If a server fails, the secondary server takes over. Because of the seamless nature of this action, the user usually does not even realize that a server has failed. In addition to the fault tolerant set up, Case Services software also acts as a constant back up for the field controllers. Since each controller s set-up parameters are saved in the host database when uploaded from the controller, the host database acts as a backup for the controllers. If a controller loses its parameter settings because of a power failure or other reason, those parameters can be downloaded from the host to the affected controller in a few seconds when needed.
Users can then see trends, alarms, and reports on their individual desktops.
For example, one customer added 55 RTUs with over 1200 associated points in just two days. Once points are added, users can track trends, print reports, and perform analyses. Users can easily add calculated analog, meters, and discretes based on database information for alarms and instant notification of problems. The real-time system is integrated with other Case Services products. It can also be readily integrated with any other MMI solution for providing site-specific graphical interfaces.
