The TurboWatch system also serves as a data repository that collects and analyzes data from a variety of sources.  Leveraging latest Microsoft Windows® technology the TurboWatch Historian is a robust multithreaded service that stores data using Microsoft SQL as the backend database system. The System stores both steady state and transient data, the amount of history stored is user configurable and is limited only by available disk space.

Historian_icon_1Steady State Data

While real-time data is monitored every second, steady state data is stored at user defined periodic intervals.  Multiple steady state data tables can be defined with different storage intervals.  For example a short term table can be configured to store data every 10 minutes for 1 year while a long term table can be configured to store data every hour for 5 years.  The amount of data stored in each table is only limited by database size and disk space.

Historian_icon_3Data Validation & Alarming

TurboWatch allows setting of five different alarm thresholds for every measured or computed point. In addition, rate of change alarms and alarm deadbands can also be set for individual points.  Every point can also be assigned an alarm severity level based on its criticality.

Historian_icon_2Transient Data

The system stores data at an accelerated rate of once per second during machine transient events such as startups, trips and shutdowns. Transient captures can be triggered automatically or manually by a user.  Multiple transient data sets can be stored for each machine.  This helps in making before and after comparisons of transient data in case of machine overhaul or any other maintenance event.

Historian_icon_4Triggered Logging

Soft triggers can be setup that can be used to trigger steady state or transient data logging or to suppress alarm logging during transient events.  These triggers are based on configured analogue thresholds or on measured or computed digital points or a logical combination of the two.
