Abstract: The automatic monitor and control of cement chamotte calcination manufactured
process is realized by using ControlLogix 5550 PLC and the concerned configurational
software,which are made by Allen-Brdley Company.The system adopts the ways
2-stage DCS control.The inferior computer accomplishes the collection and dispose of
data,and accepts the computer’s instructions so that it can send signals to accomplishes
all kinds of processes control and other tasks,while the epistatic computer is
responsible for the task to monitor,handle,control and adjust PID parametor,then data
disposal and perform the functions of printing.The system is reliable and stable in
functions.
