Configure signal logging programmatically (Simulink)

57 次查看(过去 30 天)
I have a model (inherited) that has over 200 signals set to log. I would like to remove all of these signals from logging and then add my own, programatically.
I understand there's two modes of signal logging: "Log all signals as specified in model" and "Override signals".
From my understanding, all the current programmatic ways of configuring logging, such as setting block parameter "DataLogging", will change the logging setup in the mode "Log all signals as specified in model". This is my current solution, although I don't know of a computationally efficient way to first remove all current signals set to log. The only method I can think of is to check all block and signal properties for "Log signal data" and "DataLogging" parameter values, which would be too computationally expensive. The other option is to manually right click and remove from logging the entire 200+ signals... Is there a better way?

You could re-set all those 200 signal loggings and then set what you want to log programingly.
lh=find_system(ModelName,'FindALl','On','type','line');
set(lh,'DataLogging',false);
