Archiving is carried out by the Historian module - Aspad, which efficiently collects data of analog and binary signals. The designer has opportunity to choose the data archiving method: archiving in proprietary format files, guaranteeing data compression on the fly and deleting excess data, or in the MS SQL database

Data is logged using UTC (Universal Time Coordination), leaving no room for ambiguity regardless of winter or summer time, and data from distributed systems in various time zones will be seen in each time zone stamped with the time specific for the individual zone. 

The archived data are made available in the form of raw data or the aggregates to other modules of the Asix platform and third parties software.
