When the instance of the OPC server acts as an aggregation server, the Variable AggregatedServers lists the URIs of the servers that are aggregated by the server. When the server does not act as an aggregation server, the Variable AggregatedServers contains no element.

The Property Aggregating specifies if the OPC UA server is running as an aggregation server or not.

The Method GetTMCImplementedLevel returns the implemented level of the server.

Signature

GetTMCImplementedLevel (

[out]TMCImplementedLevelEnumerationTMCImplementedLevel

[out]MethodExecutionFeedbackType ExecutionFeedback

);

Argument	Description
TMCImplementedLevel	The server implemented level.
ExecutionFeedback	The extended feedback returning a detailed message in case of execution failure.

Method Result Codes

The TMCImplementedLevelEnumeration is formally defined in Table 47.

Table 47 – TMCImplementedLevelEnumeration Definition

BadNodeIdUnknown	See table 173 in OPC 10000-4 for the description of these result codes.
BadTypeMismatch
BadOutOfRange
BadNotWritable

Enumstring	Value	Description
Other	0	None of the below.
Essential	1	Essential server functionality
Advanced	2	Advanced features are implemented.

The present document requires that the OPC UA Server explicitly exposes the support (or lack thereof) for certain features that depend on the underlying capabilities of the computing hardware:

1. Method GetIOImage, 6.13.4.7;
2. Method GetLiveStream, 6.13.4.8;
3. Method GetRemoteConnection, 6.13.4.9;
4. Method GetScreenshot, 6.13.4.10;
5. Method GetSystemDump, 6.13.4.12;
6. Method InstallSoftwarePackageRemotely, 6.14.4.3;
7. Method TransferSoftwarePackageFromRepository, 6.14.4.5 and Method TransferSoftwarePackageToRepository, 6.14.4.6

The above mentioned features are not covered by the following definition of the TMCImplementedLevel and may be implemented or opted out for either the Essential or Advanced level.

An OPC UA Server implementing the Essential level, shall support the nodeset of the Object Types listed below, including relevant enumerations, data variable types, references and events required:

1. MachineModuleType, 6.1;
2. MachineModuleLiveStatusType, 6.2;
3. MachineModuleConfigurationType, 6.3;
4. MachineModuleSpecificationType, 6.4;
5. MachineModuleHistoricalRecordType, 6.5;
6. MachineModuleSetupType, 6.7;
7. MaterialLoadingPointType, 6.76.8 excluding the Variable TotalLoadedLot
8. MaterialStorageBufferType, 6.86.9;
9. MaterialRejectionTrapType, 6.10;
10. DefectDetectionSensorType, 6.11;
11. MaterialOutputType, 6.12;
12. ControlsHWType, 6.13;

ControlsSWType, 6.14;

1. TMCServerType, 0;
2. UIInformationType, 6.16;
3. UserInterfaceType, 6.17;
4. ProcessItemType, 6.18;
5. LogbookEvent, 6.19;

An OPC UA Server implementing the Advanced level, shall implement the Essential Level and additionally shall support the nodeset of the Object Types listed below, including relevant enumerations, data variable types, references and events required:

1. MachineModuleProductionType, 6.6;
2. MaterialLoadingPointType, 6.8 including the Variable TotalLoadedLot

The Method SetServerTime sets the time of the server. It is used for time synchronisation purposes.

Signature

SetServerTime (

[in]DateTimeToSet UtcTime

[out]MethodExecutionFeedbackType ExecutionFeedback

);

Argument	Description
DateTimeToSet	The time to set the internal clock of the server.
ExecutionFeedback	The extended feedback returning a detailed message in case of execution failure.
