A number of the Target object functions produce event status. How can I use the MATLAB listener function to monitor event states？

As stated in Simulink® Real- Time™API Guide，“A number of the Target object functions produce event status. You can use the MATLAB listener function to monitor event states.”

But，How can I use the MATLAB listener function to monitor event states？

For example, I want to get the connect status of target.How do I code？

Hi Yuxuan,

I'm including some example code for how to do this.

tg = slrealtime;
listenerConnected = listener(tg,'Connected',@(~,~)disp('Connected to target computer'));
listenerDisconnected = listener(tg,'Disconnected',@(~,~)disp('Disconnected from target computer'));
listenerLoaded = listener(tg,'Loaded',@(~,~)disp('Loaded application on target computer'));
listenerStarted = listener(tg,'Started',@(~,~)disp('Started application on target computer'));
listenerStopped = listener(tg,'Stopped',@(~,~)disp('Stopped application on target computer'));
listenerStopped = listener(tg,'Stopped',@(~,~)disp('Stopped application on target computer'));

This code executes a series of target computer operations with pauses between the operations to provide time to observethe event status messages.

connect(tg);
load(tg,model);
start(tg);
stop(tg);
disconnect(tg);

Connected to target computer

Stopped application on target computer

Loaded application on target computer

Started application on target computer

Stopped application on target computer

Disconnected from target computer

Ultimately, there are a lot of other events you can use. To list the available events, use:

events(tg)
