ABB-Controller 450The 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.
