Connecting The Cfp-21Xx To A Network; Wiring Power To The Compact Fieldpoint System - National Instruments Compact FieldPoint cFP-21 Series User Manual

Chapter 2 Installing Compact FieldPoint Hardware and Software

Connecting the cFP-21xx to a Network

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.

Wiring Power to the Compact FieldPoint System

cFP-21xx and cFP-BP-x User Manual
Connect the cFP-21xx 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-21xx to an Ethernet hub, or use an Ethernet crossover cable
to connect the module directly to a computer.
The host PC communicates with the cFP-21xx over a standard Ethernet
connection. If the host PC is already configured on a network, you must
configure the cFP-21xx 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
Appendix B, Specifications, for more information about Ethernet cable
wiring connections.
In order to configure the cFP-21xx, it must reside on the same subnet as the
host PC. If you want to use the cFP-21xx 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-21xx
on the same subnet.
Each cFP-21xx on your network requires an 11–30 VDC power supply.
NI recommends the PS-5 power supply for most Compact FieldPoint
applications.
The cFP-21xx 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.
Figure 2-16 shows the 6-pin screw-terminal power connector on the
cFP-21xx.
