Maybe a bit off-topic, but if you don't need archiving nor batch event logging - but only trend logging for operators and reports you should not rule out Basic History!
The System Guide does no longer restrict you to 90 days of storage in Basic History.
Its a well known fact that the capacity of Basic History by far exceed 90 days.
Furthermore Basic History can run on existing connectivity servers (i.e. does not require any data collector nor dedicated server nodes), is easily configured for redundancy, has an integrated backup/restore function in 800xA, offers an OPC HDA server interface for custom applications and best of all is shipped free of charge with every 800xA System.
