The system's architecture, DeviceNet, is an open-network, device-level feedbus that links the various system components and allows them to "talk" to one another. Designed to bring the maximum amount of information back to the system's Master Station for monitoring and control, this architecture maintains optimal operation of the actual hardware.
The Master Station combines an Operator Interface and Control Panel through an Allen-Bradley SLC 5/04, a DeviceNet scanner, minimal local I/O, and an Allen-Bradley PanelView touchscreen display.
Power distribution, servo motor control for the meter, interface with robotics, crossover control for the material supply pumps and temperature conditioning, pressure or proximity sensors, customer interlocks, and other miscellaneous field I/O are distributed as separate nodes through the system.
