Show TECHNOLOGICAL INNOVATIONS The process control must turn out instruments able to monitor specific data on flow pressure temperature liquid level and humidity during operations But the scale large-scale computers were both too loo expensive and too cumbersome to suit the requirement With Wilh the advent of the less expensive and more sophisticated equipment designed for specific functions the process control companies have hav been able to e costs w 90 f achieve considerably greater flexibility in adopting process changes and even interface with a central computer Not only can the minicomputer puter systems operate alone but when necessary these specific task controls can be hooked up to the central computer as ns part of a distributed computer control network Thus a more economic use of the expensive scale large-scale central computer is achieved Moreover l the network of of- hundreds of small processors and or computers along with the standard manual controls make for continuous process control with interruption held to toa toa toa a minimum |
