Connecting the cFP-20
xx
to a Network
Connect the cFP-20
xx
controller to an Ethernet network using the RJ-45
Ethernet port on the module. Use a standard Category 5 Ethernet cable to
connect the cFP-20
xx
to an Ethernet hub, or use an Ethernet crossover cable
to connect the module directly to 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 a 100 Mbps Ethernet, NI
recommends using a Category 5 shielded twisted-pair Ethernet cable.
The host PC communicates with the cFP-20
xx
over a standard Ethernet
connection. If the host PC is already configured on a network, you must
configure the cFP-20
xx
on the same network. If neither is connected to a
network, you can connect the two directly using a CAT-5 crossover cable.
If you need to build your own cable, refer to the
section of
Appendix B,
, for more information about Ethernet cable
wiring connections.
In order to configure the cFP-20
xx
, it must reside on the same subnet as the
host PC. If you want to use the cFP-20
xx
on a subnet other than the one the
host PC is on, first connect and configure it on the same subnet as the host
PC, then reassign a static IP address for the subnet where you want it to be
and physically move it to the other subnet. Contact your network
administrator if you need assistance configuring the host PC and cFP-20
xx
on the same subnet.
Wiring Power to the Compact FieldPoint System
Each cFP-20
xx
on your network requires an 11–30 VDC power supply.
NI recommends the PS-5 power supply for most Compact FieldPoint
applications. The PS-5 provides 24 V at 120 W and is designed to be
mounted on a DIN rail.
The cFP-20
xx
filters and regulates the supplied power and provides power
for all the I/O modules on the backplane. Refer to the documentation for the
individual I/O modules to determine whether they require any additional
power in your applications.
