The Telescope Interlock Manager (TIM) is the HMI display the provides current information about the Global Interlock System via a touch screen display. The primary display is located at the Utility Level and a secondary display is in the control room.
The various displays form a hierarchical structure of information.
The HMI were designed using the principles of Abnormal Situation Management or ASM. In general, the use of color is reserved to indicate an abnormal condition (i.e. non-operational or restricted operation condition). Red usually denotes an interlock condition is present. Blue usually indicates a required action must be preformed to restore operation. Yellow usually indicates a restricted condition (such as a speed limit). Orange usually indicates a warning about a potential hazard (such as a limit being overridden). Green is avoided because of potential issues with red-green colorblindness.
Main Display
The main display provides access to the view the various axes of motion and other subsystem, plus the ability to view diagnostic information. There is the ability to login to view interact with restricted information (such as the re-home the safety encoders).
GIC Display
This page provides at-a-glance status of the state of the Global Interlock System. It shows if the various controllers are on-line, running, safety signed, and/or safety locked. In addition it provides information on the time synchronization, communication, safety instructions, emergency stops, and major permissive signals.
