When you save a simulation file, any changes that you made to the graph, trends, and unmeasured load disturbance values are saved with the file. The next time you open MPC SimulatePro in context with a model that has a simulation file saved for it, the model is opened with the saved changes. In addition, the bias, amplitude, and time period previously used become the defaults.
Once MPC SimulatePro is running, you can open the same file or browse to the same block to select a different simulation model. You must select both a simulation model (to be tested) and a controller model (for control generation).
