Table 54 – FilterAidDeviceType Attribute values for child nodes

BrowsePath	Description Attribute
2:Identification	Data for machine identification (OPC 40001-1).
ContainerOpen	Indicates that the filter aid reservoir is not closed.
DosageAmount	The amount of filter aid that is added per cycle.
FilterAidDeviceStatus	Describes the action performed by the dosage unit (see FilterAidDeviceStatusEnum).
FillingLevel	The filling level describes the amount of filter aid in the pre-storage reservoir.
Malfunction	Indicates that the filter aid device is malfunctioning. True in case of error. Malfunctions can be, for example, that there is no more filter aid or that there is a malfunction in the subsystems of the filter aid device.
4:MachineryItemState	StateMachine representing the operating state of the device (OPC 40001-1).
CompressedAirSupplyInterrupted	Indicates that the air supply is interrupted.
PowerConsumption	Describes the current power consumption of the filter aid device.
AirConsumption	Describes the compressed air consumption.
DosingRequested	Indicates that the filter system requests dosing.
AutomaticDosingEnabled	If enabled, the filter aid device is allowed to perform dosing automatically.

The components of the FilterAidDeviceType have additional references which are defined in Table 55.

If the filter aid reservoir is opened or closed, the event ContainerOpenConditionType will be triggered.

The event CompressedAirSupplyInterruptedAlarmType is triggered when the compressed air supply is interrupted.

When the value FilterAidDeviceStatus changes, the event FilterAidDeviceStatusChangedConditionType is triggered. The event contains a copy of the status value.

The server sends a MalfunctionAlarmType event when the Malfunction property changes.
