Enabled Subsystem

Subsystem whose execution is enabled by external input

  • Library:
  • Simulink / Ports & Subsystems

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 Enable Subsystem blocks to model:

  • Discontinuities

  • Optional functionality

  • Alternative functionality

Ports

Input

expand all

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 get signals from the local environment.

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

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

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

Output

Placing an Outport block in a subsystem block adds an output port from the 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: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated | bus
