Libraries:
DDS Blockset

Description

The DDS Blockset Library provides Take DDS Sample and Write DDS Sample blocks to help model DDS applications. The Take DDS Sample block receives samples from the DDS network and converts them to signals that can be used in the Simulink^® environment. The Write DDS Sample block converts signals from the Simulink environment to samples to send data into the DDS network. These blocks are preconfigured to be compatible with the DDS network and provide type checking functionality.

Ports

Input

Port_Enable — External enable signal

scalar

Enables the block to send a sample into the DDS network. For input values greater than 0 send is enabled. For input values less than or equal to 0 send is disabled.

Dependencies

To display this port, select the check box labeled Show enable port.

Data Types: double

Port_1 — Input signal

scalar | vector | matrix

Signal in Simulink environment. Signals are converted to samples that applications use to send data into the DDS network. The conversion preserves the value and data type of the original signal.

Data Types: bus

Output

Port_1 — Output DDS sample

scalar | vector | matrix

Sends samples into the DDS network.

Data Types: bus

Parameters

Show enable port — Display the enable port

off (default) | on

Select this check box to display enable port.

Programmatic Use

Block Parameter: ShowEnablePort

Type: character vector

Values: 'on' | 'off'

Default: 'off'

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

Code generation of DDS blocks requires an Embedded Coder^® license.
