80 COI/AZ30E–EN Rev. D
8.5.2 Field Device Status Second Byte
Second Byte Description
Bit #7 Field Device Malfunction

A hardware error or failure has been detected by the device.

Further information may be available through the Read Additional Transmitter
Status command.
Bit #6 Configuration Changed

A write command has been executed.

A set command has been executed.
Bit #5 Cold Start
Bit #4 More Status Available

More Status information is available than can be returned in the Field Device
Status . Command #48 Read Additional Status Information provides this
additional status information.

Set if any of the device-specific status bits in command #48 are set.
Bit #3 Primary Variable Analog Output Fixed

The analog and digital analog outputs for the Primary Variable are held at the
requested value. They do not respond to the applied process.

Primary analog output set to a fixed value via HART (or via the HMI) putting the
current output into test mode.
Bit #2 Primary Variable Analog Output Saturated

The analog and digital outputs for the 'Primary Variable' are beyond their limits
and no longer represent the true applied process.

Calculated Current Output 1 value is beyond the physical limits of the output.
Bit #1 Non Primary Variable Out of Limits

The temperature or cold junction cell voltage are beyond the operating limits of
the probe. The
Read Additional Transmitter Status command, #48, is required to
identify the variable.

Set if SV, TV or QV sensor limit failure diagnostic bits are set.
Bit #0 Primary Variable Out of Limits

The measured oxygen value is beyond the operating limits of the probe.

PV sensor out-of-limits diagnostic set.
