ABB YPQ101E YT,204,001-FS logic card
The Harmony product series consists of
a family of process controllers, communica tion couplers and I/O interfaces. Thirty-two
bit processing, coupled with modular
scalability, make the Harmony family a
powerful and versatile performer.
Harmony Controllers feature an extensive
library of over 240 pre-defined advanced
control algorithms and user-definable func tions. These functions provide the power to
easily design complex control strategies to fit
any control application, including continu ous, sequential, batch, and advanced control.
In addition to standard “function code”
implementation, Harmony Controllers sup port batch language, “C” programming and
even multi-variable control. Available in both
rack and block packaging, the multifaceted
Harmony Controllers communicate simulta neously with numerous field communication
protocols.
To ensure that the SYMPHONY system can
be efficiently configured and maintained,
ABB has designed a comprehensive suite
of Composer Series tools. The Composer
tools provide a visual environment for easy
configuration of control system strategies,
global configuration databases and HSI
graphics, and manage system libraries
of reusable software components.
The working environment of Composer
for Harmony simplifies the configuration
and maintenance of SYMPHONY systems
by providing a standard Microsoft®
Windows environment, which enables
the user to easily explore the current
system configuration and configure new
elements. The use of a common system,
or project-wide database, eliminates the
duplication of data entry and automates
the configuration of many interrelated tasks.
Composer also provides complete system
documentation of the “as installed” and
“commissioned” systems.

The Composer Series tools provide two
key features for system configuration. By
utilizing a multiuser client/server architecture,
they allow configuration information to be
accessed, created and modified simultaneously
by different users. Composer’s integrated
explorer presents a single, unified view of
the SYMPHONY system architecture, and
allows the appropriate tool for each system
element to be invoked directly from that
element.
Consistent with ABB’s commitment to
Evolution through Enhancement, the
Composer Series was designed to integrate
with ABB’s Industrial IT products, while
maintaining compatibility with SYMPHONY
and INFI 90 OPEN systems. Planned integra tion with other components of ABB’s
Engineer IT suite will allow Composer tools
to further enhance design and maintenance
efficiencies throughout the enterprise.
