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
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.
