SIMATIC PCS 7 process control system

Component/device spectrum
Devices/components of the SIMATIC PCS 7 process control system
and of the connected process I/O belong to the described
maintenance cycle. These include:
■ PC basic devices (server, client, single station)
■ Automation systems (controller)
■ Network components for plant bus, terminal bus and fieldbus
■ Distributed I/O (remote I/Os)
■ Field devices (sensors/actuators).
Integration in SIMATIC PCS 7
The PCS 7 asset management is integrated seamlessly into the
SIMATIC PCS 7 process control system as a sector-independent
software package. It consistently uses the hardware and
software components of the engineering system and operator
system.
The system interface for maintenance engineers is the maintenance
station based on the engineering system. Via this,
they have access to the complete hardware structure of the
process control system, and can process diagnostics messages
and maintenance requests.
Configuring
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 engineering system. All
data relevant to the PCS 7 asset management are derived
from the project data simply by pressing a button, and the
diagnostics displays are also generated. The procedure is simple,
and no additional overhead is required for the asset management:
■ Generation of the hardware and software project.
■ System-supported generation of the diagnostics displays
with all components present in the project, including the
display hierarchy 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 projectspecific
features. These modifications 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.
Maintenance station
Architecture
The maintenance station for the PCS 7 asset management
provides comprehensive maintenance information for the
system components of the plant (assets).
Depending on the project-specific SIMATIC PCS 7 architecture,
the maintenance station can be based on a SIMATIC PCS 7
BOX, PCS 7 single station or client/server combination. It uses
the hardware and software components of the engineering
system and operator system.
As a result of the close interlacing, ES, OS and asset management
functions execute on common hardware. Such a multifunctional
station cannot only be used for asset management,
but also for system engineering or HMI.
The message system, user desktop, display hierarchy and operator
prompting are oriented according to the HMI philosophy
of the operator system. The diagnostics data of all assets
are displayed on uniform faceplates whose contents depend
on the intelligence of the respective component. This means
that working with the maintenance station is simple and intuitive
– complex familiarization is not required.
The diagnostics displays structured according to the plant hierarchy
with the operating states of all SIMATIC PCS 7 components
can be displayed on the maintenance station and also
on an OS client. However, enhanced online diagnostics functions
in conjunction with HW Config or SIMATIC PDM can only
be called from the maintenance station.
The SIMATIC Logon handles user management and access
control for the maintenance station.
