Connecting the Controller to a Network
Connect the controller to an Ethernet network using Ethernet port 1 on
the controller front panel. Use a standard Category 5 (CAT-5) or better
Ethernet cable to connect the controller
to an Ethernet hub or a computer.
Caution
To prevent data loss and to maintain the integrity of your Ethernet installation,
do
not
use a cable longer than 100 m. If you are using 100 Mbps Ethernet, National
Instruments recommends using a CAT-5 or better shielded twisted-pair Ethernet cable.
If you need to build your own cable, refer to the
Cabling
section for more
information about Ethernet cable wiring connections.
Note
You will configure the IP settings and install software on the controller, as described
in the
Configuring IP Settings and Installing Software on the Controller
section, after
connecting power and powering the controller on.
The host computer communicates with the controller
over a standard
Ethernet connection. If neither the host computer nor the CompactRIO
controller is connected to a network, you can connect the two directly.
Note
You must connect Ethernet port 1 to configure the cRIO-9025. You cannot configure
the controller through Ethernet port 2.
In order to use Ethernet port 2, you must assign a static IP address to the
port using MAX. The IP address must be on a different subnet than the
IP address of Ethernet port 1. You cannot use DHCP with Ethernet port 2.
