Accumulated Status, Status, and Fault Registers
TM-XR9B-01XN 3–17
Accumulated Status, Status, and Fault Registers
The Ethernet/RS-232 Interface card uses three separate registers which
are always active. They are the accumulated status, status, and fault
registers. You can use the status commands shown in
Table 3-6, “Status
Commands” on page 3–8 to activate the registers. The bit register has
twelve conditions, each assigned a bit weight. When querying a register,
the controller returns a response which is the sum of the weights of all
relevant conditions.
Example
:
The accumulated status register shows that PON, REM, CC and CV have
all been active since the last accumulated status register query.
Table 3-8 shows the mnemonics and bit weights which correspond to each
register condition. You can select conditions you want to monitor in the
fault and status register by using the MASK and UNMASK commands.
ASTS? Query the Accumulated Status register.
ASTS 771 Controller response.
771 = 512 + 256 + 2 + 1 = PON + REM + CC + CV
