Resettable Subsystem

Subsystem whose block states reset with external trigger

• Library:

• Simulink / Ports & Subsystems

• 

Description

The Resettable Subsystem block is a Subsystem block preconfigured as a starting point for creating a subsystem that resets the block states each time the control port receives a trigger signal. The behavior of the subsystem is controlled by a Reset block placed inside the subsystem.

Ports

Input

In — Signal input to a subsystem block

scalar | vector | matrix

Placing an Inport block in a subsystem adds an external input port to the Subsystem block. The port label matches the name of the Inport block.

Use Inport blocks to receive signals from the local environment.

Data Types: half | single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image

Reset — Control signal input to a subsystem block

scalar | vector | matrix

Placing a Reset block in a subsystem adds an external input port to the Subsystem block and changes the block to a Resettable Subsystem block.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Output

Out — Signal output from a subsystem

scalar | vector | matrix

Placing an Outport block in a subsystem adds an output port from the Subsystem block. The port label on the Subsystem block is the name of the Outport block.

Use Outport blocks to send signals to the local environment.

Data Types: half | single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image

Model Examples

Resettable Subsystems

Use two resettable subsystems to implement a ramp signal.

Open Model

Discrete and Continuous Resettable Subsystems

Compares the behavior of discrete and continuous resettable subsystems. After you run the simulation, one scope shows the results for the discrete resettable subsystem, and the other scope shows the results for the continuous resettable subsystem.
