Raw Data API

The Raw Data API queries raw data, such as a number of samples or the time range for a list of tags. If the count is not zero, then the API service returns the number of raw samples taken beginning from the start time. If the count is zero, then the service returns the raw samples taken between the start time and the end time.

Query Parameters

Parameter	Description	Required?	Values
TagNames	Queries the specified tag names.	Yes	String
Start	Start time of the query, in ISO data format (such as YYYY-MM-DDTHH:mm:ss.SSSZ).	Yes	DateTime
End	End time of the query, in ISO data format (such as YYYY-MM-DDTHH:mm:ss.SSSZ).	Yes	DateTime
Direction	Specifies the direction (Forward or Backward from the starting time) of data sampling from the archive. The default value is Forward (0).	Yes	Integer, with a value such as 0.

Response Parameters

Parameter	Data Type	Required?	Description
ErrorCode	Integer	Yes	For example, 0.
ErrorMessage	String	Yes	For example, NULL.
Data	String	Yes	The object container for the following parameters: DataType DoubleFloat, which stores decimal values up to 15 places. ErrorCode Value is 0, which means the operation was successful. TagName Example: TagName1. Samples Provides TimeStamp, Value and Quality for each sample. For example, TimeStamp = 2013-10-02T11:30:00.111Z, Value = 34.26155, and Quality = 3.
