Plant Device Management
SIMATIC PCS 7 Maintenance Station
The signaling system, user interface, picture hierarchy and
operator prompting are based on the HMI philosophy of the
operator system. The diagnostics data of all assets are dis-
played on uniform faceplates whose contents depend on the
intelligence of the respective component. This means that work-
ing with the SIMATIC PCS 7 Maintenance Station is simple and
intuitive – a time-consuming training period is not required.
The SIMATIC PCS 7 Maintenance Station uses the optional prod-
uct package SIMATIC PDM PCS 7 Server for parameter assign-
ment and diagnostics of the devices integrated via an Electronic
Device Description (EDD). The optional product component
SIMATIC PDM-FF is required for plants with FOUNDATION Field-
bus H1.
For editing the devices, the user receives the functional rights
corresponding to their role following identification. User man-
agement and access control for the SIMATIC PCS 7 Main-
tenance Station is handled by SIMATIC Logon integrated in
SIMATIC PCS 7.
SIMATIC PDM supplies comprehensive device information for
display and further processing on the maintenance station and
can be called from any SIMATIC PCS 7 Maintenance Station
Client (MS Client). The display of diagnostics displays struc-
tured according to the plant hierarchy with the operating states
of the SIMATIC PCS 7 components is possible both on purely
MS clients and combined MS/OS clients. The faceplates of
these stations can also display the enhanced diagnostics infor-
mation determined by SIMATIC PDM. A device-specific call of
SIMATIC PDM is also possible. However, enhanced online diag-
nostics functions in conjunction with HW Config can only be
called on stations that are both an MS client and engineering
station for SIMATIC PCS 7 at the same time.
Configuration
The SIMATIC PCS 7 Maintenance Station is based on the hard-
ware and software project of the application which is generated
during the standard configuration with the SIMATIC PCS 7 engi-
neering system. With system support, all data relevant to the
plant asset management are derived from the project data of the
application, and the diagnostics screens are also generated,
simply by pressing a button. The procedure is simple, and re-
quires no additional configuration work:
•
Generation of the hardware and software project of the appli-
cation
•
Parameter settings for optional functionalities
•
System-supported generation of the diagnostics screens with
all components present in the project, including the picture
hierarchy based on the project's hardware structure
•
Compilation of the configuration data, and downloading to the
operator station and Maintenance Station with subsequent
test and commissioning phase
The names of imported pictures, icons, etc. can be permanently
changed for further use in the maintenance project.
Conformity to international standards, specifications, and
recommendations
Plant asset management with the SIMATIC PCS 7 Maintenance
Station conforms to international standards, specifications, and
recommendations. It is based on the NAMUR requirements (pro-
cess control standards committee in the chemical and pharma-
ceutical industries) defined for systems for plant asset manage-
ment and for status messages from field devices:
•
NAMUR recommendation NE129 (requirements for systems
for plant asset management)
•
NAMUR recommendation NE 105 (requirements for the
integration of fieldbus devices in engineering tools)
•
NAMUR recommendation NE107 (status messages from field
devices "Device failure", "Maintenance requirements",
"Function check")
In addition, it also observes 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
Functions
•
PROFIBUS PA Profile for Process Control Devices

Function
Diagnostics message of a component in the "Identity" faceplate view
The SIMATIC PCS 7 Maintenance Station provides maintenance
engineers with comprehensive maintenance information on the
system components (assets) of the plant. Starting from the over-
view display, maintenance engineers can navigate to the diag-
nostics displays of the subordinate hardware levels to obtain in-
formation on the diagnostics status of individual plant areas or
components. If a fault is signaled in the overview display, the
"Loop in alarm" function permits rapid switching to the diagnos-
tics faceplate of the associated component.
The scope of information available depends on the individual
possibilities of the asset, and is filtered according to the user's
area of responsibility.
The following information is available, for example:
•
Display of diagnostics status detected by the system
•
Information on the component, such as process tag name,
manufacturer or serial number
•
Display of diagnostics messages of an individual component
•
Visualization of the type and current state of the initiated
maintenance measure
