Using multiple Event Listener
显示 更早的评论
Hello,
I've created a Simulink file which contains ~5 blocks with permanently changing data. Now, I'd like to create an event listener for each block.
I've generated the following code for each block's startfcn:
%The GUI handles are by default hidden, turn them on
set(0,'ShowHiddenHandles','on');
%Set up the arguments that will go into the block event callback listener
blk_SpO2 = 'Parameter_Final/SpO2';
event = 'PostOutputs';
listener = @Gruppeneinteilung;
%Create the listener
h = add_exec_event_listener(blk_SpO2, event, listener);
and
%The GUI handles are by default hidden, turn them on
set(0,'ShowHiddenHandles','on');
%Set up the arguments that will go into the block event callback listener
blk_BD = 'Parameter_Final/BD';
event = 'PostOutputs';
listener = @Gruppeneinteilung;
%Create the listener
h = add_exec_event_listener(blk_BD, event, listener);
...
My problem is, Simulink only creates a listener for one of the 5 blocks. If I delete that block another one will have a listener and so on. But I'm not able to execute all these listeners at the same time.
Is there anyone who can help me?
greetings, franzi

I think the listeners you create with add_exec_event_listener are similar to the listeners you create with addlistener in MATLAB. I think you want the equvilent of the listeners you get with event.listener in MATLAB. The difference being that the listener h that you are creating gets deleted when you overwrite h, but adding your second listener. I think you need to make h an array
h(1) = add_exec_event_listener(blk_SpO2, event, listener);
h(2) = add_exec_event_listener(blk_BD, event, listener);

Hello,
I have a problem which may be related to OP question, but may be slightly different as in the converse of OP.
I have one simulink model with one block containing ~48 changing signals, divided in 4 groups of 12.
I want to have 4 instances of MATLAB apps running simultaneously, each app monitoring 12 signals at a time.
Is this possible to have multiple listeners in one simulink model sending data to multiple MATLAB apps?
Thank you,
-Gheorghe S
