The CompactRIO reconfigurable embedded chassis, the integrated controllers and chassis, the Ethernet RIO chassis, the MXIe-RIO chassis, and the Single-Board RIO (sbRIO) devices have an onboard temperature sensor. Complete the following steps to read the temperature of the chassis or device.

  1. Configure the CompactRIO, Ethernet RIO, MXIe-RIO, or sbRIO system.
  2. Make sure the Chassis Temperature I/O item is added to the system.
  3. 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 system.
  4. Place an FPGA I/O Node on the block diagram of the VI.
  5. Click the element section of the FPGA I/O Node and select Chassis I/O (or Onboard I/O)»Chassis Temperature from the shortcut menu.
  6. Right-click the Chassis Temperature output of the FPGA I/O Node and select Create»Indicator from the shortcut menu.

The Chassis Temperature output returns 16-bit values for the temperature. You can convert this value into meaningful engineering units.
