Hello,
I am trying to make a simple PID controller for a rather slow process (loop rates < 1000 Hz), so I thought that I would just use a simple Labview VI (without realtime module). This seems to work fine and fast enough, but I would also like to save the input signal and the controller output to a spreadsheet or binary file to be able to analyse the performance of the controller.
I tried to add a 'write to spreadsheat' sub VI inside the controller loop to write the successive data values to a file (I used the append option to ensure that the previous values are not overwritten), but this limits the maximum loop rate to about 100 Hz. Does anyone know have a better idea? Maybe a VI alrready exists to do this?
Thank's a lot in advance!
