How should DES represent its system? E.g. as a
state machine? For now, make tables for the
FCS and for the IB, of the senders and receivers
of 1. the Control and State information 2. the
Data

The Data (IB/QA?DB) will include diagnostic and
monitoring data. What information needs to be
collected for the history displays, from the data
and from the metadata ? E.g., occupancy/CCD,
ltPHgt /CCD. Other questions, also about the
data flow, outside FCS and IB, include Who
will be responsible for the DTS ? (SISPI or
NOAO)Will the DTS send data to DM, and to the
local data storage on the mountain (3 days
worth) ? Display Gui will it need to have
access to all pxl data, to make a partial HR
display, as well as a low resolution display of
the whole array?

CCD Readout and IB Data Base Requirements
For each CCD the DB has CCD orientation- will
all be the same? (archive)CCD geometric location
in the array (probably stable? archive) e.g.
relative location x,y of the bottom left pixel
x(1),y(1) CCD voltage rail requirements
stable? archive?DHE map (must be able to
change) PAN, Crate, preamp1 and 2 ACQ card
slot, ACQ Card ID, ADC subaddress CBB card
slot, CBB Card ID, CBB subaddressDead channels,
light bulbs, defects etc special infoWe have to
be able to find DHE info for geometry key and
