MATLAB script to print all Simulink manual switch positions

How to get the position of a single switch

get_param('MySimulinkModel/Manual Switch', 'sw')

This will return '0' if the switch is in the lower position and '1' if it is in the upper position.

Example how to print it:

fprintf('Manual Switch: %s\n', 'MySimulinkModel/Manual Switch');

Full example

The following MATLAB command will iterate all manual switches in the currently opened SIMULINK model recursively and print their current positions to the MATLAB command window.

% Find all Manual Switch blocks in the current model
current_model = bdroot;
manual_switches = find_system(current_model, 'BlockType', 'ManualSwitch');

% Output status of each Manual Switch block
for i = 1:length(manual_switches)
  switch_handle = get_param(manual_switches{i}, 'Handle');
  switch_pos = get_param(manual_switches{i}, 'sw');
  
  % Display block path and status
  if strcmp(switch_pos, '0')
    position = 'Lower Position';
  else
    position = 'Upper Position';
  end
  
  fprintf('Manual Switch: %s\n', manual_switches{i});
  fprintf('Status: %s (%s)\n\n', switch_pos, position);
end

Example output

Manual Switch: MySimulinkModel/Manual Switch
Status: 0 (Lower Position)

Manual Switch: MySimulinkModel/Subsystem/My second switch
Status: 1 (Upper Position)
