Real-Time Workshop User's Guide

Compatible Blocks

In external mode, you can use the following types of blocks to receive and view signals uploaded from the target program:

• Scope blocks
• Blocks in the Dials & Gauges Blockset
• Display blocks
• To Workspace blocks
• User-written S-Function blocks

An external mode method has been added to the S-function API. This method allows user-written blocks to support external mode. See matlabroot/simulink/simstruc.h.

• XY Graph blocks

In addition to these types of blocks, you can designate certain subsystems as Signal Viewing Subsystems and use them to receive and view signals uploaded from the target program. See Signal Viewing Subsystems for further information.

External mode compatible blocks and subsystems are selected, and the trigger is armed, via the External Signal and Triggering dialog box. For example, Figure 5-7 shows two Scope blocks, a Display block, and a Signal Viewing Subsystem (theSink). All of these are selected and the trigger is set to be armed when connected to the target program.
