On Graphics and Indication in Unit Control

Fundamentally an operator interacts with an equipment based automation control system by means of a touch panel, push-buttons, panel alarms, lights, hooters and at least one key graphic display.

Today I am in the Worthing, UK, home of Invensys Eurotherm and had an opportunity to talk with some of the Senior Engineers and think about the life of an plant operator and the use of these devices. As a result I decided to focus this post on three aspects:-

• Hands-Free Indication
• Primary Panel Graphics
• State of Play Indication

All three aspects need to be taken into consideration in the implementation of packaged control solutions.
