Figure 10 shows an overview of the different ObjectTypes for the Weighing Technology devices and the references to the types from the Companion Specification for devices. Four subtypes of the ComponentType are defined:

  • FeederModuleType
  • PrinterModuleType
  • ScaleSystemType
  • ScaleDeviceType The entrypoint of a server is an instance of the ScaleSystemType or a ScaleDeviceType. The ScaleSystemType represents a multi-scale system and includes one ore more scales and has some common information (e.g. serial number). The ScaleDeviceType is abstract and only subtypes of it can be instantiated (see section 7.3). Both Types (ScaleDeviceType and ScaleSystemType) can optionally have an Object of the ProductionPresetType (see section 8.7) and/or an Object (called ProductionOutput) of the StatisticType.

Figure 10 shows the most important Object types used in the information model and the relations between them.
