VTScada Historian supports applications that log hundreds of thousands of I/O. Advanced synchronization allows every redundant SCADA server to be an up-to-the-second backup of all process histories. The historian is part of every application and allows any server to assume polling and logging as needed according to a distributed server list. This reduces computer hardware (no dedicated I/O server) and increases levels of data redundancy. The integrated design means that new servers can be added in seconds. Each server can host multiple historians, allowing for flexible data backup scenarios. Users can log redundantly to third-party historians if needed (licensed separately).
