ABB Advant® Controller 450
Advant Controller 450 is a high-end
process controller. Its high processing
capacity and wide-ranging process
and system communication capabilities
make it the ideal choice for demanding
applications, either standing alone
or as part of a ABB Ability™ System
800xA with Advant® Master
Does everything in process control
Advant Controller 450 can do “everything” in process
control, not only perform logic, sequence, positioning
and regulatory control but also manage data and text
generally and produce reports. It can even perform
selftuning adaptive, PID control and fuzzy logic control.
The station is programmed graphically in AMPL,
as are all other controllers in Advant OCS with Master
software. The already rich library of program elements/
function blocks can be augmented with user-developed
blocks created in AMPL.
A full complement of I/O
The range of process I/O modules is complete, covering
general-purpose analog an digital inputs and outputs
at different ratings as well as Pt100, thermocouple
and pulse inputs. Specialized interfaces are provided
for accurate digital positioning, switchgear integration,
variable-speed motor control, telecontrol and
communication with other makes of programmable
controllers. The overall I/O capacity is as high as
5,700 I/O points.
Both central and distributed I/O are available
Central I/O (S100 I/O) modules are plugged into I/O
racks installed in close proximity to the CPU rack/
cabinet. Distributed I/O (S800 I/O) stations can be
installed up to 13,3 km (8,2 miles) away, communicating
over Advant Fieldbus 100, a high-speed serial
communication bus.

The controller that stays in touch
Advant Controller 450 supports a wide range of
communication protocols, making it easy to design
the optimal control system architecture for every
application. These protocols include:
• MasterBus 300/300E for communication with other
member stations of Advant OCS at the Control
Network level.
• GCOM for communication with AdvaSoft for Windows
and external computers. The easy, powerful, for
external computers to access process data in Advant
OCS. Both ways.
• Advant Fieldbus 100 for communication with distributed I/O stations, programmable controllers and
motor drives.
• RCOM/RCOM+ for long-distance communication
with remote terminals, using dedicated or dial-up
telecommunication lines.
• RS232 for communication with external computers
at the process signal/device level by ABB’s EXCOM
protocol and for local printout of data, reports,
event messages and alarms.
• MVI (Multi-Vendor Interface) for communication
with other makes of control systems over MODBUS I,
Siemens 3964R or Allen-Bradley’s DF1.
• Profibus DP for communication with other makes
of controllers and with stand-alone I/O systems
made for this popular communication protocol.
• Telecontrol communication with dispatch centers,
power stations and remote terminals.
• SPA bus communication with relay protection units.

Redundancy at all levels
To achieve the highest possible availability, Advant
Controller 450 can be equipped with backup redun dancy for MasterBus 300/300E, Advant Fieldbus
100, power supplies, voltage regulators, backup
batteries, battery chargers, central units (CPUs and
memories) and I/O boards for regulatory control.
The central unit redundancy is of a patented hot standby
type, offering bumpless changeover in less than 25 ms.
Enclosures
Advant Controller 450, equipped with local S100 I/O,
consists of one CPU rack and up to five I/O racks.
Optical bus extension makes it possible to distribute
the S100 I/O up to 500 m (1,640 ft.) away, thus
reducing the amount of field cabling required.
The I/O racks are designed for installation in cabinets
with a swing-out frames, permitting access to both
the front and the rear of racks for ease of installation
and maintenance. The external connections are routed
through connection units normally fitted inside, at
the back of the cabinets for marshalling and noise suppression purposes. Cabinets with various degrees
of protection are available, e.g. ventilated, tropical
and sealed, with or without heat exchangers.
