Mark, I have to say you are one heck of a guy! I think this is the best mailing list ever. I post a problem and instead of someday maybe getting an non-applicable answer, someone drops by my beamline and just fixes the problem for me! Now THAT is service :)


Thanks again for the help!

Hi David,

I just walked down to your beamline and fixed the problem.

You had a typo in your startup script, a missing ":" character in the
"seq" command.  So the SNL program was not connecting to any PVs. I
added the missing colon and now it works fine.

Hello Everyone,


I am again having some trouble with the system I last posted about on
March 17 2010.

We think one of our XMAP cards is flakey and are sending it in for
repair,
so I had to take the 8 channel installation, copy it, and reconfigure it

for 4 channels (changing the EPICS "Name" for the "IOC" and the
information about number and position of cards, etc).

The epics server starts and seems to run on the windows system that
is hosting it, and it is making PV's available, but we are still having
trouble.

I do not know if these same problems occured when I had configured it
for
8 channels (2 xmap cards) - the 2nd card flaked out between set up and
start of testing

Any advice or ideas on what might be going wrong would be much
appreciated.

PLEASE CC me directly on any responses as I am not a regular list
member.

Details below:

(As described by Bill Lavender)
If we set an acquisition time of 1 second or so using the 4 Element
Detector Control MEDM screen and then press the Erase/Start button,
the Acquiring indicator turns on, but it never changes back to Done.
Instead, Acquiring stays on indefinitely.

I see the same behavior from my C code:

1.  I send the value 1 to XMAP_4ch_med1:EraseAll.VAL using a call to
    ca_array_put_callback() and then wait for the callback to complete.

2. I then execute a synchronous group that does the following:

    Send 0 to XMAP_4ch_med1:PresetLive.VAL
    Send 1 to XMAP_4ch_med1:PresetReal.VAL
    Send 0 to XMAP_4ch_med1:mca1.PCT

3.  Then I send the value 1 to XMAP_4ch_med1:EraseStart.VAL using a call
    to ca_array_put_callback() and then wait for the callback to
complete.
    However, the callback never completes.

The call to XMAP_4ch_med1:EraseAll.VAL is redundant and I plan to get
rid of it, but the above sequence should work.  It does work for a
Vortex detector from the APS detector pool.
.

Thanks! David.
