Description

STS?
**STS XXX
Used to read the contents of the
status register, which maintains the present
status of the power supply. See Table 3-9
for a description of each bit in the status
register, and the bit weight for each
condition.
3-161-3-164
ASTS?
**ASTS XXX
Used to read the contents of the
accumulated-status register, which stores
any bit that was entered in the status
register since the accumuiated-status
register was last read, regardless of whether
the condition still exists. The bit descriptions
and weights are the same as in the status
register, see Table 3-9.
3-165-3-167
UNMASK mnemonics
^UNMASK XXX
Determines which conditions are
capable of setting bits in the FAULT
register; therefore, allows operator to define
which conditions are fault conditions. Condi¬
tions can be enabled either by sending a
string of mnemonics after the command
UNMASK, or by sending the decimal
equivalent of the total bit weight for all con¬
ditions to be enabled. The mnemonics and
bit weights are the same as in the status
register, see Table 3-9. Mnemonics are
separated from each other by commas, and
may be sent in any combination and in any
order. The command UNMASK NONE
disables all conditions from setting bits in
fault register.
Initial Condition: UNMASK NONE
3-168-3-172
UNMASK?
**UNMASK XXX
Used to read which bits in the status
register have been enabled to set bits in the
fault register (i.e.,which power supply condi¬
tions are defined as faults), xxx is decoded
using bit weights in Table 3-9.
3-173
FAULT?
**FAULT XXX
Used to read which bits have been set
in the fault register. A bit Is set in the fault
register when the corresponding bit In the
status register changes from inactive to ac¬
tive AND the corresponding bit in the mask
register is set. Bits in the fault register are
reset only after the fault register is read, xxx
is decoded using bit weights in Table 3-9.

'SRQ OFF
SRQO
V.
fSRQ ON
ISRQ 1
Enable or disable power supply's
ability to request service from the controller
for fault conditions. UNMASK command
defines which power supply conditions
SRQ are defined as faults.
Initial Condition: SRQ OFF
