Process Historian and Information Server

Overview of Historian

Historians are today transitioning from their traditional role as plant record-keepers, to tools that have a positive impact on plant operations in real time. With increased data throughput, higher data resolutions, and increased connectivity users can access and leverage huge volumes of plant data today in near real time. With this enhanced functionality, historians have also become a foundation for plant asset management activities.

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 real time – without any additional engineering effort.

Process Historian is scalable 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.

Process Historian and Information Server seamlessly integrated with Simatic PCS 7 Distributed Control System

The Process Historian is used for long-term archiving of the following data from the SIMATIC PCS 7 process control system:

  • OS archive data (process values and messages)

  • Batch data

The process values and messages exported from the OS archives, as well as the batch data from SIMATIC BATCH are managed by the Process Historian in a central database.
