Error 61211 Using a LabVIEW FPGA Reference

Issue Details

I have an FPGA VI that I open using the Open FPGA VI Reference function in my host code. When I execute the FPGA VI, it works fine: there are no errors, the code compiles and the data is correct. Nevertheless, when I use the FPGA reference, I get:

 

Error 61211

Possible reason(s):

LabVIEW FPGA: Multiple resources with the same name are present in this VI.  The Dynamic Mode of the FPGA Interface can only access a single resource of a given name.

 

Solution

  1. Make sure you are only using one Open FPGA VI Reference function in your code to access your FPGA resource/card.
  2. Make sure there are no controls and indicators with the same Label.
  3. Make sure there are no DMA FIFOs, or FPGA resources accessible through the host that have the same name.

Additional Information

This error shows when LabVIEW cannot know which resource it is supposed to use when there are multiple elements called by the same name. For example: two controls that have the same Label in the FPGA front panel.
