Description

This paper evaluates the communication network which provides the interface between field devices and the Distributed Control System. The evolution of technologies is evaluated using the principle of S-curves in order to identify the factors which resulted in the switch new technologies. Technology Space Maps are used to audit the position of the Control Engineering Group of Sasol with regard to these communication technologies. The methodology of the Technology Readiness Level is used to evaluate the maturity of WirlessHART technology which if successfully implemented will become the technology of the future.
