BrokenWireFaults
(bit0…15)
INT
Binary
Indicates that current is not flowing through the module as expected. This might be caused by
broken wiring, RTB removal, or a powered-off field device.
ChxxBroken Wire
BOOL
Decimal
BrokenWireFaults.0…BrokenWireFaults.15
HARTFaults
(Ch0…Ch15)
INT
Binary
Indicates a problem with HART data from the Field Device on Channel x.
Examples are HART not enabled, HART device not connected, HART communication failure due to
noise.
The following Field Device Status conditions also cause this to be set: Device Malfunction, PV Out
of Limits, Loop Current Saturated, and Loop Current Fixed.

BOOL
Decimal
HARTFaults.0…HARTFaults.15
Ch00Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch00Fault for Overrange, Underrange, and/
or CalFault.
Ch00Overrange
BOOL
Ch00Status.05
Analog signal is greater than or equal to the maximum detectable signal. Because the signal
cannot be measured, it may be significantly above the maximum value.
Ch00Underrange
BOOL
Ch00Status.06
Analog signal is less than or equal to the minimum detectable signal. Because the signal cannot be
measured, it may be significantly below the minimum value.
Ch00CalFault
BOOL
Ch00Status.07
Set if an error occurs during calibration for Channel x, causing a bad calibration. Also sets CalFault.
Ch01Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch01Fault.
Ch02Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch02Fault.
Ch03Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch03Fault.
Ch04Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch04Fault.
Ch05Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch05Fault.
Ch06Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch06Fault.
Ch07Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch07Fault.
Ch08Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch08Fault.
Ch09Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch09Fault.
Ch10Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch10Fault.
Ch11Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch11Fault.
Ch12Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch12Fault.
Ch13Status

Binary
Indicates various alarms on the analog signal. Also sets Ch14Fault.
Ch15Status
SINT
Binary
Indicates various alarms on the analog signal. Also sets Ch15Fault.
