Reading the Temperature of an R Series Device

NI 784xR/785xR/786xR and NI 78xx devices have an onboard temperature sensor. Complete the following steps to read the temperature of the chassis or device.

1. Create a new project or open an existing project.
2. Configure the LabVIEW Project for your NI 784xR/785xR/786xR and NI 78xx device by completing the following steps:
   1. Right-click My Computer in the Project Explorer window and select New»Targets and Devices from the shortcut menu to display the Add Targets and Devices dialog box.
   2. Select the appropriate device under R Series and click the OK button.
3. Make sure the Device Temperature I/O item is added to the project.
4. Right-click the FPGA target in the Project Explorer window and select New»VI from the shortcut menu to add a new VI to the project.
5. Place an FPGA I/O Node on the block diagram of the VI.
6. Click the element section of the FPGA I/O Node and select Add New FPGA I/O.
7. In the New FPGA I/O dialog box, select Board I/O»Device Temperature from the Available Resources list, and click OK.
8. Right-click the Device Temperature output of the FPGA I/O Node and select Create»Indicator from the shortcut menu.

The Device Temperature output returns 16-bit values for the temperature. Refer to your device topic for information on converting this value into meaningful engineering units.
