The DNP3 adapter creates types at startup. One stream is created for each selected DNP point represented by an item in the data selection configuration.
Each stream contains three properties:
|
Property name |
Data type |
Description |
|---|---|---|
|
Timestamp |
DateTime |
Timestamp of the value update for the DNP point |
|
Value |
Specified in the data selection configuration |
Value of the DNP point |
|
Quality |
Byte |
Data quality of the given DNP3 item update. Quality values are defined in Supported features. |
Note: All streams contain the Quality property except if the DNP3 Point Type is Octet String.
Certain metadata are sent with each stream created. See Metadata for detailed information about metadata for data streams and metadata for health and diagnostics streams.
