Advant® 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.

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.

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.
