Plant Device Management
SIMATIC PCS 7 Maintenance Station
■
Overview
The maintenance station is specialized for plant asset manage-
ment (also known as plant-floor asset management), i.e. the
management of company assets that are used as fixed assets
for production. Its tasks include efficient administration and
management of equipment in technological systems, in particu-
lar the I&C equipment, with the objective of maintaining and in-
creasing the value.
The following maintenance strategies are used for this purpose:
•
Corrective maintenance
Response to pending error and diagnostics messages
-
Failures are risked or minimized by redundant configurations
- Maintenance in the form of repair or replacement
•
Preventive maintenance
Preventive diagnostics and maintenance
- Initiation of appropriate maintenance measures before a
fault actually occurs
- Maintenance in the form of time-dependent or status-
dependent maintenance (depending on degree of wear)
•
Predictive maintenance
Predictive diagnostics for timely detection of potential
problems and determination of the remaining service life
Using the maintenance station, the maintenance engineer can
check the hardware of the automation system, evaluate its diag-
nostics messages and information and derive maintenance
measures from them. He or she is thus in a position to plan, con-
trol and document the entire maintenance cycle - starting with
the arrival of a diagnostics message, continuing with the evalu-
ation of detailed diagnostics information and the planning, initi-
ation and tracking of maintenance measures, all the way to their
completion.
SIMATIC PCS 7 Maintenance Station
The SIMATIC PCS 7 Maintenance Station makes additional hard-
ware or software components for plant asset management su-
perfluous. Fully integrated in SIMATIC PCS 7, it supplements the
process control system with a valuable instrument for minimizing
the total cost of ownership over the complete life cycle of the
plant.
Parallel to process control, the SIMATIC PCS 7 Maintenance Sta-
tion provides consistent maintenance information and functions
for the system components of the plant (assets):
•
The plant operator receives all process-relevant information
via the operator system, as well as an overview of the
diagnostics status of the process control system.
•
The maintenance engineer checks the hardware of the
automation system using the SIMATIC PCS 7 Maintenance
Station, and processes its diagnostics messages and mainte-
nance requests.
The SIMATIC PCS 7 Maintenance Station provides maintenance
and service personnel access to:
•
Components of the process control system, e.g. intelligent
field devices and I/O modules, fieldbuses, controllers, network
components and plant buses as well as single stations,
servers and clients
•
Assets that do not directly belong to the process control
system, such as pumps, motors, centrifuges, heat
exchangers (mechanical assets) or control loops. They are
represented by proxy objects in which the diagnostics rules
are stored.
It is therefore no longer the case that maintenance functions and
information are only available in a separate level independent of
the production process.
Plant operators and service personnel are thus able to con-
stantly act the following, for example:
•
Service requests
•
Service approvals
•
Placing an asset in "In Service" status
•
Information regarding a completed service measure
