Table 54 – Conformance Units for Asset Management Basics

Category	Title	Description
Server	AMB Asset Identification	All manageable assets provided by the server have the “ProductInstanceUri” and optionally additional identification Properties. The Properties are either directly on the Object representing the asset or on the Identification Object grouping the Properties.
Server	AMB Configurable Asset Identification	All manageable assets provided by the server have the “AssetId” and optionally additional configurable identification Properties as writable Properties that store the configuration persistently, providing the written values also after a restart of the server. Servers shall support at least 40 Unicode characters for the clients writing this value. This means clients can expect to be able to write strings with a length of 40 Unicode characters into that field. The Properties are either directly on the Object representing the asset or on the Identification Object grouping the Properties.
Client	AMB Client Asset Identification	The client can make use of asset identification information and is capable to receive that information independent if it is provided per TypeDefinition, Interface or just as Properties on the instance or under the Identification Object and is able to deal with default values of the Properties.
Server	AMB Asset Discovery by ProductInstanceUri	All manageable assets are provided as AliasNames under to AssetsByProductInstanceUri using the ProductInstanceUri as AliasName. The AssetsByProductInstanceUri Object supports NodeVersion and ModelChangeEvents.
Server	AMB Asset Discovery by AssetId	All manageable assets supporting the AssetId Property are provided as AliasNames under to AssetsByAssetId using the AssetId as AliasName. The AssetsByProductInstanceUri Object supports NodeVersion and ModelChangeEvents.
Client	AMB Client Asset Discovery by ProductInstanceUri	The client can make use of the AssetsByProductInstanceUri discovery mechanism to discover the assets managed by the server or other, referenced servers. Whether the client uses the FindAlias method or browses the AliasNames is client-specific. The client is capable to manage Off-Server references in this discovery mechanism.
Client	AMB Client Asset Discovery by AssetId	The client can make use of the AssetsByAssetId discovery mechanism to discover the assets managed by the server or other, referenced servers. Whether the client uses the FindAlias method or browses the AliasNames is client-specific. The client is capable to manage Off-Server references in this discovery mechanism.
Server	AMB Asset Health Status Base	All manageable assets provided by the sever have the “DeviceHealth” variable.
Server	AMB Asset Health Status Alarms	All manageable assets provided by the server provide alarms with details of their fault indications. Optionally, the alarms are provided as Objects in the DeviceHealthAlarms folder.

Server	AMB Asset Health Status Alarm Categories	All manageable assets provided by the server provide alarms with a reasonable ConditionClassId.
Server	AMB Asset Health Tracking Overall Asset Status	All manageable assets provided by the sever having the “DeviceHealth” variable have the Historizing attribute of that variable set to true and the AccessLevel set to HistoricalRead.
Server	AMB Asset Health Tracking Events	The server supports access of the history of all alarms representing the details of fault indications of its assets.
Client	AMB Client Asset Health Status	The client can make use of the “DeviceHealth” variable and the alarms providing details on the fault indication.
Client	AMB Client Asset Health Tracking Status	The client can make use of the history of the “DeviceHealth” variable and the history of the alarms providing details on the fault indication.
Server	AMB Version Information	All manageable assets provided by the server have, depending on their nature, the Software- and or HardwareRevision Property and the RevisionCounter Property.
Server	AMB Operation Counters	At least one manageable asset provided by the server provides the OperationCounters Object and at least one operation counter.
Server	AMB DocumentationLinks Base	At least one manageable asset provided by the server provides the DocumentationLinks AddIn and have at least one link.
Server	AMB DocumentationLinks Edit Base	All manageable assets provided by the server provide the DocumentationLinks AddIn and have at least one link that can be edited by the user to provide user-specific links. The Browse- and DisplayName and the Description might be editable. The server supports links of a length of at least 255 chars.
Server	AMB DocumentationLinks Edit Advanced	All manageable assets provided by the server provide the DocumentationLinks AddIn and support the AddLink and RemoveLink methods. The server is capable to manage at least two links added via the AddLink method. The server supports links of a length of at least 255 chars.
Server	AMB Requirements	At least one manageable asset provided by the server provides the Requirements Object and at least one requirement.
Server	AMB Capabilities	At least one manageable asset provided by the server provides the Capabilities Object and at least one capability.
Server	AMB Classification	At least one manageable asset provides at least one HasDictionaryEntry reference to classify the asset.
Server	AMB Current and Future Maintenance Activities	All manageable assets provided by the server provide conditions with details of current or upcoming maintenance activities. Optionally, the conditions are provided as Objects in the DeviceHealthAlarms folder. The ConditionTypes used as maintenance activities implement the IMaintenanceEventType.
Server	AMB Past Maintenance Activities	The server provides capability to read the history of events and for all manageable assets provided by the server the history of all maintenance activities is provided. The ConditionTypes used as maintenance activities implement the IMaintenanceEventType.
Client	AMB Client Current and Future Maintenance Activities	The client can make use of the conditions provided as maintenance activities providing details on current and planned maintenance activities.
Client	AMB Client Past Maintenance Activities	The client can make use of the history of the conditions provided as maintenance activities providing details on the past maintenance activities.
Server	AMB Local Time	At least one manageable asset provided by the server provides the LocalTime Property.
Server	AMB Hierarchical Location Property	At least one manageable asset provided by the server provides the Location Property.
Server	AMB Hierarchical Location Objects	The HierarchicalLocations Object is provided with at least one location hierarchy and at least one manageable asset is referenced from that hierarchy with the HierarchicalContains Reference or a subtype.
Server	AMB Operational Location Property	At least one manageable asset provided by the server provides the OperationalLocation Property.
Server	AMB Operational Location Objects	The OperationalLocations Object is provided with at least one operational location and at least one manageable asset is referenced from that location with the OperationalContains Reference or a subtype.
Server	AMB Digital Location	At least one manageable asset provided by the server provides the DigitalLocation Property.
Server	AMB Sub-assets	At least one manageable asset provided by the server exposes at least one sub-asset as manageable asset. The sub-assets may be managed in another server.
Client	AMB Client sub-assets	The client can make use of the sub-asset hierarchy provided by the server and is capably to identify all sub-assets of an asset managed in the same server.
Client	AMB Client sub-assets remote	The client can make use of the sub-asset hierarchy provided by the server and is capably to identify all sub-assets of an asset managed in multiple servers.
Server	AMB Asset relations	At least one manageable asset provided by the server exposes a relation to another manageable asset other than containment (sub-asset). The referenced asset may be managed in another server.
