New Technology for Improved Quality Control and Security of Process Operations
A modern control room will incorporate computer systems for the monitoring and control of the process, ranging from powerful large machines to simple PLC units. Process operation is typically a blend of automatic and manual supervision. The computers carry out startup/shutdown sequencing, a level of automatic control via conventional PID regulation and a level of supervisory control via purpose calculations. Color screen/keyboard facilities provide operators with information to manually oversee plant status and also the capability to interact with the control systems to ensure operation is to specification. Two important factors in an operator’s brief are:
To maintain product quality, at appropriate throughput and with appropriate economy and
To ensure that plant operation is maintained within defined boundaries.
