OPC UA for Process Air Extraction and Filtration Systems (PAEFS)
7.5.1 Overview
The FilterSystemType serves the purpose of extracting and filtering process gas, e.g., air. It consists of several filter units and other devices and components. It is formally defined in Table 22.

Attribute Description
2:Identification
Data for identification (OPC 40001-1): The FilterSystem should only have an Identification folder if the system as a whole is considered a machine. If the individual filter units are considered machines, the FilterSystem should not have an Identification folder.
The nominal airflow of the filter system is the value specified by the manufacturer which defines the nominal extraction capacity of a unit under operating conditions.
The marking on the type plate of the filter system regarding explosion protection.
The rated power of the filter system is the nominal electrical power of the unit under operating conditions specified by the manufacturer.
<FilterUnit>
All filter units of the system.
AirIntakeConnection
The connection to the ducting system from which the process gas enters the filter system.
AirOutletConnection
The connection to the ducting system to which the cleaned process gas leaves the filter system.
<FilterAidDevice>
All filter aid devices that are used on the server.
<Fan>
All fans used on the server.
<SafetySystem>
All safety systems used on the server.
<TemperatureRegulator>
All temperature regulators used on the server.
PowerConsumption
Contains information regarding the energy consumption of the filter system.
AirConsumption
Contains information regarding the consumption of compressed air of the filter system.
MaintenanceRequested
The maintenance request allows the manufacturer to inform the operator that the system requires maintenance. True = maintenance requested by system. False = no maintenance requested.
4:MachineryItemState
StateMachine representing the operating state of the filter system (OPC 40001-1).
ControlMode
Operating mode that describes whether the system can be controlled externally. Possible values are manual, auto and other.
Malfunction
Malfunction describes that the filter system has a collective fault message. True in case of error.
PressureLoss
Specification of the current total pressure loss of the filter system between the device intake connection on the raw gas side and the device outlet on the clean gas side.
The server sends a MalfunctionAlarmType event when the Malfunction property changes.
The MaintenanceRequestedConditionType is triggered when the MaintenanceRequested property changes.
The components of the FilterSystemType have additional subcomponents which are defined in Table 24.
