Supervising the Process
From a monitoring and control standpoint, the most important module is Supervise. It’s here that the mimic is on-line and continuously reflects changes in the process. It’s also here that operators and plant personnel are given tools for a quick and effective overview and intervention.
The Active Alarms list is always present and can be brought up in three separate ways: by clicking on its icon on the mimic, by clicking on its icon in the Windows system tray and by clicking on the minimized program name on the Windows status bar. The alarm list provides an instant overview of the total number of active alarms in the process, what condition is causing the alarm, where the process component is located that’s in an alarm state, the date and time of alarm activation, and much more. Alarm acknowledgment is a simple mouse click away and the acknowledging operator can be logged. Please see the topic: Alarm Precision and Flexibility
From the Graph menu in Supervise, graphs and trends on process components are easily accessed by the operator. These graphs are either pre-configured by the system designer or they are generated on-the-fly by the operator himself. Time intervals are also user or operator defined for how far back in time the trend curve is to be extended. Please see the topic: Graphs and Trends

Report generation is also an integral part of Supervise. Under the User Programs menu, the operator can himself generate the two types of standard reports included with the IGSS system, the Snapshot report and the Periodical report. These can instantly be viewed on screen or they can be printed out. Please see the topic: IGSS Reports
Toggling the Mimics
If it’s necessary to toggle between several mimics in the process, the desired mimic is easily found in the Diagram menu and chosen. Alternatively, the system designer can include buttons directly on one mimic or diagram, which when clicked upon by the operator, immediately brings up the next required mimic or diagram.
