Process Data Archiving and Reporting
Process Historian and Information Server
■
Overview
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.
They can be visualized on OS clients or OS single stations either
directly or with the support of the information server.
■
Design
Individual consultation on project-specific hardware configura-
tions is recommended. The
PH-HW Advisor
tool is provided to
determine the suitable hardware for the Process Historian:
If high online availability is required, a redundant Process
Historian can be configured with a server pair.
The Information Server can be installed and operated on the
Process Historian hardware or on separate hardware. When the
Process Historian is configured redundantly, separation of the
Information Server is mandatory.
Process Historian and Information Server run with the Windows
Server 2012 R2 Standard 64-bit operating system, the Informa-
tion Server can also run on separate hardware with Windows 7
Ultimate 64-bit or Windows 10 Enterprise 2015 LTSB 64-bit.
The Process Historian and Information Server do not need a con-
nection to the plant bus. They can be connected to the OS and
batch servers of the SIMATIC PCS 7 system via terminal bus,
e.g. via the integrated network connection (Ethernet RJ45 port
onboard) of the server.
Configuration of the Process Historian
The licenses contained in the SIMATIC PCS 7 Process Historian
Basic Package, SIMATIC PCS 7 Process Historian Server Red-
undancy or SIMATIC PCS 7 Process Historian and Information
Server Basic Package are required for configuration of the
Process Historian as the long-term archive of a SIMATIC PCS 7
system. These licenses must always be stored on the Process
Historian server. The SIMATIC PCS 7 Process Historian Archive
BATCH software product for archiving batch data from
SIMATIC BATCH can be ordered optionally.
Configuration of applicative couplings with the Process Historian
Reading of Process Historian data via OPC UA
As an OPC UA client, any applications can read the process
values and messages archived in the database of the Process
Historian. A SIMATIC PCS 7 Process Historian OPC UA Server is
required for this on the Process Historian (software from SIMATIC
PCS 7 Software Media Package plus single license for one
installation).
