More Status Available

More status information is available via Command 48. Read Additional Status information. The connector will execute Command 48 if configured to collect Additional Device Status and this bit is set.

Loop Current Fixed

The Loop Current is being held at a fixed value and is not responding to process variations.

Loop Current Saturated

The Loop Current has reached its upper (or lower) endpoint limit and cannot increase (or decrease) any further.

A Device Variable not mapped to the PV is beyond its operating limits.

Primary Variable Out of Limits

The PV is beyond its operating limit.

Maintenance Required

This bit is set to indicate that, while the device has not malfunctioned, the Field Device requires maintenance. Devices supporting this bit should support the Condensed Status Commands.

Device Variable Alert

This bit is set if any Device Variable is in an Alarm or Warning State. The host should identify the Device Variable(s) causing this to be set using the Device Variable Status indicators.

Critical Power Failure

For devices that can operate from stored power. This bit is set when that power is becoming critically low. For example, a device scavenging power losing that power source would set this bit. Devices must be able to sustain their network connection for at least 15 minutes from the when this bit is set. A device may begin gracefully disconnecting from the network if its power level drops too low.

Failure

When this bit is set one or more Device Variables (i.e., measurement or control values) are invalid due to a malfunction in the field device or its peripherals. Devices supporting this bit must support the Condensed Status Commands.

Out of Specification

When set, this bit indicates deviations from the permissible ambient or process conditions have been detected that may compromise measurement or control accuracy (i.e., device performance may be degraded given current operating conditions). Devices supporting this bit must support the Condensed Status Commands.

Function Check

This bit is set if one or more Device Variables are temporarily invalid (e.g. frozen) due to ongoing work on the device. Devices supporting this bit must support the Condensed Status Commands.

Standardized Status 0

Status commonly used in a wide range of devices and device types. Any bit not specified is 'Undefined' and must be set to zero.

The "Map" column indicates the default mapping to Condensed Status (F=Failure; C=Function Check; S=Out of Specification; M=Maintenance Required; N=No Effect).

Standardized Status 1

(If supported)

Status commonly used in a wide range of devices and device types. Any bit not specified is 'Undefined' and must be set to zero.

The "Map" column indicates the default mapping to Condensed Status (F=Failure; C=Function Check; S=Out of Specification; M=Maintenance Required; N=No Effect).

Analog Channel Saturated

(If supported)

Any bit not specified is 'Undefined' and must be set to zero.

The "Map" column indicates the default mapping to Condensed Status (F=Failure; C=Function Check; S=Out of Specification; M=Maintenance Required; N=No Effect).

Standardized Status 2

(if supported)

Any bit not specified is 'Undefined' and must be set to zero.

The "Map" column indicates the default mapping to Condensed Status (F=Failure; C=Function Check; S=Out of Specification; M=Maintenance Required; N=No Effect).

Standardized Status 3

(If supported)

The status byte is reserved for WirelessHART standardized status. Any bit not specified is 'Undefined' and must be set to zero.

The "Map" column indicates the default mapping to Condensed Status (F=Failure; C=Function Check; S=Out of Specification; M=Maintenance Required; N=No Effect).

Analog Channel Fixed

(If supported)

Any bit not specified is 'Undefined' and must be set to zero.

The "Map" column indicates the default mapping to Condensed Status (F=Failure; C=Function Check; S=Out of Specification; M=Maintenance Required; N=No Effect).

Standardized Status 0: Device Variable Simulation Active

The device is in simulation mode and one or more of its Device Variables are not representative of the process.

Standardized Status 0: Non-Volatile Memory Defect

The Non-Volatile memory check is invalid or maybe corrupt, or the battery of a battery-backed memory is defective.

Standardized Status 0: Volatile Memory Defect

The RAM memory check is invalid or maybe corrupt.

Standardized Status 0: Watchdog Reset Executed

A watchdog reset has been performed.

An internal or environmental condition is beyond acceptable limits.

Standardized Status 0: Electronic Defect

A hardware problem not related to the sensor has been detected.

Standardized Status 0: Device Configuration Locked

Device is in write-protect or is locked.

Standardized Status 1: Status Simulation Active

Status Simulation Mode has been enabled and the Device Status and the status bits being returned in the Command 48 response are fixed and may not represent the current state of the device.

Standardized Status 1: Discrete Variable Simulation Active

The device is in simulation mode and one or more of its Discrete Variables are not representative of the process.

Standardized Status 1: Event Notification Overflow

This bit must be set when the event queue for one or more Event Specification (see

Event Notification in Common Practice Command Specification

) overflows resulting in an event not be recorded. This bit must be reset when all pending events have been acknowledged.

Standardized Status 2: 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. Issuing Command 74 to read "Number of devices detected" resets this bit. The current sub-device list is read using Command 84.

Standardized Status 2: Duplicate Master Detected

The Adapter has discovered another master with the same address connected to its token-passing interface.

Standardized Status 2: Sub-Device Mismatch

One or more of the sub-devices connected to the I/O system do not match the stored/pre-configured value.

This bit is set when the Stale Data Alarm for any Sub-device is set.

Standardized Status 3: Capacity Denied

The device was unable to acquire the communication bandwidth required to support the Burst Messaging specified. This must also be set if the Network Manager reduces the bandwidth allocated to the device. Gateway must set this bit when any device in the network has insufficient bandwidth.

Standardized Status 3: Bandwidth Allocation Pending

The device has asked for bandwidth from the Network Manager and is awaiting Network Manager response.

Standardized Status 3: Block Transfer Pending

The device has a data set (e.g., a waveform) awaiting transfer to the host application or Gateway. The Gateway should open the block transfer port and transfer the data.

Standardized Status 3: Radio Failure

The radio or radio module has failed and the device needs to be serviced or replaced. The "Device Malfunction" bit in the Device Status byte must be set when this bit is set.
