  1. I am experiencing numerous VISA Lock Errors (-1073807345) on resources I haven't explicitly locked. This is happening on TCPIP connections to keysight N6700 power supplies and keysight N5242 PNA fairly regularly. I have simultaneous loops in the application communicating to the different instruments, using a sequencer of sorts to pipe commands one at a time to each of my various loops. Has anyone seen the locking error pop before while not actually using the Lock and Unlock VIs? This issue has gotten worse lately and it has come time to find the root cause. My only thoughts are th

  3. When I was referring to a "Stop Move" I was referring to a SoftMotion move option. Just like a Straight-Line Move or Contour Move or Arc Move, the Stop Move can be created and have methods/properties called via invoke/property nodes. https://forums.ni.com/t5/NI-Labs-Toolkits/LabVIEW-NI-SoftMotion-Module-2009-SP1-Property-Invoke-Nodes/ta-p/3494129?profile.language=en ""Create—Use the Create polymorphic VI to create a reference to specific NI SoftMotion interface objects.

  4. It has been a while since I've used SoftMotion, but I recall running into similar issues. The way to mitigate this is to create a stop move, much like a straight line move or contour move except its purpose is to stop. You then start the stop move and the motor should stop with whatever settings you have created your stop move with. It doesn't seem very intuitive, but if I'm remembering correctly it worked pretty perfectly. It always seemed like stopping a straight line or any other move didn't stop the motor because it was telling it to stop the move after it was already finished. This s
  5. Some more info on how the cRIO is setup would be useful, such as screenshots from MAX Have you looked at this link and followed some of the steps on setup? http://www.ni.com/product-documentation/10555/en/
