AggregatedDeviceHealth shall be the aggregation of the DeviceHealth of the AutomationComponent’s top-level Assets. The aggregation rules are defined as follows:

• If at least one top-level Asset has DeviceHealth set to Failure, the AggregatedDeviceHealth DeviceFailure bit shall be set.
• If at least one top-level Asset has DeviceHealth set to Check_Function, the AggregatedDeviceHealth DeviceCheckFunction bit shall be set.
• If at least one top-level Asset has DeviceHealth set to Maintenance_Required, the AggregatedDeviceHealth DeviceMaintenanceRequired bit shall be set.
• If at least one top-level Asset has DeviceHealth set to Off_Spec, the AggregatedDeviceHealth DeviceOffSpec bit shall be set.

AggregatedOperationalHealth shall be the aggregation of the OperationalHealth of the AutomationComponent’s top-level FunctionalEntities. The aggregation rule is defined as a logical OR of the OperationalHealth of all top-level FunctionalEntities.
