Simulink - Outputting Signals successively

Hello everybody,

I am currently working with the Simulink Support Package for Android Devices. I am currently trying to output 2 signals with the scope block, one giving the user a target value and one using real-time data received from the sensors. I am wondering if it is possible to first display the target value graph starting from t0, then stop and then output the graph using real-time data. Currently both graphs are being plotted at the same time. From my understanding so far Simulink blocks have a constant signal output and there is no way of holding one signal back, they will always be displayed, starting at the current simulation time. I just wanted to ask if it is possible or if I am wasting my time trying to get this to work.

Thank you for your time!

Hi Leon,

From what I understand you want to send two signals alternatively to a same output port of your Simulink model. This is very well possible. For this you may use time signal as an input and control the output of the system as a function of the same using if conditions. You may use a pulse generator to generate the signals accordingly and program your system.

Alternatively, if you are using System Objects you may use the following to control various functionalities:

getCurrentTime(obj);

More information on using getCurrentTime() can be found in MATLAB Documentation here.
