ABB PM511V16 3BSE011181R1 Central Processing Unit
Making real-time business decisions toprevent or limit process upsets requires a
consistent infrastructure for data, operations,
configuration, and maintenance across the
entire enterprise. The foundation of this
consistent infrastructure is ABB’s Aspect
Object™ technology provided by the Aspect
Integrator Platform (AIP) component. Every
Two Decades of Enhancements
Industrial IT software product is based upon
the AIP component. Symphony Harmony
fully participates in an integrated Industrial
IT environment by leveraging the full power
of the Aspect Object technology by employ ing an open,
enterprisewide architecture that
supports a seamless communications fabric
to every level of control – from field I/O to
plantwide and multi-plant systems. SYMPHONY
Harmony essential security and proven
availability at the control level are integrated
with enterprise network strategies for total
enterprise communication.
The scalable SYMPHONY Harmony architec ture allows for easy integration of ABB
Industrial IT components, such as Operate
IT, Produce IT, Inform IT, and Optimize IT.
In addition, non-traditional DCS functional
areas, such as field device management and
PLC controls, simply “plug-and-produce” in
the SYMPHONY Harmony architecture via
other ABB Industrial IT components, such
as Engineer IT and Control IT.

ABB’s Industrial IT with SYMPHONY solutions
reach beyond the traditional boundaries of
distributed control systems to support the
platform, application and professional
service needs of total enterprise manage ment and control.
SYMPHONY’s multi-tiered span of control
provides a secure foundation with robust,
but flexible, base level regulatory and
sequence control. Solutions continue
through the full range of higher level man agement and advanced control functions to
include: production management, mainte nance management, simulation, historian,
and network management. The integration
of these powerful features is achieved through
SYMPHONY’s integrated “plant-centric”
architecture. Embodied in the principles of
open, real-time networking, the SYMPHONY
architecture provides a scalable communica tions fabric that spans and integrates loop,
unit, area, plant, and interplant controls
