Automation Interface, Add-Ins and Tools / Re: Communication between Statemachines?

I believe that your problem is using the second state machine as entry behavior of a state. If you used a subMachineState (drag from the project browser while holding control and select instance) I think it would work.

Yes i want to simulate it as a entry state behaviour but not as a substatemachine. It is clear for me that it works if i model it as a substatemachine.Since I want to evaluate the simulation semantic/syntax of EA. Such as :in which cases does a simulation work, in which cases can the diagrams can communicate and how. But i think as long as i use it as an entry state behaviour the broadcastsignal command just works in one way.direction callee to caller.

There is no distinction between X and Y as which was originally called except when exiting. Yes, you can broadcast messages picked up by the calling state machine.

Here is again what i mean: a callee sends a signal to to its caller and the caller soes to next state.In same time the calle waits for a signal x. But this signal can not be activated from the caller.

As in the exemple in the first post. State machine 1 can not fire any trigger in statemachine 2. Those activate 1 and activate 2 must be triggered manually although the satet machine 1 broadcasts them. If it is possible and i can not model it, can you maybe show me an example showing the same case?

So, what is it that you want?

A statemachine(x) calls a statemachine (y). Can the statemachine x send a signal to statemachine y ?

In this case y can send a signal to x. But a signal sent by x can not received by state machine y.

Two (or more) state machines can communicate, but only if they are both running in the same simulation. In order to do that you need to initially start a setup behavior of some sort. You could do that with an activity that has two CallBehaviorActions or a subMachineState (which just means that the internal behavior of that state is specified by an external state machine)

I'm not sure I understand how that isn't what you want.

thanks, i get what you mean. But that is not what i want :-/

hey thanks for the answer.I have written to [email protected].

What do you mean exactly "a substatemachine for both of the machines you want to communicate"? so i should have a state machine(x) that launches this two machines(a,b) and each statemachine(a,b) from a substatemachine in x? Is the order of substatemachines relevant?


So it is not possible in the case that i have described? But only in the case you have described?

Thanks!

Thanks for the answer. I have already checked the example but its a very simple example since the signals will be sent in the same diagram.


so i upload 2 pictures describing the situation.

Actually the only question is = Can a state machine(x) send a signal to another statemache(y). If y is started as a behaviour from statemachine(x). Or can just statemachine(y) can send a signal to statemachine(x)?

Is bidirectional communication between statemachines in simulation possible?

I have tried to establish such a communication but i could not succeed.

Example: I have a Statemachine(x) and i call an another statemachine(y) in a state(x.a) of statemachine(x).Statemachine(y) execute sand  sends a signal(BroadcastSignal in state y.a) to statemachine(x) and the transition in statemachine(x.a to x.b) is triggered with this signal. Now Statemachine(y) is in state(y.a)and waiting for a signal to go to state(y.b). Statemachine(x in x.b) boradcasts a signal that should have been received by statemachine(y) but it does not.So the signal is lost and the statemachin(x) terminates.

So from this example i get the result that just a caller can receive a signal from called behaviour. But the called behaviour can not receive a signal from its caller.

Is there any possibility to establish such a connection? Can signals be send via classifiers with defined targets? Because both SendSignal action in activity diagrams and BroadcastSignal do not specifiy any special target behaviour that should receive the signal.

Any answer would be really helpful since Enterprise Architect is one of the software that  i evaluate the simulation capabilities in terms of my university thesis.

thanks in advance, Kesen

Not in the current version.

Thanks! That was really helpful

It's a simulation engine.

Have a look at the examples in the example model to see the supported constructs.

Thanks ive already looked at all examples, what i would like to know is if are there any other elements that are supported in the simultion other than in the examples.

Such as:

Writevariable action
valuespecification action
create/destroy object
exception handler action
also Time/call/change events or only Signal events etc..

Ive tried many of them but to be sure i just wanted to ask once more.

Is the Simulation in EA made with a simulation Engine or with generation of Code ?

PS: Are there any list of elements which are supported during simulation?
(which actions or events etc..)

Thanks!
