Persistent Variable Write

Write persistent variable value to target computer

  • Library:
  • Simulink Real-Time / Target Management /

  • Persistent Variable Write block

Description

The Persistent Variable Write block writes a value to the selected persistent variable when the real-time application starts and stops. The variable value persists when the target computer is shut down.

Use the getPersistentVariables function and setPersistentVariables function to access the persistent variable values on the target computer.

Ports

Input

The data type of the Persistent Variable Write block input port is inherited from its input signal. The signal can be any dimension.

The block can take a complex number. The complexity of the Persistent Variable Write block input port is inherited from its input signal.

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

Parameters
