ABBAdvant® Controller 450 The 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 noisesuppression purposes. Cabinets with various degrees 

of protection are available, e.g. ventilated, tropical 

and sealed, with or without heat exchangers.
