CPU #00 to destination CPU #00)
Local CPU #00 to destination IP address
• Network type number: “02” (Output to communication port)
• Destination address: Specify the destination IP address
(2) Using built-in EtherNet/IP port 2 (local CPU #01)
(Local CPU #00 to destination CPU #01 via local CPU #01)
(a) Local backplane to local CPU #01
