Bit Mask Definition
0×80 = 1= Communication Error
0 = Response Code
0×40 = Vertical Parity Error
Bits 6..0 = Enum 0 to 127, command-
dependent
0×20 = Overrun Error
0×10 = Framing Error
0×08 = Longitudinal Parity Error
0×04 = Reserved, always 0
0×02 = Buffer Overflow
0×01 = Reserved, always 0
HART STATUS BYTE 2: Field Device Status
This is the second status byte returned in a Slave-to-Master frame:
Bit Mask Definition
0×80 = Device Malfunction
0×40 = Configuration Changed
0×20 = Cold Start
0×10 = More Status Available
0×08 = Loop Current Fixed
0×04 = Loop Current Saturated
0×02 = Non-Primary Variable Out of Limits
0×01 = Primary Variable Out of Limits
HART STATUS BYTE 3: Extended Device Status
This is the first byte returned with Command 9 by HART revision 6 and 7
devices. It is not used and always zero (0) for HART revision 5 devices:
Bit Mask Definition
0×04 = Critical Power Failure
0×02 = Device Variable Alert
0×01 = Maintenance Required
