Connect Your CompactRIO System to Your Development Computer

Connecting to Power

Before wiring power, ensure that all DIP switches are in the OFF position. All DIP switches are in the OFF position when the chassis is shipped from NI. The default state for CompactRIO controllers with software switches instead of hardware DIP switches is OFF. These software DIP switches will be available later in Measurement & Automation Explorer (MAX) under the System Settings tab.

Complete the following steps to connect a power supply to the controller:

  1. Ensure the power supply is not energized (in other words, not plugged into a power source) before connecting any wires.
  2. Remove the power connector from the front of your CompactRIO controller by loosening the two captive screws that hold it in place.
  3. Connect the positive lead of the power supply to the V terminal and the negative lead to the C terminal on the power connector that was shipped with your CompactRIO Controller. If you have a connector with more than two pins, connect the positive lead to either the V1 or V2 terminal, and connect the negative lead to either of the C terminals (these C terminals are internally connected to each other).
  4. Tighten the leads in the connector by turning the captive screws on the side of the connector and ensure the wires are snugly in place. See the following table for information on replacement power connectors for each CompactRIO Controller.

  1. Reattach the power connector to your CompactRIO controller.

For best practices with Electromagnetic Compliance (EMC) and grounding power to your target, check your target's Getting Started manual.

Installing C Series Modules

Complete the following steps to install a C Series Module in the chassis:

  1. Make sure that nothing is connected to the module before inserting into the chassis. Because C Series Modules are hot swappable, the chassis can be powered on when you install modules if the system is in a nonhazardous location.
  2. Align the C Series Module with a module slot in the chassis. The module slots are labeled from left to right starting with the number one.
  3. Squeeze the latches and insert the module into the module slot.
  4. Press firmly on the connector side of the C Series Module until the latches lock the module into place.
  5. Repeat these steps to install additional C Series Modules.

Connecting via USB or Ethernet

Starting with the NI LabVIEW 2014 Real-Time Module, you can easily connect your CompactRIO Controller to a PC using a USB connection. Only CompactRIO Controllers running NI Linux Real-Time will support the USB connection. For more information, see Which Real-Time Targets Support Ethernet over USB? page. The USB device port is useful for configuring the target before deployment, debugging, viewing a console, or recovering the target if it goes offline. NI recommends using the USB connection when configuring for first use to avoid common networking problems.

To connect directly to a computer, connect one end of the USB cable provided with the hardware to a USB port on the target and connect the other end to a USB port on the PC. This USB connection is emulated as an Ethernet device. An automatic DHCP network is created over the USB device port, which allows for system updates apart from the physical Ethernet connection. The DHCP server assigns new target IP addresses from block 172.22.11.*. Once it's powered on, the target will show in MAX under Devices and Interfaces and Remote Systems.

Figure 5. Available network settings for a cRIO-9033 target with two physical Ethernet ports and one USB device port.

When it is time to deploy an application, a physical Ethernet port provides a more robust, distributed solution with higher throughput. To connect to an Ethernet network (hub, router, or local Network Interface Card), use a standard Category 5 (CAT-5) or better, shielded, twisted-pair Ethernet cable. Be sure to connect the Ethernet cable to the lowest numbered port on the controller to avoid networking issues. Lights will start blinking on the Ethernet port once communication is established, and the target will show in MAX under Remote Systems only.
