## 7.4 Subtypes of the ScaleDeviceType

In the information model different subtypes of a ScaleDeviceType are defined for the different scale types (see section 5.1.2). For many subtypes of the ScaleDeviceType, a subtype of the ProductType exists as a counterpart. The ProductFolder defined in the ScaleDeviceType is overload and can only contain the specific subtype of the ProductType or a subtype of them.

Figure 12 shows the main Object types used in the information model and the relations between them.
