Status information

Status information is returned from the 4MS systems to the 4000 control computer using the same procedure as is described above for instrument control. Status information received by the d-tasks is posted on a 'notice-board' maintained in memory by the ADAM system. Error messages are reported to the observer (usually).

A mimic task is responsible for picking up information from the notice-board and displaying it on the mimic screen. This is a multi-page status display, providing one or more pages of status information for each sub-system. The user determines which page is to be displayed using a mouse and menu.
