4.1.4 System Controller

The CHART II system will provide a system controller for all subsystems to report status information. The system controller will poll each sub-system or connections to legacy systems for system health information. All failures shall be written out to a log (which can be viewed and printed through the system health report), notify a designated operator through a system failure dialog box at the SOC, and page out to the system administrator or designee using the existing paging system.

The system controller, configured by the system administrator, will arbitrate control of devices and notify a designated operator at the SOC when conflicts occur. The system will provide a management tool to allow the system administrator to shift these responsibilities from user to user if necessary. The system controller will also arbitrate user responsibilities while logged in and will transfer responsibilities to another user both automatically, in case of shift change, or manually by an appropriate manager, if desired.
