ProcessStateId contains a relating identification for the occurring ProcessStateMessage.

ProcessStateMessage contains the message of the current overall state of the scale.

ProductionPreset contains the production presets. See section 8.7 for the complete definition of the ProductionPresetType.

SystemState provides information about the current state of the scale system and methods for controlling it. PackMLBaseStateMachineType is defined in OPC 30050.

ProductionOutput defines the overall statistic for the scale production.

The modules (subdevices) of a scale system are aggregated in the SubDevices Object (see section 7.3 and OPC 10000-100).

The components of the ScaleSystemType have additional references which are defined in Table 16.
