The Supervise program is part of the IGSS (Interactive Graphical SCADA System). The Supervise program is a tool for online process monitoring and operator control based on the latest standards of interactive operation using screen, mouse and keyboard.
A set of pictures - called process diagrams - present the plant or process graphically on your PC screen. Each diagram consists of a static background picture and dynamic symbols representing the plant’s working components (motors, valves, flow meters, temperature scales, etc.). States and values of these process objects, also called process components, are updated automatically each time they change. Click-sensitive areas give you operator access to the process diagram; they bring up another diagram or open a command box, for example.
u Diagrams and areas
The first thing for you to know is that the IGSS screen representation of your plant or process is subdivided into areas and diagrams
Typically, a process diagram may be opened from the Diagram menu. The pictures that you see in the Diagram menu all belong to the same part of the process, the same area. If you select another area from the Area menu, you will see other pictures for selection in the Diagram menu.
u Graphs
Graphs opened from the Graph menu allow you to have process values presented in curve charts so that you can evaluate their variation with respect to time. We distinguish static and dynamic graphs, graphs that are predefined by the system designer and those that you can define yourself on-the-fly during online process monitoring.
u Controlling process objects
The Supervise program allows you to directly intervene in the plant and process operation provided you have the right access authority assigned to your user name and password.
Clicking on a dynamic object in a process diagram displays the principal characteristics of the component in the status bar at the bottom of the process diagram window. At the same time a popup menu appears. It gives you direct access to the Properties menu of the object and also displays the object commands which you can trigger with a simple mouse click; commands such as opening or closing a valve, adjusting a limit or setpoint value.
u Handling process alarms
When a component in the process is in some way faulty, if for instance a valve is open when it should be closed or some level in a tank is too high, an alarm may be triggered. In this case, the symbol representing the faulty component will typically flash in red. Simultaneously, all details about the alarm situation are registered in the alarm list. You gain access to this list by clicking the Active Alarms button in the taskbar at the bottom of the screen, or by double-clicking on the alarm icon.
In the alarm list, instructions on how to handle the alarm may be attached and you yourself may describe how you resolved the problem in a note that is automatically attached to the alarm.
The alarm can be acknowledged the moment it arises but remains in the list of alarms until the error situation in the process is resolved. After that, the alarm is automatically transferred to the alarm log.
Throughout online process monitoring, and even when you turn to other programs on your PC, the alarm icon will remain visible, always informing you about the current alarm situation. Double-clicking on the alarm icon takes you directly into the alarm list and the Alarm program for further alarm handling.
u Printing out process information
All process information can be printed out, be it a screen dump of a complete process diagram, the contents of the alarm list or log, a graph or the values of process objects.
u Plant reports
The system has built-in facilities for generating operational reports and automatically keeps track of when the last report was created and printed. These report facilities are defined by the system designer and are usually made available to the plant operator in the form of User Programs.
Reports may be displayed in several formats. In most cases, the standard IGSS reports will fulfil your documentation requirements. Special requirements can be taken into account by customised reports which again are called up by the operator under the menu function User Programs.
