Measuring different excitation voltages on a SCXI 1520

[the schmig]

I just reconfigured my strain gauge system and would like to adapt my old VI to this new config. 

Previously, I was measuring three strain gauges on three different SCXI modules all at 10V excitation.  Now, I am measuring two strain gauges at 5V and one at 10V, again, each strain gauge is on a seperate SCXI module.  The VI I made was simple enough using an input string and then setting the excitations with the parameter.vi.  What would be an efficient way to mark the first two modules for 5V exc. and the third for 10V?  Is there a way to bypass the need for the set parameter and just use the prescribed excitation I set in MAX for each individual module?

Any help would be much appreciated! Thanks.

Hello,

I must admit that I am slightly confused about what you mean.  What driver are you using, Traditional NI-DAQ or NI-DAQmx?  I assume that since you reference parameter.vi you are using Traditional NI-DAQ.  It's hard to say what the best way would be to set the excitation without seeing how you are using this subVI, but you could simply call the parameter VI once for each separate excitation that you are trying to set.  You could even do this in an auto-indexed for loop that uses arrays for the SCXI module list and the excitation list, so you do not have to have 3 separate parameter VIs.  This is just a suggestions.  If you want to post a portion of your code we may be able to make more specific recommendations.

Thanks,
