800xA History

Information is a key asset of all businesses

Reduced time to decision and action is critical for improving quality and productivity. Secure, reliable and scalable data management is a key cornerstone of any Information Management solution.  The 800xA History secure data and seamlessly present historical information in the proper context to operations, maintenance and management. The result is reduced time to decision and actions that are critical to the productivity of the plant.

800xA History helps to collect information from the sensor to the executive's desktop. It is designed to be a high-performance process historian for the management of real-time data and events. It reliably gathers and serve large volumes of data. It delivers information to the right people at the right time and brings system and people together.

The 800xA History provides access to history data through standard interface like OPC and ODBC and insulates the automation system from the applications accessing the process data. 

Benefits

Secure Historic Data Storage and Access: Data availability is increased by fault tolerant and distributed configurations. Data integrity is protected by user access restrictions and offline storage.

Flexible Report Generation and Distribution: A wide variety of reporting requirements are supported in familiar formats. Versatile scheduling options provide automatic triggers for key actions.

Sophisticated Data Transformation: User defined data structures and calculations provide powerful, reusable algorithms in addition to external application data support.

Accessible Archive Services: Electronic records access is secure and reliable using approved offline management archiving functions.

Integrated Administration and Configuration: Inherent system configuration and administration provides a single information repository and single point change management eliminating duplicate engineering effort.

Intuitive Presentation: Desktop displays give managers concise information in familiar office formats. Operator displays provide historical information in the control system environment.

800xA History features

History server
History embedded data collector

History Server is responsible for storing raw data and aggregated data from the control system. It stores the raw data in Real time database and aggregates the same data. History also stores events and manages system configuration. It provides open interfaces for external applications.

History Servers are logically linked together at a site, and across an enterprise, to provide a common historical data environment. This allows seamless data retrieval from all points within the system. Moreover, History Management functionality can be applied to a single ABB control system, or across multiple control systems from multiple vendors.

Information from all applications in the extended automation system is readily available in a variety of straightforward views and reports, which can be customized by operators, engineers, maintenance personnel and managers to utilize precisely the information they need to run their business better. Tight integration also means that data – both real-time and historical – can be accessed and retrieved from anywhere in the system regardless of where it originated or is stored. This makes it possible for each user to document activities and review past events specific to their responsibilities. They can view, analyze and use the information they require precisely where and when it is needed, so that the time it takes to make important decisions can be reduced.

History storage

History Embedded Data Collector is a node in History architecture, which is responsible for data buffering of raw OPC data. History Embedded Data Collector stores the raw data in the real time database, which is a part of Data Collector Node.

The raw data is stored in the real time database for seven days in the Data Collector Node, which is sent to History server.

The following are the features of History Embedded Data Collector:

• It can be configured to execute in pairs.

• It provides interfaces for data access.

• It is very simple to install and has a fixed data model for storage based on purpose.

• It can be embedded in other applications.

• The engineering is driven from History server in the History architecture.
