Overview
The PCS 7 Asset Management supplements SIMATIC PCS 7 by
a valuable instrument for minimization of the total cost of owner-
ship of a plant.

Asset management for plant engineering is understood to be the
administration and management of the plant equipment, partic-
ularly the I&C equipment, as well as all activities and measures
which serve to retain or increase the value of a plant. These pri-
marily include:
• Corrective maintenance
• Corrective maintenance
Reaction to existing fault and diagnostics messages
• Preventive maintenance

Function
Maintenance functions and information are frequently only avail-
able in a separate level independent of the production. Parallel
to process control, SIMATIC PCS 7 with the integral asset man-
agement system also provides uniform maintenance information
and functions in the process control system for the system com-
ponents of the plant (assets). Supplementary hardware or soft-
ware tools for asset management functions are therefore super-
fluous.
Whereas the plant operator receives all information relevant to
Whereas the plant operator receives all information relevant to
the process via the operator system and can specifically access
the process, the maintenance engineer checks the hardware of
the automation plant via the maintenance station, and processes
its diagnostics messages and maintenance requests.
When implementing the SIMATIC PCS 7 asset management,
consistent attention was paid to the conformity with international
standards, specifications and recommendations. SIMATIC
PCS 7 asset management takes into account e.g. the NAMUR
requirements (process control standards committee in the
chemical and pharmaceutical industries) defined in the follow-
ing documents for systems for asset management at plant level
and for status messages from field devices:
• NAMUR recommendation NE91 (requirements for systems for
• NAMUR recommendation NE91 (requirements for systems for
asset management at plant level)
• NAMUR recommendation NE 105 (requirements for the inte-
gration of fieldbus devices in engineering tools)
• NAMUR recommendation NE107 (status messages "Device
failure", "Maintenance requirements", "Function check" from
field devices).
In addition, it observes the IEC 61804-2 for describing devices
by means of the Electronic Device Description Language
(EDDL) and specifications made by the PROFIBUS & PROFINET
International (PI) organization, e.g.:
• PROFIBUS Profile Guidelines Identification & Maintenance
• PROFIBUS Profile Guidelines Identification & Maintenance
Functions
• PROFIBUS PA Profile for Process Control Devices

Integration
The SIMATIC PCS 7 Asset Management is integrated seam-
lessly into the SIMATIC PCS 7 process control system as a sec-
tor-independent software package. It consistently uses the hard-
ware and software components of the engineering system and
operator system.
The system interface for maintenance engineers is the mainte-
The system interface for maintenance engineers is the mainte-
nance station based on the engineering system (for details, see
the next Section "Maintenance station").

Configuration
The PCS 7 Asset Management is based on the hardware and
software project of the application which is generated during the
standard configuration with the SIMATIC PCS 7 engineering sys-
tem. Supported by the system, all data relevant to the PCS 7 as-
set management are derived from the project data of the appli-
cation simply by pressing a button, and the diagnostics displays
are also generated.
The procedure is simple, and no additional overhead is required
The procedure is simple, and no additional overhead is required
for the asset management. It can be summarized as follows:
• Generation of the hardware and software project of the appli-
• Generation of the hardware and software project of the appli-
cation
• System-supported generation of the diagnostics displays with
all components present in the project, including the display hi-
erarchy, according to the project’s hardware structure. The
names of the displays, symbols etc. imported from the project
can be changed by users according to personal requirements
or depending on project-specific features. These modifica-
tions are retained during further operations
• Compilation of the configuration data, and downloading to the
operator station and maintenance station with subsequent test
and commissioning phase.
