Area of application

The SIMATIC PCS 7 Process Historian provides you with high-performance long-term archiving that incorporates itself perfectly into the control system. After all, process data, tags, alarms and batch data from SIMATIC BATCH can be centrally archived in realtime – without any additional engineering effort.

Process Historian is scaleable at will, i.e. data of OS single stations and of OS servers from a PCS 7 project or multi-projects can be detected and saved. No restriction is placed on the number of single stations, servers or server pairs that can be archived. Via a web interface, the information server makes available the archived data as shift, daily, weekly or monthly logs.

Benefits

  • Realtime archiving of process values, messages and SIMATIC BATCH data

  • Non-complex reporting based on the Microsoft Reporting Services

  • Meaningful consolidation and aggregation of data into valuable information

  • Target group-specific output  – periodically and requirement/event-oriented

  • Generation of either classic or dynamic reports e.g.
    - Downtime reports and alarm summaries for maintenance purposes
    - Material deployment reports
    - Consumption data and energy balances
    - Efficiency reports of the different production lines

  • Data can be out-sourced onto customary external storage media and re-inputted

Design and functions

Enlarge

The relational Microsoft® SQL Server 2008 R2 database management system is a reliable and protected database platform for Process Historian. The data storage is not generally compressed. Users can directly access the stored information via the SQL database. Moreover, an open system is involved, i.e. data can be read and written via standard database interfaces such as ODBC, OLE DB and ADO.NET.

The information server provides the data from the SQL database with the aid of the Internet Information Service. As such, process values, messages and batch data can be combined, evaluated or diagrammatically shown. Based on the Microsoft Reporting Services, IS web-based Thin Clients enable historical data to be accessed. Microsoft Word and Excel Add-ins provide additional scope for accessing Process Historian's data stock.
