You might find useful the documentation for logging signals:

I should try:
Connecting the signal to a To Workspace block, Scope block, or viewer. ... Results are visible during simulation. ...
(root-level Outport, and signal logging have visible result only at end/pause of simulation.)

I don't see any way to read stored value(s) from Scope.
I hoped that simout, generated by To Workspace, is changing during simulation. But it was refreshed only at pause and at stop.

Some additional idea to try?
James, thank you for your help too.
