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

This error shows when LabVIEW does not know which resource it is supposed to use because there are multiple elements called by the same name. For example: two controls that have the same Label in the FPGA front panel.
  • Make sure you are only using one Open FPGA VI Reference function in your code to access your FPGA resource/card.
  • Make sure there are no controls and indicators with the same Label.
  • Make sure there are no DMA FIFOs, or FPGA resources accessible through the host that have the same name.
