26.4 Value Status Attribute
|For Standard||PRODML v2.0|
In a Time Series Data object, the value status attribute is used as an indicator of the quality of the value.
IMPORTANT: If the status attribute is absent and the value is not set to NaN, then the data value can be assumed to be good with no restrictions.
The example in Figure 26.4-1 shows several readings, each with a status of frozen, which indicates the sensor has been reading the same value for a specific period of time.
