Connecting the Controller to a Network
Connect the controller to an Ethernet network using the RJ-45 Ethernet port
on the controller front panel. Use a standard Category 5 (CAT-5) Ethernet
cable to connect the controller 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 100m. If you are using 100Mbps Ethernet, National Instruments recommends using a CAT-5 shielded twisted-pair Ethernet cable.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 using a CAT-5 crossover cable.
If you need to build your own cable, refer to the Cabling section for more
information about Ethernet cable wiring connections.
In order to configure the controller, you must connect it to the same subnet
as the host computer. 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. Refer to the Measurement & Automation
Explorer Help for more information about 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.
Wiring Power to the Controller
Caution
You must install the controller on a CompactRIO chassis and tighten the captive screws before you apply power to the controller. Installing the controller while power is applied to it can cause damage to the chassis. The controller requires an external power supply that meets the
specifications in the Power Requirements section. The controller filters and
regulates the supplied power and provides power for all of the I/O modules
in the chassis. You can connect two power sources to the controller. The
controller draws power from the power source with the higher voltage. The
controller has one layer of reversed-voltage protection. The power source
cRIO-9002/9004 Operating Instructions https://www.wendangku.net/doc/0f16362027.html, you connect to the controller must provide an additional layer of
reversed-current flow protection. Complete the following steps to connect
power sources to the controller.
1.
Install a ferrite across the negative and positive wires for both the V1 and V2 terminals. Refer to Figure 4 for an illustration of this step.2.
Connect the positive lead of one of the power sources to the V1terminal and the negative lead to one of the C terminals.3.Connect the positive lead of the other power source to the V2 terminal
and the negative lead to one of the C terminals.
Note The controller draws power from either V1 or V2 depending on which terminal has a higher voltage. It does not draw power from both terminals.
Caution
The C terminals are internally connected to each other. Make sure to use
two power sources that have a common ground. Figure 4.
Wiring Power to the Controller
Powering On the Controller
Plug in each power supply to the CompactRIO system. The controller runs
a power-on self test (POST). During the POST, the Power, Status, and
User1 LEDs turn on. The User1 and Status LEDs turn off, indicating that
the POST is complete. If the LEDs do not behave in this way when the
controller powers on, refer to the Understanding LED Indications section.
Boot Options
You can configure the controller to launch an embedded stand-alone
application each time you boot the controller. Refer to the LabVIEW
Real-Time Module User Manual for more information.
Table1 lists the reset options available on CompactRIO backplanes, such
as the cRIO-910x devices. Use these options to determine how the
CompactRIO controllers, such as the cRIO-9002 and cRIO-9004
controllers, are reset in various conditions.

flash memory to the FPGA when
the controller powers on.
Autoload on Any Device Reset Loads the FPGA bit stream from
flash to the FPGA when you
reboot the controller either with or
without cycling power. Connecting Serial Devices to the Controller
The controller has an RS-232 serial port to which you can connect devices
such as displays or input devices. Use the Serial VIs to read from and write
to the serial port. For more information about the Serial VIs, refer to the
LabVIEW Help.

Safe Mode Switch
The position of the Safe Mode switch determines whether the embedded
LabVIEW Real-Time engine launches when the controller boots. If the
switch is in the OFF position, the LabVIEW Real-Time engine launches.
Keep this switch in the OFF position during normal operation. If the switch
is in the ON position when the controller boots, the controller launches only
the essential services required for updating its configuration and installing
software. The LabVIEW Real-Time engine does not launch.
Push the Safe Mode switch to the ON position if the software on the
controller is corrupted. If there is no software installed on the controller, the
controller automatically boots into safe mode regardless of the position of
the safe mode switch. The Safe Mode switch must be in the ON position to
reformat the drive on the controller. Refer to the Measurement &
Automation Explorer Help for more about installing software on a
controller and the reformatting the drive on the controller.
Console Out Switch
With a serial-port terminal program, you can use the Console Out switch to
read the IP address and BIOS version of the controller. Connect the serial
port on the controller to a computer. Push the switch to the ON position.
Make sure that the serial-port terminal program is configured to the
following settings:
?9,600 bits per second
