Error -1074118124

[crsz]

Hello,

I'm getting "An error occurred while performing the switch operation 'Connect' for the following device 'VirtualDevice1'.
Could not perform the switching operation:
Details:An error has occurred while attempting to access device sw
Agilent34980A: IO error: .(Error = -1074118124)" while trying to switch a route from Teststand.

I am using Teststand 4.2 and NISE 3.0

I also want to mention that Switch configuration validation is Pass and if I use TestPanel it works. It doesn't work only from Teststand.

Please help,

Regards,

It appears you are making Switch Executive calls, but can you please explain how you are calling the switch functions in Test Stand (ie. LabVIEW calls, etc.).  Also ,can you run a NI Spy capture to see what VISA commands are sent out and the errors returned as well when you run the Test Stand code.

It could be that the Agilent Switch does not like the calls that are being made.  How is the Agilent Switch connected to your controlling PC (GPIB, USB, etc)?  Can you try to make the switch calls using LabVIEW calls (if this is an option for you)?

Hello,

Thank you for replying,

I make the switch calls using Teststand Switching panel (Step properties)

It works from Labview (switch_executive_getting_started.vi) and Switch Executive API

Route Validation is Pass (in MAX) and it works from MAX - Switch Executive Test Panel

I am using a GPIB-HS USB interface and Windows 7

I will post ASAP NI Spy capture - if I remember correctly it fails only at the step nise(switch....)

Best regards,

Cristian

And NI Spy capture...

Hi crsz,

Thank you for the reply.  This has been documented before encountered with Agilent switches when using the GPIB interface with SwitchExec Calls in TestStand.  Can you connect your device via USB to your host machine, or serial?  This has been known to be a workaround, and is worth a shot.

Hi crsz,

Another follow-up question.  Can you validate that the switch is able to work with the driver listed here: http://www.home.agilent.com/agilent/editorial.jspx?cc=US&lc=eng&ckey=1628832&nid=-34438.779160.02&id...

Hello Adam,

Sorry for my late reply, I had a few days off...

I will try it with the this drivers, but aren't they labview drivers? I intend to use IVI drivers...

Best regards,

Indeed they are LabVIEW drivers.  Can you provide a link to the IVI driver you are using?  Further, can you try to use your device via USB or serial?

Hello Adam,

I have tried it connecting 34980A directly to USB and it's working indeed.

Currently I am using IVI-COM, IVI-C Version 1.4.2.0 for 34980A because in my configuration I have a 34939A not supported by previous drivers. I have also tried  IVI-COM, IVI-C Version 1.3.10.0 for 34980A for NI Switch Executive but it was still not working.

Important thing is that when connecting 34980A directly to USB it works!

Another question - hope it is ok to ask in this post - not necessarily related to this error but related to 34980A IVI drivers. In my configuration I have a 34921A MUX card in slot 1. Why can't I see Channels "1043" and "1044" (in switch executive) for current measurements and why do I have "slot1com3" channel for this 34921A ? Channels "1041" and "1042" do exist though...

Driver setup is: dmm=true, slot1=34921A-2W, slot2=34932A, slot3=34939A

Thank you and regards,

Cristian

Hi Cristian,

Let's proceed by filing this question in a new post.  This will help to better document the threads for future reference.
