8-2-4 Route Path
The notation of the route path is different for communications on the built-in EtherNet/IP port and for
communication on an EtherNet/IP Unit. This section provides examples of route paths.
z Communicating between Built-in EtherNet/IP Ports
Example: Communicating between Built-in EtherNet/IP Ports on CPU Unit 1 and CPU Unit 2
• Network type number: “#02” (Output the command via EtherNet/IP port.)
• Remote address: Specify the remote IP address.
• Route path: \02\192.168.250.2
z Communicating from a Built-in EtherNet/IP Port to an EtherNet/IP Unit
Example: Communicating from the built-in EtherNet/IP port on CPU Unit 1 to CPU Unit 2 via the Eth-
erNet/IP Unit mounted to CPU Unit 2
(1) CPU Unit 1 to EtherNet/IP Unit 2
• Network type number: “#02” (Output the command via EtherNet/IP port.)
• Remote address: Specify the remote IP address.
(2) EtherNet/IP Unit 2 to CPU Unit 2
• Network type number: “#01” (Output the command via internal backplane port.)
• Remote address: “#00” (unit address of CPU Unit)
