ChannelFaults
(Ch00…Ch15) INT Binary Indicates a problem with analog data on Channel xx or broken communication between the Logix
controller and the 1756-IF16H module.
Example: Set if analog signal is larger than 20 mA.
ChxxFault BOOL ChannelFaults.xx
ModuleStatus SINT Binary
Calibrating BOOL Decimal ModuleStatus.0, Calibration in progress.
UpdatedStatusReady BOOL Decimal 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 SINT Binary
CalFault BOOL ModuleFaults.6, 1756-IF16H module calibration failed.
AnalogGroupFault BOOL Decimal ModuleFaults.7, Indicates a fault has occurred on any channel (any of ChannelFaults).
Ch00 AB:1756_IF16H_HARTDataAll_Struct:I:0, Channel 00 analog and HART data.
Data REAL Float Analog value in engineering units.
DeviceStatus AB:1756_IF16H_HARTStatusAll_Struct:I:0, Channel 00 HART Device status info.
HARTInit BOOL Decimal 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-IF16H is sending out HART messages attempting to establish
communication with a HART device.
HARTCommFail BOOL Decimal 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 Decimal Pass-through message reply is ready for query service.
CurrentFault BOOL Decimal Analog current measurement does not match the current the Field Device reported over
the HART network.
