Tracking/Timeout Errors

Wednesday, August 24, 2016 2:29 PM

Problem(s) Encountered:

Occasionally (about 5 times throughout the night), TCS would show a red error in the status line that read  send failed for command track: network operation timed out.   TCS would seem to stop updating, but we were able to solve the problem by turning tracking off and back on again.  It was annoying, but it didn''t end up being much of a problem.  I can''t think of any specific cause for the error, because it would go off somewhat randomly.

Once it went off in the middle of an exposure, and once it went off when we were slewing.  


Solutions:

Ran the telescope, with dome to various positions and let it track.  Did this for about 5 hours without any errors at all.  After stowing everything, I did go ahead and and close the TCS GUI.  Then from a mdm13ws1 terminal window, I reset the telescope servers by issuing telescope stop then telescope start commands.  GUI was reopened and initialized.  If the problem persists, I can go a little deeper.
