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 Response Code
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.
