Practical Data Communications & Networking for Engineers & Technicians

THE WORKSHOP

Practical data communications and networking for engineers and technicians is a comprehensive workshop. It covers RS-232, RS-422, RS-485, industrial protocols, industrial networks and the communications requirements for 'smart' instrumentation. It will equip you with the tools to analyse, specify and debug data communications and networking systems in the instrumentation and control environment.

This workshop is designed to benefit people who are involved in specifying, commissioning and debugging data communications and networking systems for instrumentation and control, but who have little previous experience in this area. It has been structured to cover the main concepts of data communications, to clarify their meaning and to describe their applications in modern process control and automation systems.
