Display color reflecting input value
Simulink / Dashboard
The Lamp block displays a color indicating the value of the input signal. You can use the Lamp block with other Dashboard blocks to build an interactive dashboard of controls and indicators for your model. You can specify pairs of input values and colors to provide the information you want during simulation.
Dashboard blocks do not use ports to connect to signals. To connect Dashboard blocks to signals in your model, use connect mode. Connect mode facilitates the process of connecting Dashboard blocks in your model, especially when you want to connect multiple blocks at once. If you only want to connect a single Dashboard block, you can also use the Connection table in the block dialog box to make the connection.
To facilitate understanding and debugging your model, you can modify Dashboard block connections in your model during normal and accelerator mode simulations.
To enter connect mode, click the Connect button that appears above your unconnected Dashboard block when you pause on it.
In connect mode, when you select one or more signals or blocks, a list of parameters and signals available for connection appears. Select a signal or parameter from the list to connect the selected Dashboard block. To connect another Dashboard block, pause on the block and click the Connect button above it. Then, make a selection of signals and blocks in your model, and choose a signal or parameter to connect.
When you finish connecting the Dashboard blocks in your model, click the Exit button in the upper-right of the canvas to exit connect mode.
You can hide the message shown on unconnected blocks using the
set_param function and the
Dashboard blocks can only connect to real scalar signals.
You cannot use the Connection table to connect a Dashboard block to a block that is commented out. When you connect a Dashboard block to a commented block using connect mode, the Dashboard block does not display the connected value until the you uncomment the block.
Dashboard blocks cannot connect to signals inside referenced models.
When you simulate a model hierarchy, Dashboard blocks inside referenced models do not update.
Dashboard blocks do not support rapid accelerator simulation.
Some signals are not available during accelerator mode simulations. To view such signals on a Dashboard block, mark the signal for logging.
Connection— Select a signal to connect and display
Select the signal to connect using the Connection table. Populate the Connection table by selecting signals of interest in your model. Select the radio button next to the signal you want to display. Click Apply to connect the signal. To facilitate understanding and debugging your model, you can connect Dashboard blocks to signals in your model during simulation.
States— Match values to colors to display
States match a display color to the value of the connected variable or parameter. Each state consists of a State and a Color.
State — Connected variable or parameter value that causes the Lamp block to display the specified color indication.
Color — Lamp color when the connected
variable or parameter value matches the corresponding
State value. You can select from a
palette of standard colors or specify a custom color with
[undefined] state specifies the color of the
Lamp block when the input value does not match any of the
values specified in the States table. Click the
+ button to add another state.
To programmatically specify the
Color parameter values for a Lamp
block, use an array of structures containing the fields:
Value — Scalar
double value corresponding to the
[r g b] vector with values between
the color for the Lamp to display.
lampState1.Value = 1; lampstate1.Color = [0 0 1]; lampState2.Value = 2; lampState2.Color = [1 0 0]; lampStates = [lampState1 lampState2];
|Type: structure array|
ColorDefault parameter specifies the color for
the Lamp block when the value of the connected signal
does not match any of the specified state values. Specify the
ColorDefault parameter as a
[r g b] vector with values between
Label— Block label position
Position of the block label. When the block is connected to an element in the model, the label is the name of the connected element.
|Type: character vector|
Dashboard blocks are ignored for code generation.
