ERR6 during Scan read Keithley 2010..Please help

Hi Friends
i am facing a problem during a scan read of Keithley 2010 DMM i am getting an err6 which corresponds to File i/o error,
i am attaching the vi along with this, please can anyone go through this and help me work this out.
 
 i tried to debug by keeping break point at Scan read and found that the err 6 comes out of GPIB Recieve message in the Scan read vi
 
The flow of operation:
1) Initially i am doing a scan config which sets the start and stop channels and GPIB Adress
2) Next is the DMM Init for Keithley2010 DMM
3) Next i am doing a scan read which reads data from the DMM ( i am setting the count,delay,timer and other params here)
 
here in the 3rd stage i am getting an error output as ERR6, which corresponds to FileI/O error ( i have seen this descrption in the NI Help GPIB Error codes, is this correct)
 
i would be grateful if some one can go through this attachment and help me solve the porblem
 
Thanks in advance
 
Sandeep K Shyam

Hi Sandeep K Shyam
 
Err6 means timeout, no fileIO going on. So maybe you ask too much in a short time or maybe the data is not yet available after the standard timeout of 10 seconds.

Thanks Albert,

its interesting that the VI gives out some readings by replacing the ScanRead with the MultiRead VI,

ideally if we see the block diagram, we can hardly find any difference between these,

i would like to know if you can throw any light on this 🙂

 

Thanks

Sandeep K Shyam

scanning is using the multiplexer, multiread is reading one channel often
