Confirm that the model supports historical storage, enable it on the tags to record, and configure the database and sampling interval. The documented web History Query selects one or more stored tags and a time range, then downloads CSV data or a PNG chart. Alarm-query results can also be downloaded as CSV.
Local retention depends on storage hardware, database type, tag count and logging interval. Do not assume one retention period applies to every model. For long-term centralized storage, check the external-database functions supported by the target model. Start with a few tags to verify timestamps, query ranges, export content and actual logging interval.
