Category: Mechanism Command
 
Description: This command determines the status of the INGRID EPICS Controller and all INGRID mechanisms.

If all is well the position and status of each mechanism is reported and the user is informed that the INGRID EPICS Controller is ready for observing. If all is not well diagnostic information is displayed to provide clues as to the cause of the fault and possible corrective actions.

This command is the primary diagnostic tool where problems are encountered during mechanism movement, or if the data acquisition system warns that it was unable to build the INSTINGR mechanism status packet. 

The command is able to diagnose and report on the following faults:

  • EPICS CA Repeater Task not loaded.
  • EPICS Controller not online.

    •  
Assuming none of the above fault conditions exist the command reports the status of:
  • EPICS Controller software identifie.
  • Pupil Stop Wheel status.
  • Filter Wheel 1 status.
  • Filter Wheel 2 status.
  • Pupil Imager status.
  • Focus Drive status.
The information provided by this command is complemented by the wheelcon command which reports the names of filters, pupil stops etc loaded into INGRID's mechanism wheels.
 
Arguments: None
