Issue Details

I heard that NI Linux Real-Time devices can be shutdown by using software commands. Can I do the same for NI Pharlap Real-Time devices?


Pharlap controllers can be shutdown from a LabVIEW application running on the Pharlap target.

Use the Call Library Function with the following  parameters:
  • Library name or paths : ni_emb.dll
  • Function name: ShutDown


Additional Information

Since sudden lost of power supply can cause damage to the hard disk, it is highly recommended to use Reliance file system format instead of FAT. If the file system is Reliance, there is no risk of damage to the controller because it is used in the embedded system to save data even if a power loss occurs.

Please refer to the link below on how to change the file system format on Real-Time PXI/PXIe controller.
