Device Status
HART defined device status information is available Only those bits supported by the M2000 are listed in the table below All
other bits will be set to 0
Bit
Description
Comments
0
PV Out of Range
Set if the primary variable is exceeding the sensor limits
1
Non PV Out of Range
Not Used
2
PV Output Saturated
Set if the primary variables analog loop current exceeds the limits of 4 mA and 20 mA
3
PV Output Fixed
Set if the daughterboard is configured for multi-drop mode and the polling address is
non-zero When set current is fixed at 4 mA
4
More Status Available
Set when alarm or failure is detected Refer to command #48 for further information
5
Device Reset
Set at power-up or on reset of the meter
6
Configuration Changed
Indicates when M2000 configuration has been changed This bit can be cleared by
Universal command #38
7
Field Device Malfunction
Set when there is failure of the M2000 that prevents flow measurement
