MATLAB: How to use a Simulink.Signal Object as a parameter in a masked subsystem in R2017a

Question

I have a masked subsystem and I want one of the parameters to be a Simulink.Signal object but I keep getting an error stating that "Signal objects should only be created in the base workspace, data dictionary, or model workspace" 

 

Answer 1

This functionality is not supported at this time, however a workaround is to pass the Simulink.Signal object variable name as a string to the masked parameter.  Now, this parameter cannot be directly used to set the parameter of a block in the system that requires a signal object because it is a string.  To set block parameters in the subsystem using this mask parameter, I recommend using the Initialization callback with 'set_param' to set the corresponding block parameters from the mask.
