ABB HR Series Control and I/O
ABB Ability™ Symphony® Plus is the new generation of ABB’s highly acclaimed
Symphony family of distributed control systems – the world’s most widely
used DCS in power generation and water management applications. In all,
there are more than 7,000 Symphony DCS installations in operation all over
the world, more than 5,000 of which are in power and water applications
No other automation platform has such a long
field record and large global installed base as
ABB’s Symphony Plus family. For more than 35
years, the system has progressed through several
evolutionary steps. From Network 90 in 1980,
through INFI 90TM, INFI 90TM Open, and Symphony,
to Symphony Plus, the system progression has
followed ABB’s long-held policy of ‘Evolution
without obsolescence,’ ensuring that each new
generation enhances its predecessor all the while
maintaining full compatibility with them.
Symphony Plus includes a comprehensive suite
of standards-based control and I/O hardware
and software that meets your requirements
for total plant control. The suite's HR Series
(Harmony Rack) meets the past, present and
future needs of its users by protecting their
previous control investments while delivering
higher performance, reliability, and capacity.
HR Series control-based systems feature scalable,
high-performance controllers, a comprehensive
set of I/O options, fast, secure and redundant
communications, an efficient easy-to-use
engineering tool, and a state-of-the-art HMI
workplace. Newest additions to the HR Series
portfolio include an environmentally hardened
DIN-rail mounted native remote I/O option and
integration of intelligent electrical and field
devices via PROFIBUS, HART and Modbus TCP
communication protocols.
In summary, HR Series control-based solutions
lower system life cycle costs and total cost
of ownership by delivering the value needed
to remain competitive in today’s challenging
business environments: increasing reliability,
minimizing equipment downtime, improving
production yields, reducing maintenance and
support costs, reusing physical and intellectual
control and I/O investments, and adding new
products and features with ease.
