Data Communication & Field Bus Systems
Data Communication & Field Bus Systems
INTRODUCTION
The increasing trend towards digital communications within the industrial plant environment has brought in its wake a myriad of problems concerned with interconnectivity and differing standards offered by a wide variety of competing vendors. For the user, it has become progressively more difficult to differentiate between the proffered options.
This workshop, Data Communications and Fieldbus Systems, is designed to provide engineers and technicians with an overview of modern digital communication standards .
