To demonstrate how to reduce signal line clutter, this example implements a model with multiple sensors and actuators. The system has two springs, dampers, and masses. A beam connects the two masses, as shown in this image.

Sensors read the displacement of the masses. The controller regulates the height at the center of the beamand levels the beam by computing the force the actuators must apply to the masses. The controller uses the height difference between the beam ends,, to level the beam.

Modelex_modeling_signalsrepresents the system.

To display signals after simulation, the model uses two Scope blocks. One Scope block shows the goal and actual beam levelness. The other Scope block shows the goal and actual position of the beam at its center, along with the actual beam position at both ends.

To reduce the number of signal lines, you can connect a viewer directly to signal lines or enable data logging for signal lines. By choosing a way to visualize simulation data without using a sink block, you can avoid extra signal lines.

Modelex_modeling_simulation_data_inspectorremoves the Scope blocks and related signal lines, then enables data logging for those signals.

To view the logged signals after simulation, open the Simulation Data Inspector by clicking the highlightedSimulation Data Inspectorbutton.

To further reduce the number of signal lines, you can group signal lines into a bus by using a Bus Creator or Out Bus Element block. All signal lines retain their identities when grouped in a bus and can be separated downstream from the bus.

By creating buses, modelex_modeling_composite_signalsprovides an even more readable system representation.

The simulation results remain the same after signals are grouped in buses. This example enables data logging for signal lines associated with busesx_sensorandgoalinstead of logging data individually for each of the signals in these buses.
