Perhaps the most essential element in any mine-optimization effort is a modern distributed control system (DCS). A modern DCS connects all aspects of a mining operation – from the extraction site, to material transportation, and finally down to processing and refining. This mine-wide control approach does away with many of the hassles ...

The three most common controller modes are Automatic, Manual, and Cascade. In Automatic mode, the controller receives the setpoint value (SP) and the measured value of the process variable (PV), and calculates and sends an output signal (OP) to the actuator. In Manual mode, the controller is overridden, allowing operating personnel to send the ...
