How to close FPGA reference out from different while loop

[mini09]

Hi Friends,

              I`ve different while loop which performs the FPGA read port on different loops I`ve the FPGA out on every terminal at the end of the while loop. I`ve just connected the merge error function in which all the error out of the FPGA are combined and given to simple error handler. How to close the FPGA Reference.

Can you attach your VI?  I'm not clear on what you mean.  Are you saying that you are using the FPGA reference which is passed into multiple loops, and then continuing the reference wire to pass the ref out of each of the multiple loops?

If that is the case, I don't believe you can't merge references like you can error clusters.  You will just need to wire one of the reference to the close FPGA VI.  Additionally though, I'd recommend that you use your error clusters in some manner to ensure data flow so that all the other loops stop first, and you are sure you are closing the reference after all the other loops are done with the ref.
