Programming the CompactRIO Chassis FPGA LED (FPGA Interface)

The cRIO-910x Reconfigurable Embedded chassis and the cRIO-9072/9074 Integrated controller and chassis have an FPGA LED. You can use the FPGA LED to help debug your application or easily retrieve application status. Complete the following steps to configure the FPGA LED.

Note  The cRIO-9002/9004 embedded controller does not have an FPGA LED.

1. Configure the CompactRIO system.
2. Make sure the FPGA LED I/O item is added to the CompactRIO 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 CompactRIO 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»FPGA LED from the shortcut menu.
6. Right-click the FPGA LED input of the FPGA I/O Node and select Create»Control from the shortcut menu. When FPGA LED is TRUE, the CompactRIO chassis FPGA LED is lit. When FPGA LED is FALSE, the CompactRIO chassis FPGA LED is off.
