ADVISABLE STATE OF CONTROLLED OBJECTS IN FACTORY AUTOMATION SYSTEMS

摘要

An advisable state notification framework for an operator interface system is provided. Advisable states represent events detected within an industrial system that are less critical than alarm events but that nevertheless warrant notification. The framework supports multiple classes of advisable states, which are configured and handled separately from alarm states. Each class of advisable state is notified using a unique graphical icon. Moreover, the framework distributes advisable state icons on selected screens throughout the display screen navigational hierarchy to guide the operator to screens that identify the source of the advisable state. The notification and guidance features are inherent to the operator interface development environment, accelerating development time and reducing the need to create a custom notification framework.
