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.

Attribute Description |
|
Signal |
Value of the signal. This includes min/max ranges, unit and other meta information. The optional setpoint should be implemented only for SensorSetpointReadType and SensorSetpointWriteType types. |
|
2:Identification |
Data to identify the sensor (OPC 40001-1). |
|
SignalForm |
Specifies whether the sensor is an analog or a digital sensor. |
