Class implementing the UaObject interface for the ConditionType.
OPC UA Objects are used to represent systems, system components, real-world objects and software objects. They have the NodeClass Object. The detailed description of Objects and their attributes can be found in the general description of the Object node class.

The ConditionType defines all general characteristics of a Condition. All other ConditionTypes derive from it.
The FALSE state of the EnabledState shall not be extended with a substate machine. The ConditionType inherits all Properties of the BaseEventType.
SourceNode identifies the ConditionSource. If the ConditionSource is not a Node in the AddressSpace, the NodeId is set to null. The SourceNode is the Node which the condition is associated with, it may be the same as the InputNode for an alarm, but it may be a separate node. For example, a motor which is a variable with a value that is an RPM may be the ConditionSource for Conditions that are related to the motor, as well as a temperature sensor associated with the motor. In the former, the InputNode for the High RPM alarm is the value of the Motor RPM, while in the later the InputNode of the High Alarm would be the value of the temperature sensor that is associated with the motor.
Events are only generated for Conditions that have their Retain field set to true.
The NodeId of the Condition instance is used as ConditionId. It is not explicitly modelled as a component of the ConditionType. However, it can be requested with the following SimpleAttributeOperand in the SelectClause of the EventFilter:
Name | Type | Description |
---|---|---|
typeId | NodeId | NodeId of the ConditionType Node |
browsePath[] | QualifiedName | empty |
attributeId | IntegerId | Id of the NodeId Attribute |
See also ConditionType for a documentation of the complete Information Model.

Construction of the class ConditionType.
This constructor is used if the object is created based on an instance declaration of an object type. Since the only difference between the instance declaration object and the instance object are the node id, the pointer to the instance declaration node is used to get the attribute values other than NodeId from the instance declaration node.
The object is reference counted and can not be deleted directly. The reference counter is set to one after the object is created. If the object was successfully added to a NodeManager using the methods NodeManagerConfig::addUaNode or NodeManagerConfig::addNodeAndReference the NodeManager will release this reference during shut down. If the object was not added to a NodeManager, it must be deleted using the releaseReference method. If the interface pointer is used in other places, the availability of the object must be ensured by incrementing the reference counter with addReference when the pointer is stored somewhere and decremented with releaseReference if the interface pointer is not longer needed.
[in] | nodeId | NodeId of the new object |
[in] | pInstanceDeclarationObject | UaObject interface of the instance declaration node used to provide attribute values other than NodeId |
[in] | pNodeConfig | Interface pointer to the NodeManagerConfig interface used to add and delete node and references in the address space |
[in] | sourceNode | NodeId of the source node used for this condition object. Can be null if the source is not a node in the address space |
[in] | sourceName | Name of the source used for this condition object |

Construction of the class ConditionType.
This constructor is used if the object is not created based on an instance declaration. It defines the name and node id of the object. Additional language specific names and other attribute values can be set with set methods provided by the class.
The object is reference counted and can not be deleted directly. The reference counter is set to one after the object is created. If the object was successfully added to a NodeManager using the methods NodeManagerConfig::addUaNode or NodeManagerConfig::addNodeAndReference the NodeManager will release this reference during shut down. If the object was not added to a NodeManager, it must be deleted using the releaseReference method. If the interface pointer is used in other places, the availability of the object must be ensured by incrementing the reference counter with addReference when the pointer is stored somewhere and decremented with releaseReference if the interface pointer is not longer needed.
[in] | nodeId | NodeId of the new object |
[in] | name | Name of the new object. Used as browse name and also as display name if no additional language specific names are set. |
[in] | browseNameNameSpaceIndex | Namespace index used for the browse name |
[in] | pNodeConfig | Interface pointer to the NodeManagerConfig interface used to add and delete node and references in the address space |
[in] | sourceNode | NodeId of the source node used for this condition object. Can be null if the source is not a node in the address space |
[in] | sourceName | Name of the source used for this condition object |

Constructs an instance of the class ConditionType with all components.
[in] | pBaseNode | The "tree" of nodes that specifies the attributes of the instance and its children |
[in] | pFactory | The factory to create the children |
[in] | pNodeConfig | Interface pointer to the NodeManagerConfig interface used to add and delete node and references in the address space |
[in] | pSharedMutex | Shared mutex object used to synchronize access to the variable. Can be NULL if no shared mutex is provided |

virtual |
Applies a comment to a specific state of a Condition instance.
Normally, the NodeId of the object instance as the ObjectId is passed to the Call Service. However, some Servers do not expose Condition instances in the AddressSpace. Therefore all Servers shall also allow Clients to call the AddComment Method by specifying ConditionId as the ObjectId. The Method cannot be called with an ObjectId of the ConditionType Node.
Method Result Codes
ResultCode | Description |
---|---|
Bad_MethodInvalid | The method id does not refer to a method for the specified object. The MethodId provided does not correspond to the ObjectId provided. |
Bad_EventIdUnknown | The specified EventId is not known to the Server. |
Bad_NodeIdUnknown | The node id refers to a node that does not exist in the server address space. Used to indicate that the specified Object is not valid or that the Method was called on the ConditionType Node. |
serviceContext | General context for the service calls containing information like the session object, return diagnostic mask and timeout hint. | |
[in] | EventId | The identifier for the event to comment. |
[in] | Comment | The comment to add to the condition. |
Implements OpcUa::ConditionTypeBase.
OpcUa_StatusCode OpcUa::ConditionType::deleteBranch | ( | const UaNodeId & | branchNodeId | ) |
Deletes the branch identified by the branch NodeId.
[in] | branchNodeId | NodeId of the branch to delete. |
|
virtual |
Changes a Condition instance to the Disabled state.
Normally, the NodeId of the object instance as the ObjectId is passed to the Call Service. However, some Servers do not expose Condition instances in the AddressSpace. Therefore all Servers shall allow Clients to call the Disable method by specifying ConditionId as the ObjectId. The Method cannot be called with an ObjectId of the ConditionType node.
Method Result Codes
ResultCode | Description |
---|---|
Bad_ConditionAlreadyDisabled | The addressed Condition is already disabled. |
serviceContext | General context for the service calls containing information like the session object, return diagnostic mask and timeout hint. |
Implements OpcUa::ConditionTypeBase.
|
virtual |
Changes a Condition instance to the enabled state.
Normally, the NodeId of the object instance as the ObjectId is passed to the Call Service. However, some Servers do not expose Condition instances in the AddressSpace. Therefore all Servers shall allow Clients to call the Enable Method by specifying ConditionId as the ObjectId. The Method cannot be called with an ObjectId of the ConditionType Node. If the condition instance is not exposed, it may be difficult for a Client to determine the ConditionId for a disabled condition.
Method Result Codes
ResultCode | Description |

Set the entry to invalid.
This method can be overwritten by a derived class to set the internal state to invalid until the object gets deleted when the reference count goes to zero. This method is used if the object should be invalidated but can not be deleted since the lifetime is controlled by the reference count.
Reimplemented from ChainEntry.
UaStatus OpcUa::ConditionType::triggerBranchEvent | ( | ConditionTypeData * | pConditionTypeData, |
const UaDateTime & | time, | ||
const UaDateTime & | receiveTime, | ||
const UaByteString & | userEventId | ||
) |
Send event with event field data of the passed condition branch to the subscribed clients.
After setting the changed states of the condition branch this method is used to trigger the event notification that contains the snapshot of the new state of the condition branch.
[in] | pConditionTypeData | Event data of the condition branch to send a snapshot of the branch to the client(s). |
[in] | time | Time provides the time the Event occurred. This value is set as close to the event generator as possible. It often comes from the underlying system or device. |
[in] | receiveTime | ReceiveTime provides the time the OPC UA Server received the Event from the underlying device or another Server. |
[in] | userEventId | The server is responsible for generating a unique EventId for every event sent to the client. The SDK uses this parameter userEventId as part of the EventId but adds a unique part and the BranchId. The EventId is provided by the client in calls back to the server like in an alarm acknowledgment. The user specific part can be extracted from the EventId provided by the client by using ConditionType::getBranchByEventId() |
