cFP-2200/2210/2220
If you need to build your own cable, refer to the
Cabling
section for more
information about Ethernet cable wiring connections.
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 controller is connected to a network, you can
connect the two directly using a crossover cable.
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 to use the controller and physically move it
to the other subnet. The first time you configure the controller, you may
also have to install software on it. Refer to the
Measurement & Automation
Explorer Help
for more information about installing software on and
configuring the controller in Measurement & Automation Explorer
(MAX). Contact your network administrator if you need assistance
configuring the host computer and controller
on the same subnet.
Using Ethernet Port 2 to Connect the cFP-2220
to Other FieldPoint Systems on the Network
You can use Ethernet port 2 to connect the cFP-2220 to another system on
a private network. You must first configure the second system with a static
IP address in MAX. For information about using Ethernet port 2, go to
ni.com/info
and enter the infocode

.
Wiring Power to the cFP-22
xx
The cFP-22
xx
requires an external power supply that meets the
specifications in the
Power Requirements
section. The cFP-22
xx
filters and
regulates the supplied power and provides power for all of the I/O modules.
You must connect a power supply to at least one pair of V and C terminals.
Optionally, you can connect a power supply to the other pair of V and
C terminals. The controller draws power from the power supply with the
higher voltage. The controller has one layer of reverse-voltage protection.
Caution
In order to comply with standards and laws governing electromagnetic emissions
and compatibility, you must install the ferrite shipped with the controller. If you decide to
connect an optional second power supply, you must install a second, similar ferrite. You
can order the ferrite from
ni.com
. The ferrite is NI part number 711849-01.
