This information applies to all National Instruments RIO devices.

Issue Details

I have a system with an RIO device that I would like to target from a different system on the network. Is this possible?

Solution

You can access RIO devices running on a host system with networked systems if the host system is running the RIO server. 

LabVIEW Real-Time Systems

The RIO server is started automatically at system startup. 

Windows Systems

1.  The RIO server is not set to start automatically on system startup and must be started manually or set by a user to start automatically. The RIO server can be accessed in Windows XP and later by going to the Start Menu, and then navigating to Control Panel »Administrative Tools»Services. 

2.  In the Services window that opens, locate NI-RIO Server in the list, as shown below:



3.  Next, right-click on the NI-RIO Server and select Properties. In the window that opens, click the Start button to start the RIO Server, as shown below:​​



4. The RIO Server can also be set to run automatically at startup, by changing the Startup type to be Automatic, as shown below: 



Accessing a RIO Device From a System Running the RIO Server

1.  In the Project Explorer, right-click Project: Project_Name.lvproj and select New»Targets and Devices. Within the Add Targets and Devices dialog, select Existing target or device and thenSpecify a target or device by IP address. Then select the Networked Computer/Devicetarget, enter the IP address, and click OK. This will add the networked system containing the RIO target of interest to your project.



2.  To add the RIO target to the project, right-click on the Networked Computer/Device target that should now appear in the project, and select New»Targets and Devices. Within the Add Targets and Devices dialog, select Existing target or device. Then select the RIO target present in the networked system, and click OK. This will add the remote RIO target to your project. You can now access the remote FPGA from VIs running under your My Computer target.
