ChxxData
(Ch00…Ch15)
REAL Float Value of analog signal on Channel xx 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.

ChannelFaults
(bit0…15)
INT Binary Indicates a problem with analog data on Channel x or broken communication between the Logix
controller and the 1756-IF16H module.
Example: Set if analog signal is larger than 20 mA.
ChxxFault
(Ch0…Ch15)
BOOL Decimal ChannelFaults.0…ChannelFaults.15
Module Status SINT Binary
Calibrating BOOL ModuleStatus.0, Calibration in progress
UpdatedStatusReady BOOL ModuleStatus.1, Module has collected updated Additional Device Status from HART command 48.
This status can be retrieved by using the Read Additional Status service, 16#4C. For more
information about this service, see Read Additional Status (Service Code = 16#4C) on page 125
.
ModuleFaults
(bits0…5 not used)
SINT Binary
CalFault BOOL Decimal ModuleFaults.6, 1756-IF16H Module Calibration Failed.
AnalogGroupFault BOOL Decimal ModuleFaults.7, Indicates a fault has occurred on any channel (any of ChannelFaults).
