The data type of Data Store Memory 'LEDON' used by a Chart cannot be set to 'auto' and must be known prior to type propagation. Please explicitly enter the data type in the Data Store Memory dialog.

Design stateflow, If engine speed is less than threshold1, switch off the LED. Blink LED on and off (On for 0.5 sec and Off for 0.5 sec) if the engine speed is greater than threshold1 but less than threshold2. Blink LED on and off (On for 1 sec and Off for 0.5 sec) if the engine speed is greater than threshold2.
I treid adding Data Store Memory but it is throwing the following error.

Component:Simulink | Category:Block error
I have tried designing it to some extent and the snapshots of model are attached here.

It seems like Simulink does not know the data type and wether it is a real variable or complex.
Try specifying it like that:

And the Data Type, I went with "single" as an example here, but you can use boolean or uint if you are only using on/off states for that variable.
