The Basic History service is "limited"* to 90 days of storage in System 800 HMI (CHMI's "Big brother").
*) Limited: its possible to create logs sampling every second and stretching for over a decade, but Basic History has not been fully tested and marketed with such high capacity in favor for other historians.
