Tune “VariableName” of “From Workspace” block

7 visualizzazioni (ultimi 30 giorni)
Hello, I’m building a realtime app with simulink (Simulink Realtime + App Designer) and I want to be able to tune the data loaded by a “From Workspace” block before running the model. The issue is the block parameter is non-tunable so I get the following warning: “Parameter ‘VariableName’ of ‘Model’ is non-tunable but refers to tunable variables”… I read here (https://it.mathworks.com/help/slrealtime/ug/tuning-block-parameters-and-model-parameters.html) that one can tune non-tunable block parameters defining Simulink objects, which is exactly what I’m doing but it’s not working. Can anyone help? Thank you.

"Tune" usually means to change the value while the simulation is running, like a Gain value. What you need doesn't sound like "tune", but rather change the variable name before the simulation starts. To do that, you can use set_param('FromBlockPath','VariableName','MyVariable')
Or, you can change the value of the variable in the workspace, but not to change the variable name of the From Workspace block.

Thank you. I wasn’t aware I could pass an array as breakpoint input to a LUT to get an array as output. Cheers!
