Reference: Error/Status Register Information
Summarized below are various registers that provide the instrument with error/status information. This information is normally presented in
the configuration software’s Fault Log tab. Digital busses (such as HART) can also access this information via a read operation using the
appropriate register address.
Instrument Fault Codes Tables
The basic CORE fault register (4 bytes) provides basic CORE and FE fault indication. Detailed faults are given in the 6-byte detailed
CORE fault register and the 4-byte FE fault register. The latter two registers provide specific error status for a fault indicated by the basic
CORE fault register.

software’s Core Faults tab (Factory branch menu tree – requires entry of appropriate level password).
