Below is described a simple example of Device configuration. It configures all devices that have adapter name "DA Demo" and model "High Precision". As an additional condition these devices should have zero or one device item. The Device Items are filtered by an object class equal to com.prosyst.mbs.services.da.items.TransitionActuator and have tag "temperature". The device configuration adds a new tag "Kitchen" to the existing device tags.

The Device Item that matches the filter, is configured in the following way:

• its name is changed to "TransitionActuator Demo";
• new attribute is added to the existing Device Item attributes. This attribute has key "Int array" and the value is int[] with two elements – 3 and 4;
• an operation "start" is invoked that has two parameters of types:
  • com.prosyst.mbs.services.units.Quantity
  • long
