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.
 Communicating with an EtherNet/IP Unit
Example: Communicating from the EtherNet/IP Unit mounted to CPU Unit 1 to CPU Unit 2 via the
EtherNet/ IP Unit mounted to CPU Unit 2
(1) CPU Unit 1 to EtherNet/IP Unit 1
• Network type number: “01” (Output the command via internal backplane port.)
• Remote address: “#01” (unit address of EtherNet/IP Unit)
(2) EtherNet/IP 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.
(3) 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)
 Communicating with a Built-in EtherNet/IP Port
Example: Communicating from the EtherNet/ IP Unit mounted to CPU Unit 1 to CPU Unit 2 via the
Built-in EtherNet/ IP port on CPU Unit 2
(1) CPU Unit 1 to EtherNet/IP Unit 1
• Network type number: “01” (Output the command via internal backplane port.)
• Remote address: “#01” (unit address of EtherNet/IP Unit)
