[Simulink] Subsystems are locked and the parameters cannot be changed.

Hi,

I have a problem in Simulink model.

I put several same subsystems in one model (for example, named 'SS1' and 'SS2'), and I tried to change a parameter ('param') in the subsystems.

I wanted to set DIFFERENT value in each subsystem, SS1 and SS2, so wrote a code by using "set_param" command like this :

• set_param('…SS1/param', 'Value', '1')
• set_param('…SS2/param', 'Value', '2')

The paramter in SS1 can be set, but the command for SS2 generates an error like this :

• "SS2 is locked by SS1, so the parameter in SS2 cannot be changed."

How can I avoid this problem?

Best,
