Enabled Subsystem

Subsystem whose execution is enabled by external input

  • Library:
  • Simulink / Ports & Subsystems

    HDL Coder / Ports & Subsystems

  • Enabled Subsystem block

Description

The Enabled Subsystem block is a Subsystem block preconfigured as a starting point for creating a subsystem that executes when a control signal has a positive value.

Use Enabled Subsystem blocks to model:

  • Discontinuities

  • Optional functionality

  • Alternative functionality

For an explanation of the Enabled Subsystem block parameters, see Subsystem.

Ports

Input

expand all

Signal input to a Subsystem block, specified as a scalar, vector, or matrix. Placing an Inport block in a Subsystem block adds an external input port to the 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

An Enable block in a Subsystem block adds an external input port to the block and makes the block an Enabled Subsystem block.

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

Output

expand all

Signal output from a Subsystem block, returned as a scalar, vector, or matrix. Placing an Outport block in a Subsystem block adds an external output port to the block. The port label matches 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
