FieldPoint cFP-2120
Mount the Compact FieldPoint Backplane
You can mount the cFP-BP- x backplane on a 35 mm DIN rail, on a panel, or in a
standard 19 in. rack. Before using any of these mounting methods, record the
serial number from the back of the backplane.
Each set of mounting instructions in this document includes an instruction to
connect the protective earth (PE) ground terminal on the cFP-BP- x backplane to
the system safety ground. The backplane PE ground terminal has the following
symbol stamped beside it: . Connect the backplane PE ground terminal to the
system safety ground using 14 AWG (1.6 mm) wire with a ring lug. Use the
5/16 in. panhead screw shipped with the backplane to secure the ring lug to
the backplane PE ground terminal.

Caution If you are using UL Recognized I\O modules with the
Compact FieldPoint system, you must install the entire system in a
suitably rated, UL Listed NEMA or IP enclosure.
Caution NI recommends that you use one of the mounting systems
described in this document. If you decide to use a custom mounting
solution, make sure that the screws you use are short enough to fit in
the holes in the backplane. The screw holes are 5 mm (0.2 in.) deep.

install a cFP-CB- x connector block or other connectivity accessory for each I/O
module on the backplane. Use the connector socket to the right of each I/O
module socket.
Caution Do not insert or remove connector blocks or other
connectivity accessories while power is applied to them.
A. Wire field devices as described in the I/O
module and connector block

Connect the cFP-2120 to Your Network
Connect the cFP-2120 controller to an Ethernet network using the RJ-45 Ethernet
port on the controller. Use a standard Category 5 Ethernet cable to connect the
cFP-2120 to an Ethernet hub, or use an Ethernet crossover cable to connect the
controller 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, National Instruments recommends using a
Category 5 shielded twisted-pair Ethernet cable.
If the host PC is already configured on a network, you must configure the
cFP-2120 on the same network. If neither is connected to a network, you can
connect the two directly using a crossover cable.
In order for you to configure the cFP-2120, it must reside on the same subnet as
the host PC.

Wire Power to the Compact FieldPoint System
Each cFP-2120 on your network requires an 11–30 VDC power supply.
A. Connect the positive lead of the
primary power supply to one
of the V1 terminals and the
negative lead to one of the
C terminals.
B. If you are using a backup power
supply, connect the positive lead
to V2 and the negative lead to
one of the C terminals. The
cFP-2120 uses the power supply
with the higher voltage level.
V2 is isolated from the other V terminals.
C. Refer to the operating instructions for the power requirements of each I/O
module.
D. Use a separate power supply for each module that needs external power.
Caution Cascading power defeats isolation between the cascaded
modules.

Power Up the cFP-2120
Check the DIP switches on the controller, making sure that the RESET IP switch
is in the OFF position. Plug in each power supply to the Compact FieldPoint
system. The cFP-2120 runs a power-on self test (POST) that takes several
seconds. You should see the POWER and STATUS LEDs come on. After about
three seconds, the STATUS LED begins flashing steadily. The cFP-2120 is ready
to be configured.
If you have already assigned an IP address to the cFP-2120, the STATUS LED
turns off. The total boot time for a configured system is 10–15 seconds.
If the STATUS LED does not light up as described here, refer to the cFP-21xx and
cFP-BP-x User Manual at d:\docs\Network Modules, where dis the
letter of your CD-ROM drive.

the LabWindows/CVI instrument driver only if it finds the corresponding
development software installed.
B. Close all other applications.
C. Insert the National Instruments FieldPoint Software CD into the CD-ROM
drive on your computer.
D. Follow the onscreen instructions to complete the installation.
Note If the setup does not launch automatically, select Start»Run
from Windows, enter d:\setup, where dis the letter of your
