Is there any way to connect a dashboard block with a constant block by command ?

I want to connect a rotary switch block with a constant block by Matlab command. Is there any command to do that ?

Hi Abhijit,

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 Abhijit,

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.

Hello,

Have you got a solution for R2018a release because the above command line leeds to the error :

MWDashboardBlock block (mask) does not have a parameter named 'Binding'

Thanks
