how to disable turn off signal in time scope using switch in simulink

Hello,

Is there a way to disable or turn off signal in time scope using a switch in simulink?

thank you

Hi Ecom,

Yes, you can disable or turn off a signal in a “Time Scope” using a switch in Simulink. Here’s how you can achieve this:

1. Place a “Switch” block in your Simulink model. This block will be used to control whether the signal is sent to the “Time Scope” or not.
2. Connect the signal you want to control to first input of the “Switch” block. The other input can be a constant value or zero that you want to use when the signal is turned off.
3. Now set the "Criteria for Passing" parameter in the “Switch” block. If you're using a logical signal (e.g., 1 for ON and 0 for OFF), set the threshold to 0.5 or an appropriate value based on your control signal.
4. Connect a control signal (such as a logical signal) to the control input of the “Switch” block. This control signal can be created using a “Constant” block, “Step” block, or any other block that can switch between inputs.
5. Finally, connect the output of the “Switch” block to the “Time Scope” input.

This setup will allow you to control whether the signal is visible in the “Time Scope” based on the value of the control signal. When the control signal meets the criteria set in the “Switch” block, it will pass the actual signal; otherwise, it will pass the default value.

To know more about the different blocks mentioned above, refer to the following documentation links:
