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 the host computer is on a network, you must
configure the controller on the same subnet as the host computer. If neither
the host computer nor the CompactRIO controller is connected to a
network, you can connect the two directly.
If you want to use the controller on a subnet other than the one the host
computer is on, first connect the controller on the same subnet as the host
computer. Use DHCP to assign an IP address or reassign a static IP address
for the subnet where you want it to be and physically move it to the other
subnet. The first time you configure the controller, you must also install
software on it. Contact your network administrator if you need assistance
configuring the host computer and controller on the same subnet.
Note You must connect Ethernet port 1 to configure the cRIO-9022. 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.
