Error code：EABO - I/O operation aborted

[yhphycn]

I tried to run a vi. which is created by our group's former member to control keithley 2400.

I got a "EABO - I/O operation aborted"  error.  I don't know why, could someone give me suggestions for this trouble?

The labview I used is Labview 2019.

Thanks

Hi,

Have you tried the solutions mentioned here?

Hi yhphycn,

you are using some ancient GPIB functions in your VI.

Since 10+ years you should use VISA functions instead.

Have you tried to use the latest instrument drivers found in the IDNet for your device?

Thanks for your reply. I have not solve it.

Thanks for your reply. 

 You think the GPIB functions is very old?

So, I should change to visa now?

Another question, why it also doesn't work even I replace it with new GPIB commands?

Because something is wrong.

Could be software, could be hardware - you didn't tell so much about your setup so far…

Have you tried the Keithley2400 driver available in IDNet?

What is your hardware setup?

[yhphycn]

I use labview 2019. 

Keithley 2400 driver is installed. 

I use Keithley Instruments KUSB-488B with NI compatible driver. 

"Error code：EABO - I/O operation aborted" showing in the subvi.

The whole/main labview Vi file is created by other person a few years ago.

I just want to slightly modify it since I am not an expert in labview now. 

Please give me some suggestions. 

Thanks

Hi,

so you are using a Keithley USB-2-GPIB converter: in my experience you run into problems when using those old GPIB functions.

I recommend to use the most current version of the Keithley2400 driver with VISA function calls instead.

OK, thanks so much for your help.
