Figure 3 The Registers and Filters for a Node
The Operational/Questionable Slot Status Event Register (OSSER/QSSER)
contains the status of a particular module slot. A bit changes from 0 -> 1
when an event occurs, for example, when a laser is switched on. For
details of the function of each bit of these registers, see
Operation/Questionable Status Summary Register
The Operational/Questionable Slot Enable Status Mask (OSESM/QSESM)
allows you to choose the events for each module slot that may affect the
Operational/Questionable Status Event Register (see below). If you set a
bit of the OSESM/QSESM to zero, the occurence of the corresponding
event for this particular module slot cannot affect the
Operational/Questionable Status Event Register. The default is for all the
bits of the OSESM/QSESM to be set to 0.
The Operational/Questionable Status Event Summary Register
(OSESR/QSESR) summarizes the status of every module slot of your
instrument. If, for any slot, any bit of the QSSER goes from 0 -> 1 AND the
corresponding bit of the QSSEM is 1 at the same time, the QSESR bit
representing that slot is set to 1.

Event Registers
A positive transition in the condition
register, when a bit changes from 0 -> 1,
causes the corresponding bit of the
corresponding event register
to change from 0 -> 1.
