The first message is what am i am trying to do if you open .vi file in my first message of this chain you see that I have created .vi file for set up imputs and get the otputs of a dll file. This Vi is a part of the code no all there is more code that I need to excute with a PXI in real time the problem is that I get the error of the first message when I add the.vi file in the real time project? Do you think there is a way to execute the two models but no in the way you say me before i mean compiling de vi and mappling?
