Other Output

R2026b

Write to one or more output channels not handled by specific blocks

• 

Other Output block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Desktop Real-Time

Description

The Other Output block connects to and write to hardware sinks requiring specialized driver support that other Simulink^® Desktop Real-Time™ output blocks do not provide. The Other Output block is rarely used and only for a few drivers. For details, see the documentation for the driver that you intend to use.

If none of the available blocks, including Other Output, provide what you need, you can create your own I/O blocks to work with Simulink Desktop Real-Time applications. For more information, see Integrate C Code in Custom S-Functions.

Ports

Input

Data — Data to write to output channels

vector

The data type and range of the input value depend upon the capabilities of the board.

Data Types: single | double | int8 | uint8 | int16 | uint16 | int32 | uint32

Output

Missed Ticks — Missed tick count (optional)

double

In Connected IO mode, returns the number of timer ticks that your model lags behind the real-time kernel. When the model lags by more than Maximum missed ticks, the software reports an error and simulation stops.

Dependency

When you select Show “Missed Ticks” port, this port is visible.

Data Types: double

Parameters

Install new board — Register a board

< no board selected > (default)

When you click Install new board, the software displays a list of manufacturers of supported boards. When you select a manufacturer, the software displays a list of boards available from that manufacturer. When you select a board, the software adds the board to the list of registered boards and makes that board the current board.

By default, the initial selection in the list of registered boards is < no board selected >.

For more information about driver support for I/O boards, see Hardware Support from Simulink Desktop Real-Time.

Dependency

When you select a board in the list of registered boards, the Delete current board and Board setup buttons are available.

Programmatic Use

Block Parameter: DrvName

Delete current board — Delete the current board

(button)

To delete the current board, click this button. The initial selection of the list of registered boards changes to < no board selected >.

Dependency

To activate this parameter, select a board in the list of registered boards.

When you delete the current board, the Delete current board and Board setup buttons are no longer available.

Programmatic Use

Block Parameter: DrvName

Board setup — Set up the board

(button)

To set up the board, click this button.

A board-specific dialog box opens to set up the board. For more information, see the board manufacturer documentation.

Dependency

To activate this parameter, select a board in the list of registered boards.

To deactivate this parameter, click Delete current board.

Programmatic Use

Block Parameter: DrvAddress

Block Parameter: DrvOptions

Sample time — Sample time of block

0.1 (default) | double

Enter a value, in seconds, that represents how frequently you want the block to execute and interact with the I/O hardware. The block synchronizes your model with the real-time clock at this sample rate.

If you are using a fixed-step solver, enter the value that you entered as the Fixed step size configuration parameter or an integer multiple of that value.

Programmatic Use

Block Parameter: SampleTime

Maximum missed ticks — Number of timer ticks by which your model can trail the kernel

10 (default) | integer

In Connected IO mode, enter the number of timer ticks that your model can lag behind the real-time kernel. When the model lags behind by this number or fewer timer ticks, the software assumes that the lag is temporary. It allows the model to catch up, even if the model misses some ticks. When the model lags by more than this number, the software reports an error and simulation stops.

In Run in Kernel mode, the software ignores this value.

Programmatic Use

Block Parameter: MaxMissedTicks

Show “Missed Ticks” port — Send number of missed ticks to port Missed Ticks

'off' (default) | 'on'

In Connected IO mode, select this check box to send the number of missed ticks to output port Missed Ticks.

In Run in Kernel mode, the Missed Ticks port is zero.

Programmatic Use

Block Parameter: ShowMissedTicks

Yield CPU when waiting — Yield CPU while kernel waits for hardware

'off' (default) | 'on'

In Connected IO mode, select this check box to grant other programs more CPU time while the kernel waits for a response from the hardware.

In Run in Kernel mode, the software ignores this value.

Programmatic Use

Block Parameter: YieldWhenWaiting

Output channels — Channel vector that selects other output channels

1 (default) | vector

Enter a channel vector that selects the other output channels that you are using on this board. The vector can be any valid MATLAB^® vector form. For example, to select the first two other output channels, enter:

[1,2]

or

[1:2]

Programmatic Use

Block Parameter: Channels

Optional parameters — Specify optional parameters that the driver requires

0 (default) | vector

See the manufacturer data sheet for the required values.

Programmatic Use

Block Parameter: OptParam

Initial value — Specify the value that the channel generates before execution starts

vector

Enter the initial value for each output channel that you entered in the Output channels box.

Programmatic Use

Block Parameter: InitialValue

Final value — Specify the value that the channel generates after execution ends

vector

Enter the final value for each output channel that you entered in the Output channels box.

Programmatic Use

Block Parameter: FinalValue

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"sldrtlib/Other Output"

Example: add_block("sldrtlib/Other Output","myModel/myBlock",MakeNameUnique="on")
