The last decade has seen many new measurement and control techniques developed.This has been principally due to the development cent dyyni of low cost electronic circuits and, more recently, the microprocessor.As a result of this rapid development the instrument and process control engineer is faced with the arduous task of interfacing new and old equipment with differing transmission and communication requirements.

The situation is further complicated by the numerous transmission and communication techniques that are available and the usual dogma of finding differing communication interfaces at either end of the connecting cable.This paper provides an insight to the array of transmission and communication techniques currently in use and looks at new techniques which are verona wig being developed.The application of the transmission and communication techniques to process control systems is a subject which is now under careful scrutiny as the establishment of an effective transmission and communication configuration can result in an appreciable cost advantage and increased transmission efficiency.

A number of these configurations (networks) are discussed.
