Dials & Gauges Blockset

The Original Simulink Model

Consider a system in which a Constant block feeds into a Gain block, while a Scope block displays the output from the Gain block. All three of these blocks are part of Simulink.

If you simulate this system and double-click on the Scope block, then the Scope traces the value of its input signal over time. To change the value of the signal that feeds into the Gain block, you double-click on the Constant block, type a different number in the Constant value parameter field, and click on the OK or Apply button in the dialog box.

Replacing Simulink Blocks with Instrumentation

Using the Dials & Gauges Blockset, you can replace the Constant and Scope blocks from Simulink with instrument-like input and output. For example, a Generic Knob block can provide variable input to the Gain block, which passes its signal to a Lower Right display block.

When you simulate this system, the Lower Right block displays the value of the signal at that instant. To change the value of the signal that feeds into the Gain block, you use your mouse to adjust the needle on the Generic Knob block.
