Detection of PXIe chassis (and the cards in it) without controller through bridging with PCIe - LabVIEW RT

[CyprienChauvet]

Hi,

I want to build soon a system with LabVIEW RT. For that I will have my RT target setup as follows :

- Computer target connected through PCIe to my chassis (which does not have any controller). The chassis is really acting more as an extension

- Inside the chassis I will have my PXIe card

Do you think that the target PC will be able to detect the chassis AND the PXIe cards in it without any trouble ?

Or do I need to setup a target as a PXIe chassis with a controller ?

Thanks for your help,

Cyprien

There are two questions here, and I just erased the answer I gave, which was to the "wrong" question.  If you are successful in getting your PC to communicate with your PXI Chassis directly, without having a PXI Controller present, you will almost certainly not be able to run LabVIEW RT.  A key element of LabVIEW RT is that a second processor (the Controller in a PXI system) is running a Real-Time Operating System, while the Host runs Windows, definitely not an RT-OS.

So even if you were successful in getting the PXI's backplane to route its signals to a card in the PC, you would not be running a two-processor LabVIEW RT Project (which needs that second processor).

Hi Bob,

I think I forgot to add something in the description of my system : I would have a host computer running Windows with LabVIEW RT module installed on it. The host computer would be linked to a RT target computer (configured following the instructions at this link : http://www.ni.com/pdf/manuals/371857f.pdf) through Ethernet, and the RT target computer connected to the PXIe chassis with my PXIe cards in it through PCIe.

I believe I need LabVIEW Real-Time Deployment License for PC to transform the PC target in a LabVIEW RT target ?

Also, if I forget the RT target PC and go with a PXIe chassis target with a controller in it, do I need the LabVIEW Real-Time Deployment License for PXI ?

LabVIEW Licensing is not my strong suit -- I'm at a University with a LabVIEW Academic Site License.  I would have thought that if you purchased LabVIEW with LabVIEW RT (or purchased a PXI system with LabVIEW RT on the Controller), that the RT license was implicitly included, but that's just me "being reasonable".  Talk to your NI contact people.

Okay, will do, thank you Bob !
