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)
• Destination address: Specify the destination IP address
c) Relay backplane to relay CPU #00
• Network type number: "01" (Output to Backplane port)
• Destination address: "#00" (CPU#00) Note: This is in order to output using the sender IP
address of the built-in EtherNet/IP port 1.
d) Relay CPU #00 to destination IP address
• Network type number: "02" (Output to the communications port)
• Destination address: Specify the destination IP address
