How Do I connect Dashboard block to a constant block using command line.

I want to Simulate value of an input port using dashboard block e.g. Slider. I want to connect Slider block to a constant block. So if I change the value in slider, that will reflect to constant block, connected to the input port. I want to connect this slider block to the constant block using command line function. Is it possible?

Hi Pratik,

Did you figure out the answer to this question, yet? If so, could you please share it? I would like to know the solution too.

I have asked a similar question, here:

Hi Pratik,

You can find the step to connect dashboards block in the link below fomr the documentation:

https://www.mathworks.com/help/releases/R2019b/simulink/slref/simulink.hmi.paramsourceinfo.html?browser=F1help

In there you will see that you need to work with a Simulink.HMI.ParamSourceInfo object. Here I copy the specific workflow:

Connect and Configure the Slider Block

Use a Simulink.HMI.ParamSourceInfo object and the set_param function to connect the Slider block to the Gain parameter of the Mu block. To connect a parameter, the Simulink.HMI.ParamSourceInfo needs to specify the block path for the block that corresponds to the parameter and the name of the parameter.

slider_param = Simulink.HMI.ParamSourceInfo;
slider_param.BlockPath = Simulink.BlockPath('vdp/Mu');
slider_param.ParamName = 'Gain';

set_param('vdp/Slider',"Binding",slider_param)

Configure the scale for the slider for a range of 1 to 10 with a tick mark spacing of 1.

slider_limits = [1 1 10];

set_param('vdp/Slider',"Limits",slider_limits)

To remove the connection, do:

set_param('vdp/Slider',"Binding",[])

Hope it can help you.

Best,

Jesús
