**Property value**

[OpcNodeId](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeid/)

A null reference (Nothing in Visual Basic) if the event relates to the current state of the condition. Otherwise it identifies a previous state of this condition that still needs attention by an operator. If the current condition branch is transformed into a previous condition branch then the server needs to assign a non-null branch identifier. An initial event for the branch will generated with the values of the condition branch and the new branch identifier. The condition branch can be updated many times before it is no longer needed. When the condition branch no longer requires operator input the final event will have [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) set to false. The [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) property on the current event is true, as long as any condition branches require operator input.

**Remarks**

A condition's [IsEnabled](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isenabled) state effects the generation of event notifications and as such results in the following specific behaviour:

- When the condition enters the disabled state, the [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) property of this condition is set to the false enabled state by the server so indicate to the client that the condition is currently not of interest to clients.
- When the condition enters the enabled state, the condition is to be evaluated and all of its properties updated to reflect the current values. If this evaluation causes the [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) property to transition to to true for any condition branch, then an event notification is generated for that condition branch.
- The server may choose to continue to test for a condition while it is disabled. However, no event notifications will be generated while the condition is disabled.
- For any condition that exists in the address space the attributes and the following variables will continue to have valid values even in the disabled state; [EventId](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opceventnode/members#eventid), [EventTypeId](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opceventnode/members#eventtypeid), [SourceNodeId](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opceventnode/members#sourcenodeid), [SourceName](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opceventnode/members#sourcename), [Time](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opceventnode/members#time), and [IsEnabled](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isenabled). Other properties may no longer provide current valid values. All variables that are no longer provided will return a status of [BadConditionDisabled](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#badconditiondisabled). The event that reports the disabled state will report the properties as a null reference (Nothing in Visual Basic) or with a status of [BadConditionDisabled](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#badconditiondisabled).

### IsEnabledNode

Gets the [OpcTwoStateVariableNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opctwostatevariablenode/) of the [IsEnabled](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isenabled) property.

```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Property IsRetained As Boolean
```

</div>

**Property value**

[Boolean](https://learn.microsoft.com/dotnet/api/system.boolean)

The value true if the condition (or condition branch) is being in a state that is interesting for a client wishing to synchronize its state with the server's state. The logic to determine how this flag is set is server specific. Typically all active alarms would have the [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) flag set; however, it is also possible for inactive alarms to have their [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) flag set to true. In general events are only generated for conditions that have their [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) property set to the value true.

### IsRetainedNode

<div class="api-signature" data-lang="csharp">

```csharp
public OpcConditionRetainPolicy IsRetainedPolicy { get; set; }
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Property IsRetainedPolicy As OpcConditionRetainPolicy
```

</div>

**Property value**

[OpcConditionRetainPolicy](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionretainpolicy/)

One of the members defined by the [OpcConditionRetainPolicy](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionretainpolicy/) enumeration determining when the condition is automatically cleared from active client lists.

**Remarks**

**SDK Architecture Note:** The [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained) property indictates whether a condition appears in a client's active alarm view or is returned during a `ConditionRefresh` operation. By changing this policy, you control the underlying state machine that automatically recalculates the [IsRetained](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isretained)&gt; value when states like `ActiveState`, `AckedState`, or `LatchedState` change.

**Default Behavior:**

- Initializes as [EnabledOnly](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionretainpolicy/#enabledonly) for base [OpcConditionNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/).
- Initializes as [ActiveOrUnacknowledged](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionretainpolicy/#activeorunacknowledged) for [OpcAcknowledgeableConditionNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcacknowledgeableconditionnode/) and [OpcAlarmConditionNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcalarmconditionnode/).

**Compliance Rule:** Regardless of the selected policy, if [IsEnabled](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#isenabled) transitions to `Disabled` (False), the SDK will override the policy and strictly force `Retain = false` to comply with the OPC UA Part 9 specification.

Values for the [Quality](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcconditionnode/members#quality) can be any of the [OpcStatusCode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/) enumeration members as well as [Good](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#good), [Uncertain](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#uncertain) and [Bad](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#bad). These status codes are similar to but slightly more generic than the description of data quality in the various field bus specifications. It is the responsibility of the server to map internal status information to these codes. A server which supports no quality information returns [Good](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#good). This quality can also reflect the communication status associated with the system that this value or resource is based on and from which this alarm was received. For communication errors to the underlying system, especially those that result in some unavailable event fields, the quality is [BadNoCommunication](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcstatuscode/#badnocommunication).

### QualityNode
