The different parameters used in this example query string are:
- TAG: specifies the name of the tag to retrieve data for.
- START: specifies the start date and time of the data to be retrieved.
- END: specifies the end date and time of the data to be retrieved.
- INTERVAL: specifies the sampling interval for the data.
- MODE: specifies the calculation mode to be used for the retrieved data.
The query string syntax and available parameters may vary depending on the version of WinCC you are using. Please refer to the WinCC documentation for more information on how to construct archive tag query strings.
- Query string syntax: The query string syntax may vary depending on the version of WinCC you are using. In general, the syntax follows the format “KEYWORD:VALUE”, where the keyword specifies the type of data to retrieve and the value specifies the search criteria. Multiple keywords can be used in a single query string, separated by semicolons.
- Query string keywords: WinCC supports a variety of keywords that can be used to construct archive tag query strings. Some commonly used keywords include TAG (to specify the tag name), START and END (to specify the time range of the data), INTERVAL (to specify the sampling interval), and MODE (to specify the calculation mode). Other keywords may be used to filter the data by quality, event type, or other criteria.
- Query string values: The values specified in the query string depend on the keyword being used. For example, the TAG keyword requires a string value that corresponds to the name of the tag being queried. The START and END keywords require date/time values that define the time range of the data being queried. The INTERVAL keyword requires a value that specifies the time interval between data samples, such as “1h” for hourly data or “5m” for data sampled every 5 minutes.
- Query string results: Once a query string is executed, WinCC returns the requested data in a format that depends on the query string parameters. For example, a query string that retrieves data for a single tag over a specified time range may return a table of values with one row per data sample. The table may include additional columns that provide information about the quality of the data, the event type that generated the data, or other metadata.
