Generated base class for a AlarmConditionType.
This class contains the auto generated code for the object type AlarmConditionType representing an OPC UA condition type. This class is used to create the condition type and to create and represent the condition object in the server address space. It provides also the UaEventData interface for the access to event data containing the current state of the condition for events sent to the client.
The AlarmConditionType is an abstract type that extends the AcknowledgeableConditionType by introducing an ActiveState, SuppressedState and ShelvingState.
The AlarmConditionType inherits all Properties of the AcknowledgeableConditionType. The following states are sub-states of the TRUE EnabledState.
ActiveState when set to TRUE indicates that the situation the Condition is representing currently exists. When a Condition instance is in the inactive state (ActiveState when set to FALSE) it is representing a situation that has returned to a normal state. See getActiveState or setActiveState for more details.
The InputNode Property provides the NodeId of the Variable the Value of which is used as primary input in the calculation of the Alarm state. See getInputNode or setInputNode for more details.
SuppressedState is used internally by a Server to automatically suppress Alarms due to system specific reasons. See getSuppressedState or setSuppressedState for more details.
ShelvingState suggests whether an Alarm shall (temporarily) be prevented from being displayed to the user. It is quite often used to block nuisance Alarms (see also OpcUa::ShelvedStateMachineType).
The SuppressedState and the ShelvingState together result in the SuppressedOrShelved status of the Condition. See getSuppressedState or setSuppressedState for more details.
The optional Property MaxTimeShelved is used to set the maximum time that an Alarm Condition may be shelved. See getMaxTimeShelved or setMaxTimeShelved for more details.

) |
Constructs an instance of the class AlarmConditionTypeBase 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 |
UaNodeId OpcUa::AlarmConditionTypeBase::createBranch | ( | ) |
Creates a new branch from the current state and adds the branch to a list managed by the condition object.
ConditionType::getBranch() and ConditionType::deleteBranch() can be used to access or to delete the branch.
|
virtual |
ActiveState when set to TRUE indicates that the situation the Condition is representing currently exists. When a Condition instance is in the inactive state (ActiveState when set to FALSE) it is representing a situation that has returned to a normal state. The transitions of Conditions to the inactive and Active states are triggered by Server specific actions. Sub-Types of the AlarmConditionType will have sub-state models that further define the Active state. Recommended state names for LocaleIds are listed in the following table.
LocaleId | FALSE State Name | TRUE State Name |

|
virtual |
Returns the value of InputNode.
The InputNode Property provides the NodeId of the Variable the Value of which is used as primary input in the calculation of the Alarm state. If this Variable is not in the AddressSpace, a Null NodeId shall be provided. In some systems, an Alarm may be calculated based on multiple Variables Values, it is up to the system to determine which Variable’s NodeId is used.
|
virtual |
Returns the value of MaxTimeShelved.
If the optional MaxTimeShelved node has not been created, the value of the InstanceDeclaration node is returned.
The optional Property MaxTimeShelved is used to set the maximum time that an Alarm Condition may be shelved. The value is expressed as duration. Systems can use this Property to prevent permanent Shelving of an Alarm. If this Property is present it will be an upper limit on the duration passed into a TimedShelve Method call. If a value that exceeds the value of this property is passed to the TimedShelve Method, then a Bad_ShelvingTimeOutOfRange error code is returned on the call. If this Property is present it will also be enforced for the OneShotShelved state, in that a Alarm Condition will transition to the Unshelved state from the OneShotShelved state if the duration specified in this Property expires following a OneShotShelve operation without a change of any of the other items associated with the Condition.
|
virtual |
Returns the MaxTimeShelved node.
If the Variable has not been created yet, this method returns NULL.
|
virtual |
Returns the ShelvingState node.
If the Object has not been created yet, this method creates the node and returns it.
ShelvingState suggests whether an Alarm shall (temporarily) be prevented from being displayed to the user. It is quite often used to block nuisance Alarms.
|
virtual |
Returns the value of SuppressedOrShelved.
The SuppressedState and the ShelvingState together result in the SuppressedOrShelved status of the Condition. When an Alarm is in one of the states, the SuppressedOrShelved property will be set TRUE and this Alarm is then typically not displayed by the Client. State transitions associated with the Alarm do occur, but they are not typically displayed by the Clients as long as the Alarm remains in either the Suppressed or Shelved state.
|
virtual |
SuppressState is used internally by a Server to automatically suppress Alarms due to system specific reasons. For example a system may be configured to suppress Alarms that are associated with machinery that is shut down, such as a low level Alarm for a tank that is currently not in use. Recommended state names for LocaleIds are listed in the following table.
LocaleId | FALSE State Name | TRUE State Name |
---|---|---|
en | Unsuppressed | Suppressed |

Send event with current event field data to the subscribed clients After setting the changed states of the event this method is used to trigger the event notification that contains the snapshot of the new state of the condition.
[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. The EventId is provided by the client in calls back to the server like in an alarm acknowledgement. The user specific part can be extracted from the EventId provided by the client by using EventManagerBase::getUserEventId() |
