From the user’s point of view, EXO4 is a ready-made program that, among other things, contains:
- Windows for monitoring and controlling the processes. These process windows contain process pictures, popup menus, and dynamic elements for displaying and, if required, changing values in the controllers, etc. Dynamic values in an open window are updated continuously when you have a connection to the controller whose values are displayed.
- The windows also contain buttons, click areas and popup menus to open other windows.
- Presentation of alarms and historical data
Besides a main computer, you may also have work computers. The work computers can display the same windows as the main computer and communicate with the controllers in the system via the main computer. Real-time values are transferred to EXO4 when required, for example, when the user opens a process window. Users with sufficient authority can change the values of parameters, setpoints, etc. in EXO4. All changes are immediately transferred to the controller. Alarms can be transferred e.g. at activation or at synchronization, which occurs at least once every 24 hours. The alarms are stored in a database on the main computer and can also be sent to mobile phones, using SMS via Nimbus Alarm Server. The user can view the alarms in different report windows in EXO4, and also acknowledge, block and unblock the alarms. Logged data is stored in the controllers and is normally transferred to the EXO4 main computer at synchronization, once every 24 hours. The main computer stores the values in a database. The user can view the values in charts and other types of reports.
