Error -1073807265

[Double_D]

I am having multiple communication issues using a GPIB-ENET/100 to talk to a Keithley 6487 and a 6517A using LabVIEW 8.6.  I can communicate just fine from MAX, sending the *idn? or  read? queries and getting data back.  When using a simple program in LabVIEW, however, I encounter errors.  When I call VISA Open, I sometimes get no error or I get warning code 1073676413 (Session opened successfully, but the device at the specified address is not responding).  If I do a device clear after this, I get error -1073807265 (No listeners condition is detected (both NRFD and NDAC are deasserted) ).  Alternatively, I have seen error  -1073807264  after the device clear (The interface associated with the session is not currently the controller in charge). 

I had previously been using a Keithley KPCI-488 as the controller.  I was able to get LabVIEW to work at times with this device, but results were inconsistent and performance was sluggish, so I switched to the GPIB-ENET.  I uninstalled the Keithley software and deleted the KPCI-488 controller in MAX, hoping these steps would help, but they have not. 

I have attached the simple VI I am using for testing purposes.

Hello,

What version of NI-VISA are you using? Error 1073807264 is occurring because the GPIB device is not the controller in charge. Make sure you set the GPIB controller in charge in MAX. Please refer to the following KnowledgeBase for the Error 1073807265.

How Do I Fix Error: 1073807265 occurred at VISA Write

Thank you,

Simran, I have VISA version 4.4 installed.  I just installed the latest NI software from the 3rd quarter Developer Suite release.  The ENET controller is configured as the system controller in MAX (as it has always been).  BTW, I have noticed that if I start MAX with LabVIEW open, MAX runs very slow  or hangs.  Is this normal?

I changed the VISA resource input type for the VISA Open function from a string to an I/O name type.  I then entered GPIB0::22::INSTR into the control with an I/O Session class of GPIB Instr.  When I run the program with this configuration, VISA Open runs fine with no errors.  The following VISA Clear function, however, produces error -1073807265 (No listeners...) and this function and subsequent ones run very slowly (perhaps I need to decrease the GPIB timeout setting).  According to the linked KB article, I should use GPIB::22 for the resource input to VISA Open.  This doesn't work, producing error -1073807342 (Invalid resource reference specified.  Parsing error).

Simran,  I have things working now.  I installed LabVIEW on another PC and used the same hardware (ENET and instrument) with no problem.  When I ran the NI 488.2 tests in MAX on the original PC, I got error messages recommending reinstallation of the 488.2 software.  After doing this, communication under LabVIEW works on that machine as well.

Hello,

Thank you for letting me know and I am glad everything is working.

Hello, I've similar error code on Keithley 2400: 1073676413 (Session opened successfully, but the device at the specified address is not responding.) at VISA open. I've already installed KIOL-85C04. I can have successful communication with Keithley Communication software. But I want to extract data via LabTracer 2.9, but just failed with mentioned error. 

I can´t understand why my VISA is having problems.

The M2400 is connected via GPIB USB cable to my pc.

Should I try VISA run time 3.01?

with what file can I reinstall VISA layer?

I'm afraid, because I also use Keithley 6487, and don´t want to loose communication. Also have other instruments, but I'm not sure about if they use VISA for communcating.

I'll appreciate your advice, thank you for all.

According to Keithley (http://www.keithley.com/support/data?asset=56400), you should install the VISA Run-Time as a last resort. Under section 6 in the provided link, it is recommended to reinstall the 488.2 driver. Here is the latest driver from NI.
