When you enable this feature, you can choose to store an unlimited, or a maximum number of records in the storage file for the database. You can define separate storage options for Alarm Logging and Point Logging.
If you choose to store unlimited records, the Database Logger continues to save data records until it runs out of disk space. The following message is then logged in the Status Log:
Unable to write to store and forward file, <filename>
and the Database Logger continues to try to save additional records.
If you choose to store a maximum number of records, the Database Logger saves the configured number of records then stops, and the following message is logged to the Status Log.
Number of stored records exceeded maximum <max_no>
The records are stored in one or more files in a storage directory. The number of files depends on the maximum number of records you select and the maximum number of records per file.
Store and forward.
