ABB Advant® Controller 450 proven process controller

ABB Advant® Controller 450 proven process controller

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 redundancy 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.
