Guarantee data integrity and eliminate the risk of regulatory non-compliance with automated gap detection and backfill.

Complete data continuity. Always.

Dynamic Application Structure

Add unlimited users, plants, PLCs and Historian Servers to accommodate applications of any size. The intuitive interface makes for easy setup and configuration.


Centralized with Flexible Export
