8 CIP Message Communications
• Regardless of to which communications port (EtherNet/IP port 1 or 2) the data is actually input, you
can access both CPU Units (CPU#00 and CPU#01) that control the EtherNet/IP ports, via backplane
port.
Example:
Inputting an Ethernet Link object (class ID: F6 hex) through built-in EtherNet/IP port 1 of the destina-
tion NX701 CPU Unit, and reading the settings and status of built-in EtherNet/IP port 2
 NX1P2 CPU Unit
The network type number and the remote address are determined as shown in the following table
according to whether the route type is (1) a Unit on the CPU Rack or (2) a communications port on a
Communications Unit.
