Access via GPIB from real-time target.

[Pavgran]

Hello.

I use Kiethley 2400 Sourcemeter which connected to PXIe-8135 by GPIB and PXIe-4139. I use real-time module on it.

I can see Kiethley from Visa Ineractive Control in localhost and in PXIe.

When I launch LabView program from the host computer I can see VISA resources, but can't see my Real-Time device PXIe-4139. When I launch it from Real-Time target, I can see PXIe-4139, but I can't see VISA resources.

I've tried to do so http://digital.ni.com/public.nsf/allkb/01F9536A7A1D12A486256FF000561DA6 , but it hadn't help.

How can I access both devices from LabView?

Did you install VISA on your Real Time target?

Yes

I solved my problem.

The problem was because I entered adress of Kiethley like this: visa://NI-PXIe8135.../GPIB0::24::INSTR but when launch LabView program from Real-Time system I should write adress like this: GPIB0::24::INSTR.

But this adresses in my program I writed directly, because in the drop down list were not anything except "Refresh" and it confused me.
