Reference: Status codes
This page lists the valid quality status codes for time series data points.
Main status codes
All status codes fall into one of the main categories: Good, Uncertain, or Bad. If status code is missing, it is assumed to be Good (with code = 0).
The API uses decimal numbers to represent status codes, but we have included the hexadecimal representation for reference.
| Symbolic representation | Code (decimal) | Code (hexadecimal) |
|---|---|---|
| Good | 0 | 0x00000000 |
| Uncertain | 1073741824 | 0x40000000 |
| Bad | 2147483648 | 0x80000000 |
Good
Good status codes are the default, and indicate that the data point is valid. If status code is missing, it is assumed to be Good with code = 0.
Bad
Bad status codes are by default omitted from the responses, and indicate that the value cannot be trusted.
Uncertain
Uncertain status codes may be treated as Bad (default) or Good, depending on the user.
Status code structure
A status code consists of a 32-bit unsigned integer code, and a string symbolic representation.
A permitted status code consists of a category and a set of modifier flags or info flags. Use the category as is, or combine it with the modifier flags to get the full status code.
To obtain the full numeric code, you add (or bitwise OR) the values for the category and the modifier flags. To obtain the full symbolic representation, you concatenate the representations for the category and the modifier flags.
The code fields can be added together, while the representations can be concatenated, starting with the category and then the modifiers in order.
For instance is "BadBrowseNameInvalid, StructureChanged, Low" = 2153775104 + 32768 + (1024) + 256 = 2153809152.
The 1024 is added when info flags are used. Here we have set Limit to Low.
