SIMATIC PCS 7 process control system

Device tag
Symbol display of a component
Visualization of maintenance information
The hierarchical structuring of information and the uniform
symbols support the overview, facilitate orientation, and permit
the maintenance engineer to rapidly access detailed information
starting from the plant overview.
The symbol set defined for the PCS 7 asset management contains
symbols which identify the diagnostics status of the devices/components,
the relevance of the maintenance request,
and the status of the maintenance measure.
Group displays in the plant overview visualize the diagnostics
status of the subordinate structures/components according to
a type of traffic light with red, yellow or green.
Diagnostics displays represent the status of components and
subordinate devices/components through standardized symbols.
These contain the following elements:
■ Bitmap of component
■ Tag identification of component
■ Maintenance status display
■ Group display for diagnostics status of subordinate components
Clicking an element in the symbol display either opens the
subordinate hierarchy level or a component faceplate. The
component faceplate offers various views of the associated
component with further device-specific information, e.g. an
identification, message or maintenance view.
Faceplate for maintenance view
highlights
■ Instrument for minimization of the total cost of ownership
for the complete lifecycle of the plant
■ Diagnostics and maintenance management of the
SIMATIC PCS 7 plant for
– PC basic devices,
– bus components (Ethernet/PROFIBUS),
– automation systems and
– distributed I/O (I/O modules, intelligent field
devices ...)
■ Homogenous integration of maintenance functionality
in SIMATIC PCS 7 – no additional engineering overhead
■ Consistent utilization of architecture and basic performances
of SIMATIC PCS 7
■ Maintenance station as system interface for maintenance
engineer, based on:
– SIMATIC PCS 7 BOX, PCS 7 single station or client/server
combination and
– ES/OS software
■ Same look & feel as with process control on the operator
system
■ Optimized workflow from diagnostics up to termination
of maintenance measure
■ Uniform display of diagnostics and maintenance status
throughout the plant
■ Consideration of international standards and directives:
– NE91 (plant-level asset management)
– NE107 (status messages from field devices)
– NE 105 (integration of fieldbus devices)
– EDD according to IEC 61804-2 (self-diagnostics of
devices).
