Let's open Object properties window by double clicking on it:

And let's create user-defined property - Number and make it's equal 1:

Now open Object properties for our Motor object and click Script's collection and add our script:

Now close Collection window and Object properties by clicking OK to confirm our changes. And now we can write our script:

 

Now we have Motor with setup fill property by script. To copy this Motor and bind fill color property to tags - State2, Speed2 and State3, State3 you no need to setup script for every Motor you only have to duplicate Motor:

 

And change Number property of the new Motor in the Property sheet:
