SensorSetpointReadType ObjectType Definition – OPC UA for Process Air Extraction and Filtration Systems (PAEFS)

7.2 SensorSetpointReadType ObjectType Definition

The SensorSetpointReadType represents a process value and provides a setpoint for this value. It is formally defined in Table 15. A device is not required to provide a setpoint.

This type provides only read-access to the setpoint. Write-access is provided by SensorSetpointWriteType.

The component Variables of the SensorSetpointReadType have additional Attributes defined in Table 16.

IsActiveSetpoint	Indicates that the setpoint is currently active.

The components of the SensorSetpointReadType have additional subcomponents which are defined in Table 17.

Some devices may control a process value via alternative, mutually exclusive setpoint (e.g. a target value for either pressure or airflow may be specified). The IsActiveSetpoint variable indicates whether the setpoint of an instance of this type is the currently active setpoint.
