Concentrated Control Systems using one large process capacity computer have been used for rationalization and process optimation. Around the year 1980 the introduction of micro-computers with a V LSI made it necessary to review the traditional process control systems. This has led to the development of Distributed Process Control Systems, which is based on the need for a distribution of risk, function and information in a process. The new mode of process control has developed into a hierarchic System, combining optical devices with the communication system, a man-machine interface with a CRT display with advanced function and with intelligent sensors. The paper will present the present status and the prospects of Instrument and Process Control Systems in tobacco manufacture.
