Description

The For Iterator Subsystem block is a Subsystem block preconfigured as a starting point for creating a subsystem that repeats the execution during a simulation time step for a specified number of iterations. The number of iterations is controlled by a For Iterator block. Open model.

When using simplified initialization mode, if you place a block that needs elapsed time (such as a Discrete-Time Integrator block) in a For Iterator Subsystem block, Simulink® displays an error.

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 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus

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 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus
