HART's Pot Control System is a Fully Distributed Process Control System designed around Intelís Atom Processor. There remains a dedicated controller for each reduction cell and is capable of independently handle the pot in case of any kind of network trouble. The heart of the system is a Host Computer (HC) which can range from a single PC to a number of PCs on a network. The Controller named as Advanced Pot Controller (APC), is designed for the purpose of automatically controlling reduction cell in Aluminum Smelter Plants. Each APC consists of embedded controller with 256 MB of RAM expandable to 2GB, 512 MB Flash expandable to 64GB, Analog to Digital conversion, digital input/output capability, communication sub-system, SATA and USB interface, front panel with display devices push button switches and membrane keypad. APC software provides anode movement control and Aluminum feed control based on a predetermined strategy for each reduction cell. It also maintains history information like cell operating parameters, various events and exceptions for each cell. When connected to the HC the system provides for data acquisition and report generation facilities. APC Software is highly parameterized, enabling the end user to fine tune/adjust control algorithm from the HC on individual pot or group of pots.
