Problem using GPIB and labview

Cris,

Attached you can see both errors.

Error is right here

Ok,

So we've narrowed it down to the Initialize VI from the driver as the first source of errors within the VISA CLR primative. I found this link http://digital.ni.com/public.nsf/allkb/874B379E24C0A0D686256FCF007A6EA0

that goes into details of why you receive Timeout Errors. Try to follow those instructions to see if any of those solutions work. This may be a long shot, but try to put a flat sequence structure after the open with a wait of 5000 (5 seconds) and pass the error wire and VISA Reference through the structure and out of structure to VISA Clear Error In and Reference In. Maybe it's not clearing the buffer in time.. Alternatively you could move the Timeout property node to directly after the VISA Open and see if that works..

[Ivanhe]

Not working any of that, bad luck here.

But really thanks for the support

Last thing I can think of is to use MAX and open up a VISA session to it from there and try a *CLS command to see if MAX VISA session gives you that same error..

Chris,

Not working 😞

Any other opinion? Would be appreciated

Try opening a VISA session to the instrument in MAX, as before, sending *IDN? and then doing a read to see if you get something back.  You should get a string that identifies your equipment.

Tomorrow i'll do in the lab.

After doing that, how i proceed?

[billko]

This is just to see if you are communicating at all with the instrument.

Cris,

After modifying some blocks and adding timeout the problem still was there.

Because that, i decide to move on and replace the ethernet -> GPIB adapter from tektroniks and instead of install USB -> GPIB adapter.

Boom, everything worked.

Thanks for your help.
