Control Scope Blocks Programmatically - MATLAB & Simulink (original) (raw)

This example shows how to control scopes with programming scripts.

Use Simulink Configuration Object

Use a Scope Configuration object for programmatic access to scope parameters.

Modify the title, axis labels, and axis limits
Turn on or off the legend or grid
Control the number of inputs
Change the number of displays and which display is active

Create a model and add a Scope and Time Scope block. Then, use get_param to create the Scope Configuration object myConfiguration.

mdl = 'myModel'; new_system(mdl); add_block('simulink/Sinks/Scope', [mdl '/myScope']); add_block('dspsnks4/Time Scope', [mdl '/myTimeScope']); myConfiguration = get_param([mdl '/myScope'],'ScopeConfiguration')

myConfiguration = Scope configuration with properties:

                            Name: 'myScope'
                        Position: [360 302 560 420]

                        TimeSpan: 'Auto'
           TimeSpanOverrunAction: 'Wrap'
                       TimeUnits: 'None'
               TimeDisplayOffset: '0'

               ShowTimeAxisLabel: 0
                   ActiveDisplay: 1
                           Title: '%<SignalLabel>'
                      ShowLegend: 0
                        ShowGrid: 1
            PlotAsMagnitudePhase: 0
                         YLimits: [-10 10]
                          YLabel: ''
                     DataLogging: 0
         DataLoggingVariableName: 'ScopeData'
      DataLoggingLimitDataPoints: 0
            DataLoggingMaxPoints: '5000'
         DataLoggingDecimateData: 0
           DataLoggingDecimation: '2'
           DataLoggingSaveFormat: 'Dataset'

Set a property.

myConfiguration.DataLoggingMaxPoints ='10000';

Find the Scope and Time Scope blocks.

find_system(mdl,'LookUnderMasks','on','IncludeCommented','on', ... 'AllBlocks','on','BlockType','Scope')

ans = 2×1 cell {'myModel/myScope' } {'myModel/myTimeScope'}

Find only Simulink Scope blocks.

find_system(mdl,'LookUnderMasks','on','IncludeCommented','on',... 'AllBlocks','on','BlockType','Scope','DefaultConfigurationName',... 'Simulink.scopes.TimeScopeBlockCfg')

ans = 1×1 cell array {'myModel/myScope'}

Find only the DSP Time Scope blocks.

find_system(mdl,'LookUnderMasks','on','IncludeCommented','on',... 'AllBlocks','on','BlockType','Scope','DefaultConfigurationName',... 'spbscopes.TimeScopeBlockCfg')

ans = 1×1 cell array {'myModel/myTimeScope'}
