OPERATION
Instrument Faults Codes Table
With the 32-bit CORE fault register the least significant 16 bits (b0-b15) are used to indicate which FE is associated with a given error (b0­
b7 corresponds to FE1 through FE8, respectively). For example, if FE1 and FE2 experience a fatal fault, the CORE reports "An FE
reported a fatal fault" status (see below) with bits b0 and b1 set (0x03).
The 16-bit device registers provide specific error status for the FE pointed to by the CORE fault register.

Description
One or more FEs (indicated in bits 0-15) returned a
fatal fault bit in the "RF" response. Process data
from any FE reporting a fatal fault is not included in
the averaged data.
—
One or more FEs (indicated in bits 0-15) was
performing a self-test at the time the process data
was being obtained. Data from the FE under test is
not included in the averaged data.
A system (CORE) error was experienced while
attempting to collect the process data.
—
The FEs are, 1) not active, 2) reported fatal faults,
or 3) were non-operational, so no process data was
obtained.
Either the SD card could not be initialized (upon
power up or insertion), or an error occurred while
writing to the SD card.
This bit reflects the Alarm #1 status.
This bit reflects the Alarm #2 status.
This bit reflects the Alarm #3 status.
This bit reflects the Alarm #4 status.
This bit reflects the Alarm #5 status.
This bit reflects the Alarm #6 status.
