7.1 SensorMonitoringType ObjectType Definition

Figure 14 – SensorMonitoringType Inheritance

The SensorMonitoringType represents a process value whose value is determined by a measuring device. It is formally defined in Table 12. The measuring device can be identified via the MachineryComponentIdentificationType from OPC 40001-1.

The process value and all associated metadata such as unit and value ranges are inherited from the ProcessValueType. The optional setpoint of the ProcessValueType must not be used in instances of this type. If a setpoint is needed, the subtypes SensorSetpointReadType and SensorSetpointWrite should be used.

Optionally it can be specified whether the measuring signal is provided in analog or digital form.
