How can I control signal logging in referenced models?

AFAIK, the only way to control signal logging in a referenced model is by right clicking on the model block and pulling up the Model Reference Signal Logging dialog. Is there a way to control signal logging in the referenced model programatically? Can it be done through model arguments so as not cause a rebuild?

Try this:

Z=get_param('YourModel/BlockName','PortHandles');
set_param(Z.Outport, 'DataLogging', 'on');

Where: YourModel is your simulink model name and BlockName is name of block which output signal you'd like to log.

I don't think this can work when the block in question is a Model Reference and I'm trying to control the logging of signals inside the referenced model.

Phisically go to the block inside referenced model. Next find a handle to this block via

H=get_param(gcb,'Handle);

then

Z=get(H,'Porthandles');
set_param(Z.Outport, 'DataLogging', 'on')

it should work now.

This would work for one reference, but doesn't provide independent control over multiple references to the same model, such as can be achieved using the Model Reference Signal Logging dialog.
