**Property value**

[Double](https://learn.microsoft.com/dotnet/api/system.double)

The optional low low limit to test.

**Remarks**

The property is optional but at least one of the limit properties is required to apply limits to the alarm condition. For cases where an underlying system cannot provide the actual value of a limit, the limit property will still be provided, but will have its access level set to not readable. It is assumed that the limits are described using the same engineering unit that is assigned to the variable that is the source of the alarm. For rate of change limit alarms, it is assumed this rate is units per second unless otherwise specified.

### LowLowLimitNode

Gets the [OpcPropertyNode&lt;T&gt;](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcpropertynode-1/) of the [LowLowLimit](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opclimitalarmnode/members#lowlowlimit) property.

### SupportedLimits

Gets a combination of the values defined by the [OpcLimitAlarmStates](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opclimitalarmstates/) enumeration which defines the different limit states the [OpcLimitAlarmNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opclimitalarmnode/) supports.

**Property value**

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

A combination of the members defined by the [OpcLimitAlarmStates](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opclimitalarmstates/) enumeration.
