How can I access the signals and parameters of un referenced or Local configuration model

I want to Access, the Signals, Parameter, States of a un-referenced model or local configuration model ,

How can i do that?

Hi Manoj,

To access signals, parameters, and states in an unreferenced or local configuration model in Simulink, follow these methods:

• Log Signals: Right click the signal, select Properties, and check 'log signal'. Use the Simulation Data Inspector to view them.
• Programmatic Access: Use get_param and set_param to access and modify parameters:

param = get_param('model_name/block_name', 'ParameterName');
set_param('model_name/block_name', 'ParameterName', 'newValue');

• Initial States: Use Simulink.BlockDiagram.getInitialState('model_name').
• Workspace Export: In Configuration Parameters, enable 'States' and 'Signal logging' under Data Import/Export, and then run the simulation.
• Use find_system to locate blocks and signals.

blocks = find_system('model_name', 'Type', 'Block');

Ensure that the model is loaded with load_system('model_name') if unreferenced.

For more information, refer to the following documentation links:

• get_param: https://mathworks.com/help/releases/R2024b/simulink/slref/get_param.html
• set_param: https://mathworks.com/help/releases/R2024b/simulink/slref/set_param.html
• find_system: https://mathworks.com/help/releases/R2024b/simulink/slref/find_system.html
• Simulink.BlockDiagram.getInitialState: https://mathworks.com/help/releases/R2024b/simulink/slref/simulink.blockdiagram.getinitialstate.html

Hope this helps.
