Interact with Signal Editor Tool from Signal Editor Block

The Signal Editor block Open Signal Editor button opens a version of the Signal Editor tool that is synchronized with the block.

1. To see the differences, create a model and add a Signal Editor block.

2. Create some signal data as MATLAB^® timeseries objects.

   1. Define the time values for the signal data.

      sampleTime = 0.01;
      endTime = 10;
      numberOfSamples = endTime * 1/sampleTime +1;
      timeVector = (0:numberOfSamples) * sampleTime;

   2. Create the data for the two scalar signals.

      signal_1 = timeseries(sin(timeVector)*10,timeVector);
      signal_2 = timeseries(rand(size(timeVector)),timeVector);

   3. Create the signals for the bus.

      busSignal.busElement_1 = timeseries(cos(timeVector)*2,timeVector);
      busSignal.busElement_2 = timeseries(randn(size(timeVector)),timeVector);

   4. Create a scenario.

      scenario = Simulink.SimulationData.Dataset;

   5. Add the signal and bus elements to the scenario.

      scenario = scenario.addElement(signal_1, 'signal_1');
      scenario = scenario.addElement(signal_2, 'signal_2');
      scenario = scenario.addElement(busSignal, 'busSignal');

   6. Save the scenario to a MAT file, myScenario.mat.

      save myScenario.mat scenario;

3. Double-click the block, in the File name parameter, browse to myScenario.mat and click Apply.

4. To open the Signal Editor tool, click the Open Signal Editor button . The Signal Editor tool opens populated with the scenario and a plotted signal.

   

5. To see the input properties for a signal, click a signal in the hierarchy.

   

   These properties correspond to the Signal Editor block parameter settings.

   Signal Editor Block	Signal Editor Interface
   Output as bus object	Output a bus signal
   Bus object	Select bus object
   Enable zero-crossing detection	Enable zero-crossing detection
   Form output after final data value by	Form output after final data value by
   Sample time	Sample time

6. Compare to the standalone Signal Editor tool with the same myScenario.mat file.

   

7. To apply changes between the Signal Editor block and the Signal Editor tool:

   • To change the active scenario in the Signal Editor tool, click the associated button in the hierarchy Active column and then click Save. Closing the tool updates then Signal Editor block.

   • Block parameters become read-only when you start the Signal Editor tool. To change control from the Signal Editor tool to the Signal Editor block, close the Signal Editor tool.

   • To see parameter changes for an active signal from the Signal Editor block in the associated Signal Editor tool, click the active signal in the signal hierarchy.
