Simulink® Desktop Real-Time™

Description

Connect 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 for only 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. See Custom I/O Driver Basics for details.

Parameters

Install new board

Click this button to register a board with Simulink Desktop Real-Time.

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 >. When you select a board in the list, the Delete current board and Board setup buttons become active.

Delete current board

Click this button to delete the current board. The initial selection of the list of registered boards changes to < no board selected >, and the Delete current board and Board setup buttons become inactive.

Board setup

Click this button to set up the board.

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

Sample time

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

    Tip   If you are using a fixed-step solver, you must enter the value that you entered in the Fixed step size box in the Configuration Parameters dialog box, or an integer multiple of that value.

Maximum missed ticks

In Normal Mode, enter the number of timer ticks that your model can lag behind the real-time kernel. When the model lags by this number or less, the software assumes that the lag is temporary and 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 External Mode, the software ignores this value.

Show "Missed Ticks" port

In Normal Mode, select this check box to display the number of missed ticks as a block output.

In External Mode, The "Missed Ticks" port displays zero.

Yield CPU when waiting

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

In External Mode, the software ignores this value.

Output channels

Enter a channel vector that selects the analog output channels you are using on this board. The vector can be any valid MATLAB® vector form.

Optional parameters

Use this field to enter optional parameters that the driver requires.

Initial value

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

Final value

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