STATUS REPORTING STRUCTURE

The status reporting of the BOP uses four status registers, illustrated in Figure 3-20. These reg-
isters are the Questionable, Operation, Standard Event and Service Request registers. The
Questionable and Operation registers are 16 bit registers and the Standard Event and Service
Request registers are 8 bits. These four registers are referred to as condition registers. Each of
the four condition registers is associated with two related registers: an event register which
holds unlatched events reported in real-time by the instrument and is cleared by reading the
register, and an enable register which allows the contents of the event register to be passed
through to set the associated condition register.
