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. |
