Coal Processing - an overview | ScienceDirect Topics

1982-8-9 · A state-of-the-art coal processing facility typically uses a programmable logic controller (PLC) as the heart of the plant control system. The PLC is a computer based controller that acquires data (input) representing the status of all the units and control loops in the plant, makes decisions based on the data input and programmed instructions, and sends data (output) to the plant units reflecting the decisions.
