PXIe-8135 GPIB Scan for Instruments disabled

Hi,

I want to connect an electronic load to the PXIe-8135. I bought a Micro D cable and connect the load . When I open the Measuremanet Explorer, I open devices and see the PCI-GPIB. The self-test was successful. But the button "Scan for instruments" is not available. It is grey and has no funktion. Has anybody a solution? The settings from the PCI-GPIB are: GPIB-ID=GPIB0; Primary Adress 0; Secondary none; Timeout 13(10s); System-Controller and Autopolling are enabled; End of write enabled; Cable HS488 0; Parallelpoll 0 (2µs); Bus-Timing 2 (500ns).

regards

Does connecting a load automatically make the load an instrument???

I don't know. I think, there is an general problem maybe in the software configuration of the PXIe.

Hi Miks,

 

I've got some questions.

- What electronic load do You want to connect?

- Which GPIB-Card do You use?

- Don't You think You'll probably need a GPIB-Cable?

- Could You upload a screenshot of the MAX,

  and a MAX-Report?

Hi,

 

this sounds very similar:

Hi,

 

please excuse the long time without an answer. The problem still exists.

 

I followed your link. The adress of the host PC (xxx.102) is set under "security" of the PXIe8135's NI-VISA.

But the VISA interactive control as mentioned in http://digital.ni.com/public.nsf/allkb/ED3790E56FE969F8862575C30076063C?OpenDocument is not working. When I select the remote controler  (xxx.230) at "Machine" an error occurs.

The error massage and Ni-MAX is attached.

The NI-Server is running on the PXIe8135 and i think the version should be compatible, because they are the same (NI-Visa 15.0.0)

 

Regards

Hi,

 

could you check the instructions in this KB?

 

NI-VISA Error 0xBFFF00A7 from Real-Time Target - National Instruments

The instructions http://digital.ni.com/public.nsf/allkb/DAB1FE882B565F658625720A002900D7?OpenDocument were checked out, but the problem still exist.

To explain better:

I want to connect a Power Control Resource (PCE Chroce 63804) to the PXIe-8135 through a GPIB HS488 0 cable.

 

Through MAX it´s possible to see a GPIB resource, but it´s not possible to "Scan for Instruments", as in the picture 1, so it´s not possible to follow the normal Tutorial instructions (shown in http://www.ni.com/getting-started/set-up-hardware/instrument-control/gpib-connect).

 

Trying to communicate through VISA Interactive Control (version 15.0) results in Read Operation Error Hex 0xBFFF0015.

The adress of the host PC is set as written in http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/VISA-Access-to-the-resource-or-remote-machine... and the KnowledgeBase. (as in picture 2)

But the VISA interactive control as mentioned in the KnowledgeBase is still not working (as in picture 3).

I have exactly the same problem as Miks.

 

PXIe-8135 Controller, "Scan for instruments" button is grayed out, VISA interactive control throws error 0xBFFF00A7.

 

I have installed visa 15.5 but during the boot sequence it says "NI-VISA Server 15.0 started successfully." Could that be an indication that there is a version conflict? Re-installing VISA didn't change anything.

 

A solution would be nice...

 

By the way, USB and RS232 VISA resources work well.
