Tag Definitions Appendix A
CurrentFault
BOOL
Analog current measurement does not match the current the field device reported over
the HART network.
ConfigurationChanged
BOOL
The field device configuration has changed and new field device configuration information can be
obtained from the 1756-IF8H module via CIP MSG GetDeviceInfo, which will clear this bit.
ResponseCode
SINT
Binary
HART communication status byte or Response code from a recent HART reply. See
and Field Device Status on page 195
for more information.
FieldDeviceStatus
SINT
Binary
HART device status byte from a recent HART reply. Indicates the health of the HART field device.
See
Field Device Status Bit Mask Definitions on page 196
for more information.
PVOutOfLimits
BOOL
Decimal
The primary variable is beyond its operating limit.
VariableOutOfLimits
BOOL
Decimal
A device variable not mapped to the PV is beyond its operating limits.
CurrentSaturated
BOOL
Decimal
The loop current has reached its upper or lower endpoint limit and cannot increase or decrease
any further.
CurrentFixed
BOOL
Decimal
The loop current is being held at a fixed value and is not responding to process variations.
MoreStatus
BOOL
Decimal
More status information is available via command 48, ‘Read Additional Status’ information.
ColdStart
BOOL
Decimal
A power failure or device reset occurred.
Changed
BOOL
Decimal
An operation was performed that changed the device’s configuration.
Malfunction
BOOL
Decimal
The device detected a serious error or failure that compromises device operation.
ExtDeviceStatus
SINT
Binary
Extended device status byte.
Maintenance
Required
BOOL
Decimal
Maintenance is needed.
DeviceVariableAlert
BOOL
Decimal
Device variable alert.
PowerLow
BOOL
Decimal
Low power.
