Hello, I recently upgraded from LV 2010 to LV 2012 and am having troubles with my VISA Write calls. In 2010 my VISA Writes had no problems. I've attached a screen shot that shows the error message when in 2012.
I always get this error message and am having trouble finding a solution. I am sending GPIB commands to an HP8510 Network Analyzer. I was sending multiple commands per VISA Write but have decided to break out the commands so I have one command per VISA Write. That seems to have helped but I still keep getting this error message. I have made sure that I always do a VISA Close after my VISA Write/Reads. Could this be related to the version of VISA I have installed?
Here is my configuration:
I have tried using a VISA Clear before my VISA Writes but that doesn't help. If anyone has any ideas or some rules of thumb for using VISA Writes/Reads please let me know.
Thanks,
joe
