Hi, model is using external DAC for data input into model. All works fine but no matter what sample time I set the ToWorkspace workspace variable only records that last 1000 data entries. These same points are displayed on the model Scope. I've tried changing Model simulation parameters (unchecking Limit data points to last), using different Format (Array, Timeseries etc), simulation run time set to inf. All to no avail. Tried Scope setting to scroll, which makes the display scroll after a while but when save scope data to workspace also set, the named variable only stores the last 1000 points. Any ideas?? Seem to have exhausted all avenues.
