Real-Time Workshop

External Mode

In external mode, Real-Time Workshop establishes a communications link between a model running in Simulink and code executing on a target system. Further details on external mode are provided elsewhere in this documentation: Creating an External Mode Communication Channel contains advanced information for those who want to implement their own external mode communications layer. You may want to read it to gain increased insight into the architecture and code structure of external mode communications. In addition, Targeting Tornado for Real-Time Applications discusses the use of external mode in the VxWorks Tornado environment. The following discussion of external mode covers these major topics:

Introduction	Summary of external mode features and architecture
Using the External Mode User Interface	Describes all elements of the external mode user interface
External Mode Compatible Blocks and Subsystems	Types of blocks that receive and view signals in external mode
External Mode Communications Overview	Summary of the communications process between Simulink and the target program
The TCP/IP Implementation	Features, bundled targets, and techniques for using external mode protocol via TCP/IP
Limitations of External Mode	External mode restrictions imposed by the structure of a model
