error -1073807339

[jayhawkeye13]

I am attempting to run a Keithley 2601A with labview using one of the examples provided by Keithley and am currently getting the error -1073807339. I had the error explained to me and it said the following: 

Error -1073807339 occurred at VISA Read in Keithley 2600 Series.lvlib:Initialize.vi->KE26XX Config Source & Measure.vi

Possible reason(s):

VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed.

I am new with Labview and the Keithley and would appreciate any help.

Hi Jayhawkeye13,

Are you using GPIB to communicate to the Keithley 2601A? If so what GPIB device are you using?

In Measurement and Automation be sure that under your GPIB device you can see the instrument as well.

Thanks!

I am currently using ethernet to communicate with the instrument

[jayhawkeye13]

It is a TCP/IP SOCKET connection to be specific.

Check to see if a termination character gets appended to each write. You can easily test whether this will help by using the VISA communicator in MAX and appending a \r or \b to a basic command such as *IDN?.

[jayhawkeye13]

I tried that and it didn't make much of a difference.  When I appended different letters to the *IDN? command, it gave me 7 instead of 6 as a return.  It didn't change after execution.

What is 'it' and where are you seeing 7? This is also the first mention of '6'. Attach some actual screen shots or code. Exactly what you are doing to troubleshoot is very unclear.

p.s. I had a typo in my earlier post. Instead of \b, it should be \n.

All that is showing is that you successfully wrote 6 characters. Did you do the most important part - click on the viRead tab and see if the instrument sent anything back?

Dennis is 100% correct!

You appear to be able to send data through the VISA session.  So you have made it about half of the way.  Now it's time to READ the Kiethley users manual to find the following information:

1. How to set the instrument to send and receive remote commands via Ethernet
2. What type of ethernet cable must be connected (patch or crossover) between the PC and the Instrument
3. What IP address is the instrument assignedc and is that consistant with the VISA session on the PC that is trying to talk to the instrument
