Function
Process Historian
The Process Historian can archive process values, messages,
and batch data from the SIMATIC PCS 7 process control system.
It is configured in a SIMATIC PCS 7 project similar to other sta-
tions of the SIMATIC PCS 7 process control system (e.g.
OS Server, Batch Server, Route Control Server, OpenPCS 7
Server or all clients).
The process values and alarms managed in the database of the
Process Historian on the OS clients and OS single stations can
be visualized in a clear and user-friendly manner. Data selection
is supported by integrated filter functions. Messages and pro-
cess values can be shown in table form, and process values
also in graphic form. Tables of process values can be exported
in CSV format for further processing in other Windows applica-
tions, e.g. Microsoft Excel.
Any application can access the archived process values and
messages in the Process Historian via OPC UA.
The data managed by Process Historian can be transferred to
external storage media (Backup/Restore). This requires addi-
tional hardware and software suitable for the operating system of
the Process Historian, for example NAS.
The Process Historian also supports backup and restoring of the
complete database – both manually and automatically.

•
Real-time archiving of process values and messages from
SIMATIC PCS 7 Operator Systems (OS single stations and
OS servers)
•
Real-time archiving for the batch data of SIMATIC BATCH
•
Conversion of runtime segments in archive segments:
- Loss-free data compression

and release of unused storage space
•
Support of multiple SIMATIC PCS 7 projects
•
Scaling relative to the basic hardware employed in terms of
performance and quantity structure
•
Export of all data as well as cataloging onto external storage
media
•
Reading the swapped-out data and cataloging from external
storage media
•
Data visualization on the OS clients/OS single stations:
- Configuration of views (picture windows and masks)
including the selection criteria for displaying the data
- Visualizing of messages in table form dependent on filter
functions
- Displaying of process values in table or graphic form
dependent on filter functions
- Visualization of a batch overview (selecting the detailed log
of a batch from the batch overview is possible)
