ERROR->1073807339 occured at VISA read in Labview

[CNRK]

Hi All,

I wrote a program to control the stepper motor. It was working fine before but suddenly it read the ERROR->1073807339 occured at VISA read. I checked using NI MAX which executes VISA write but not the VISA READ. It showed Return status as BFFF0015 during VISA READ. I checked the termination character as mentioned in the previous posts and everything looks fine. I've attached the labview files. Thanks in advance.

The question to ask is "what has changed between when it did work and now?"  Did you change any code?  If not, then something must have happened.  Loose cable, bad cable, damaged motor controller?

Hi,

I've not changed any codes. Even I checked the connectivity of the cables and it works fine.

I built an executable file for the analyser to measure the Magneto-optics property which was working fine (the stepper motor is a part of the analyser). But after this instant, even the .exe file is also not working. I doubt,even if someone tried to change the code, will it reflected in the .exe file? The .exe file and its source codes are untouched (not opened). I was planning to recode the analyser for some other measurements. So I made a copy (in different location) of the source code and tried to check whether it works on the code. It worked for some time but after that the copy and the.exe files are not working.
