Simulink R2020b DataStore Memory and String support. Cannot use a string as an Inital Value

In Simulink R2020b, I cannot use the DataStore Memory block with a string Initial Value although the DataType is set on "string".

The error message is the following : "Invalid setting in '<SYSTEM>/Data Store Memory' for parameter 'InitialValue'.

This should be support as per the documentation : https://fr.mathworks.com/help/releases/R2020b/simulink/ug/simulink-strings.html

Am I doing anything wrong ?

Hi @PLR,

To resolve the error, one workaround is to use the “Initialize Function” block to assign a string value to the “Data Store Memory” block. This works because the “Initialize Function” block is a preconfigured Subsystem block that executes during a model initialization event.

Kindly refer to the following images to understand how to use the "Initialize Function" block.

For more information on “Initialize Function” block kindly refer following MathWorks Documentation.

I hope this will be helpful.
