Omron NX102-12 Series

Route Path Notation Examples

NX701 CPU Unit and NX102 CPU Unit
The route path notation is different for communications using the built-in EtherNet/IP port 1
(CPU#00) and for communications using the built-in EtherNet/IP port 2 (CPU#01).
This section provides examples of route paths.
This example explains communications via an NX-series CPU Unit.
1. Using the built-in EtherNet/IP port 1 (local CPU #00)
(Local CPU #00 to destination CPU #00)
(a)
IP address :
192.168.250.2

(Unit address 00 hex)
CPU#01
(Unit address 01 hex)

a) Local CPU #00 to destination IP address
•
Network type number: "02" (Output to the communications port)
• Destination address: Specify the destination IP address
Route Path : 02\192.168.250.2
2. Using the 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
•
Network type number: "01" (Output to Backplane port)
• Destination address: "#01" (CPU#01) Note: This is in order to output using the sender IP
address of the built-in EtherNet/IP port 2.
b) Local CPU #01 to destination IP address
• Network type number: "02" (Output to the communications port)
