The Value of Advanced Operator Displays
The Operator interface to your control system is an important part of the Operator’s ability to control the plant process. A well-designed graphic that encourages situational awareness allows for a more accurate and timely Operator response.
By using leading indicators, deviating process values can be easily identified and corrected before they alarm or trip. Alarms and other abnormal events should clearly stand out on the graphics by using specific colors and shapes allowing for easy identification of a process change. Large Screen Overview displays provide an at-a-glance view of the Operator’s entire span of control using strategically identified variables. Task-oriented displays provide all necessary information for control during common operating scenarios on a single display. Permissive and shutdown graphics clearly illustrate what is preventing start-up or what caused a shutdown.
