Open Loop Detection on the NI 9234 in LabVIEW FPGA

Updated May 3, 2018

  • NI-9234


  • LabVIEW FPGA Module

Issue Details

  • How do I access the open loop detection in LabVIEW FPGA for the NI 9234 module?
  • There are no status check methods for Open Loop in the NI 9234 FPGA Method Node.


Open Current Loop Detection is not supported on the NI 9234. If you'd like to check this, consider another NI 923x module, or look into using a TEDS sensor. With a TEDS sensor, you can access information about the TEDS sensor that is connected, and compare it to what information is expected. 

Additional Information

For NI 923x modules that support Open Current Loop Detection, you can access the information through an FPGA Method Node calling the Check Cached Status method.
