How to make static variable in Simulink

I have several identical simulink models, where only the parameters vary:

Simulink block 1 uses the variables x.a{1}, x.b{1}, x.c{1} etc.

Simulink block 2 uses the variables x.1{2}, x.b{2}, x.c{2} etc

... up to Simulink block n using x.a{n} etc. The constants are used in gains, sums state space models etc.

How can i avoid hard coding the above numbers 1 through n in each and every block? I.e. i want Simulink block 1 to only contain the number 1 one time.

Hope this makes sense :)

You could use a masked subsystem and just have the block instance number n as a parameter. Then in the mask initialization function you can access the structure fields and map to some local variables.

Thanks for the hint! :)

Unless a variable is defined in a mask that variable will be the same one that's on your workspace, when your start the simulation simulink gets the values for each variable (for example one Constant block with the variable MyVar in the Value).

Ok thanks that makes sense :)
