Parameter Writer

Write to a model instance parameter

• Library:

• Simulink / Signal Routing

• 

Description

The Parameter Writer block changes block parameter values in a referenced model by writing to instance parameters belonging to a Model block referencing a model.

Use the Parameter Writer block with the Initialize Function and Reset Function blocks to respond to events. For example, an event could be reading the value from a hardware sensor, and then updating a model parameter based on the sensor value.

Ports

Input

In — Parameter value

scalar | vector

Parameter value written to a block.

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

Parameters

Parameter owner block — Show the parameter owner block

none (default)

Show the parameter owner block whose parameter value this block is writing. To change the parameter owner block, select a block from the Parameter Owner Selector Tree.

Programmatic Use

Block Parameter: ParameterOwnerBlock

Type: character vector

Value: '' | '<model path/block name>'

Default: ''

Model Examples

Working with the Initialize Function, Reset Function, and Terminate Function Blocks

Use the Initialize Function, Reset Function, and Terminate Function blocks to read and write states in a Simulink model.

Open Model

Reading and Writing States with the Initialize Function and Terminate Function Blocks

In this example, the Initialize Function block uses the State Writer block to set the initial condition of a Discrete Integrator block to 10.
