LabVIEW RT cannot see FPGA PXI RIO board when usint 2 network cards.

[raeletro]

I'm using LabVIEW 7 with FPGA RIO Board on a PXI remote system running LabVIEW RT. The host PC is a DELL XEON 3GHZ running Windows XP with 1Gbytes of ram with two network cards. One card is connected to the PXI and the second to the normal computer network. When I connect the computer network cable to the second ethernet card, LabVIEW doesn't see the FPGA board. It shows FPGA DEVICE 78XX (NOT PRESENT). Max can see it and it looks fine.

For LV to being able to see a remote FPGA board it is necessary to configure remote VISA setting on the host computer in MAX.Go to MAX to the Software branch in the left window. Go to the VISA branch, in the right window go to the VISA options tab, and there to the VISA settings -> Remote branch. There you should see a list of remote VISA server addresses. Find the one from your RT system and ensure the checkmark in the box is set. Press the Apply button on top of the VISA Options window. Then restart LV if you have it still open. Now you should be able to see the remote FPGA board.

Thanks for the advise, but unfortunately I've checked the Visa settings and the PXI adress is there. However, LabVIEW still cannot see FPGA board when the host PC is connected to the second Ethernet card. If I unplugg this card,and the computer is connected only to the PXI chassi, then LabVIEW recognizes it. The problem is that I want to split some tasks to a second computer throught the network but in this case, LabVIEW doesn't acess FPGA.

My guess would be that both network cards are on the same subnet which can confuse Windows. Make sure that they are on different subnets and everything should work fine.
