A.3.3 HART CMD48 Read Additional Status Information
Command 48 returns device status information not included in the response code or device status
byte of Command 3. All field devices support at least bytes 0 ... 8. If a field device supports more
than one analog channel, then bytes 9 ... 13 will be supported as well.

Status
(Device-specific status 4) • 0x01 Maintenance Required
• 0x02 Device Variable Alert
• 0x04 Critical Power Failure
5 Device Operation in Progress
(Device-specific status 5) • 0x02 “Configuration Changed bit reset” procedure
• 0x04 “Sub-Device update” procedure
• 0x08 “Device update” procedure
6 Extended device status Not relevant for Gateway, always set to "0"
7 Device operating mode For future expansions, always set to "0"
8 Standardized status 0 • 0x01 Simulation active
The device is in simulation mode and one or more of its device variables
are not representative of the process.
• 0x02 Non-volatile memory defect
The non-volatile memory check is invalid or maybe corrupt, or the
battery of a battery-powered memory is defective
• 0x04 Volatile memory defect
The RAM memory check is invalid or maybe corrupt.
• 0x08 Watchdog reset executed
A watchdog reset has been executed.
• 0x10 Power supply conditions out of range
The power supply is outside its allowable range.
• 0x20 Environmental conditions out of range
An internal or environmental condition is beyond acceptable limits.
• 0x40 Electronic defect
A hardware problem not related to the sensor has been detected.
9 Standardized status 1 For future expansions, always set to "0"
10 Analog channel saturated Not relevant for Gateway, always set to "0"
11 Standardized status 2 • 0x01 Sub-device list changed
When set, the I/O system has lost communication with one of its sub-
devices or discovered a new sub-device. This bit is reset if command 74
"Number of devices detected" is issued. The current sub-device list is
read using command 84.
• 0x02 Duplicate master detected
The adapter has discovered another master with the same address
connected to its token-passing interface.
