Sporadic GPIB Read Error 6, Generic File I/O Error

[April H]

Hi,
I am trying to develop some simple (very simple) drivers for a GPIB controlled device, they work...sometimes. It seems that the problem I am having stems from a sporadic GPIB Read error 6, Generic File I/O Error. What does this mean? I can't reproduce the error. It just happens when things seem to be going fine and I'm just very confused. Can anybody help?

Hi,

Your Read function is probably timing out. Its aborting before its had a chance to capture the data. Look at what timeout value you have got wired to the timeout connector on the GPIB Read.

It might also be that you have the instrument in hold mode and not sending a trigger before performing the GPIB Read. Maybe one of your VIs is leaving it in this hold mode.

Regards
Ray.
