Description
The Combo Box block allows you set the worthiness of a parameter to one of a few values. You are able to determine each value that is selectable its label through the Combo Box block parameters. Make use of the Combo Box block along with other Dashboard obstructs to create an interactive dashboard of settings and indicators for the model.
Double-clicking the Combo Box block doesn’t start its dialog package during simulation as soon as the block is chosen. To modify the block’s parameters, you can make use of the home Inspector, you can also right-click the block and choose Block Parameters through the context menu.
Linking Dashboard Blocks
Dashboard obstructs do not use ports for connecting to produce connections. In order to connect dashboard obstructs to factors and block parameters, utilize connect mode. Connect mode facilitates the entire process of linking dashboard obstructs in your model, particularly when you wish to link numerous obstructs at as soon as. You can also use the Connection table in the block dialog box once if you only want to connect a single dashboard block.
It is possible to change dashboard block connections in your model during normal and accelerator mode simulations.
Dashboard obstructs cannot hook up to variables before you update the model diagram. For connecting dashboard obstructs to factors or alter adjustable values between opening your model and managing a simulation, upgrade the model diagram making use of Ctrl+D.
To enter connect mode, pause for an unconnected dashboard block and click the Connect button that seems above it.
In connect mode, once you choose a number of signals or blocks, a summary of parameters and factors designed for connection seems. Decide on an adjustable or parameter through the list in order to connect to the chosen dashboard block. The Connect button above it to connect another dashboard block, pause on another dashboard block and click. Then, make an array of signals and obstructs in your model and select an adjustable or parameter to get in touch.
Once you complete linking the dashboard obstructs in your model, click on the Exit switch within the upper-right associated with canvas.
The message can be hidden by you shown on unconnected obstructs utilising the set_param function aided by the ShowInitialText block parameter. The message additionally vanishes whenever the block is connected by you.
Parameter Signing
Tunable parameters linked to dashboard blocks are logged towards the Simulation information Inspector, where you could see the parameter values along with logged sign information. You can easily access logged parameter information into the MATLAB В® workspace by exporting the parameter data through the Simulation information Inspector using the UI or perhaps the Simulink.sdi.exportRun function. To learn more about exporting data utilising the Simulation information Inspector UI, see Export Data through the Simulation information Inspector. The parameter information is saved in a Simulink.SimulationData.Parameter item, accessible as a component into the exported Simulink.SimulationData.Dataset .
Limitations
Except the Dashboard Scope block plus the show block, dashboard obstructs can simply hook up to scalar that is real.
You simply can’t utilize the Connection dining dining table to get in touch a dashboard block to a block that is commented away. You uncomment the block when you connect a dashboard block to a commented block using connect mode, the dashboard block does not display the connected value until the.
Dashboard obstructs cannot connect with signals inside referenced models.
Whenever you simulate a model hierarchy, dashboard obstructs inside referenced models don’t upgrade.
Dashboard obstructs usually do not help accelerator simulation that is rapid.
Some signals aren’t available during accelerator mode simulations. To see these signals employing a dashboard block, mark the signal for logging.
Whenever you specify a block parameter value by indexing a adjustable array, the parameter will not come in the bond dining dining table. For instance, a block parameter thought as engine(1) utilizing the engine that is variable perhaps maybe not come in the dining dining table.
The indexed value to a scalar variable, such as engine_1 to access the parameter in the Connection table, assign . Then, make use of the scalar variable to determine the block parameter.
Whenever a dashboard is connected by you block to a variable or parameter during simulation, the info for that adjustable or parameter isn’t logged to your Simulation information Inspector. To log adjustable and parameter information to your Simulation information Inspector, link the dashboard block to your adjustable or parameter ahead of simulation.
Once you simulate a model in outside mode aided by the Default parameter behavior set to Inlined, dashboard obstructs can seem to alter parameter and adjustable values. Nonetheless, the modification will not propagate into the simulation. For instance, Gain blocks display modifications designed to the Gain parameter utilizing the dashboard obstructs, however the Gain value found in the simulation doesn’t alter.
