Ch09Data REAL Float Value of analog signal on Channel 09 after conversion to engineering units.
Ch10Data REAL Float Value of analog signal on Channel 10 after conversion to engineering units.
Ch11Data REAL Float Value of analog signal on Channel 11 after conversion to engineering units.
Ch12Data REAL Float Value of analog signal on Channel 12 after conversion to engineering units.
Ch13Data REAL Float Value of analog signal on Channel 13 after conversion to engineering units.
Ch14Data REAL Float Value of analog signal on Channel 14 after conversion to engineering units.

CSTTimestamp DINT[2] Hex Timestamp taken at the time the input data was sampled in terms of Coordinated System Time,
which is a 64-bit value in microseconds coordinated across the modules in the 1756 backplane.
RollingTimestamp INT Decimal Timestamp taken at the time the input data was sampled in millisecond resolution.
HART AB:1756_IF16H_HARTData:I:0, Contains HART field device health and dynamic process variables.
Ch00DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 0 HART Device status info.
Init BOOL Searching for or Initializing HART device.
If this is 0 and Fail is 1, then HART is not Enabled on this channel.
If both are 1, then 1756-IF8H is sending out HART messages attempting to establish
communication with a HART device.
Fail BOOL HART communication failure or device not found or HART not enabled.
If this bit is 1, none of the other data in the HART part of the Input Tag are valid.
(HART.PVStatus will be set to 0 to also indicate this)
MsgReady BOOL Pass-through message reply is ready for Query service.
CurrentFault BOOL Analog current measurement does not match the current the Field Device reported over 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.
ExtDeviceStatus SINT Binary Extended device status byte.
Bit 0 is Maintenance Needed
Bit 1 is Device Variable Alert
Bit 2 is Low Power
Ch01DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 01 HART Device status info.
Ch02DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel02 HART Device status info.
Ch03DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 03 HART Device status info.
Ch04DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 04 HART Device status info.
Ch05DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 05 HART Device status info.
Ch06DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 06 HART Device status info.
Ch07DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 07 HART Device status info.
Ch08DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 08 HART Device status info.
Ch09DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 09 HART Device status info.
Ch10DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 10 HART Device status info.
Ch11DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 11 HART Device status info.
Ch12DeviceStatus AB:1756_IF16H_HARTStatus_Struct:I:0, Channel 12 HART Device status info.
