Communicating between EtherNet/IP Units
Example: Communicating via EtherNet/IP Units Mounted to CPU Unit 1 and 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: “#11” (Unit address of EtherNet/IP Unit (Unit number: 1+10 hex))
(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)
Version Information
