Activity diagram and State machine diagram

Postby » Wed Mar 08, 2023 6:25 am

Hello all,

I would like to ask you something about "entry" activity of a state.

Let's say

I have 2 system as "A" and "B".

"A" system is my main system and I create a stm as "A_stm". But this stm needs some external signal to realize the transition between states. Let's say the required signal is "Start".

But this "Start" signal is managed by other system. So, the "B" system control the general situation and sends the "Start" signal to "A" system. I also prepare the proxy ports for that.

I create an activity diagram inside the "B System". Let's say its name is "Controlling". According the controlling result, "B System" can send to "A system" a "Start" signal.

My question is can I use "Controlling" activity diagram as a "Entry" function of "A system" ?

You can check the figure
