Tag Definitions Appendix A
ConfigurationChanged BOOL Decimal The field device configuration has changed and new field device configuration information can be
obtained from the 1756-IF16H module via CIP MSG GetDeviceInfo, which will clear this bit.
MaintenanceRequired BOOL Bit 0 of Extended Device Status (if using CMD 9, or from CMD 48 if supported).
BrokenWire BOOL Decimal Indicates that current is not flowing through the module as expected. This might be caused by
broken wiring, RTB removal, or a powered-off field device.
HARTFault BOOL Decimal Indicates a problem with HART data from the field device on Channel x.
Examples are HART not enabled, HART device not connected, HART communication failure
due to noise.
The following Field Device Status conditions also cause this to be set: Device Malfunction,
PV Out of Limits, Loop Current Saturated, and Loop Current Fixed.
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.
AlarmStatus SINT Binary Indicates various alarms on the analog signal.
DeviceVariableAlert BOOL AlarmStatus.4, Bit 1 of Extended Device Status. Device reports a problem with some measurement.
Overrange BOOL AlarmStatus.5, Signal value over range (over 20 MA).
Underrange BOOL AlarmStatus.6, Signal value under range.
(less than 3.4 mA if configured for 4…20 mA).
CalFault BOOL AlarmStatus.7, Bad calibration.
PV REAL Float Primary value. This is the same value as signaled on the analog channel and is the most important
measurement made by this device.
SV REAL Float Secondary value
TV REAL Float Third value
FV REAL Float Fourth value
PVStatus SINT Hex Primary status
16#C0 = Connected
16#00 = Not Connected
SVStatus SINT Hex Secondary status
16#C0 = Connected
16#00 = Not Connected
TVStatus SINT Hex Third status
16#C0 = Connected
16#00 = Not Connected
FVStatus SINT Hex Fourth status
16#C0 = Connected
16#00 = Not Connected
