Simulink Stateflow execution of commands without prefixes

In a stateflow chart state such as the one above, where there is an algebraic command without an 'en:' , 'ex:' or 'du:' what will the state do.

The example above has the command Tmr = Tmr + 1 without a prefix. Say the exit state relies on Tmr being greater than 5, and it enters the state at 0. Will the Tmr execute only on entry, such as with 'en:' prefix, or will it function like 'du:'.

I also have a follow up question of if it does execute like the prefix 'du:' would imply. What determines the time between each execution?

Hi Joshua,

These will be treated as a combined entry/during action:

You can specify the rate for the chart in Modeling -> Chart Properties or it will try to inherit its rate from the solver settings or connected blocks/signals.
