Member Name Type Style Description
ChannelFaults
(bits 9…15 unused) INT Binary
ChxFault BOOL ChannelFaults.x
LoopOutputFault BOOL Decimal ChannelFaults.8, This is a hardware fault where the module has detected that the power supply to
the isolated(analog) side of the board has failed(no power). It does not roll into any other bits. The
OK status indicator is set to solid red.
ModuleFaults SINT Binary
CalFault BOOL Decimal ModuleFaults.1, 1756-OF8H module calibration failed.
Calibrating BOOL Decimal ModuleFaults.2, Calibration in progress.
UpdatedStatusReady BOOL Decimal ModuleFaults.3, 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 .
AnalogGroupFault BOOL Decimal ModuleFaults.7, Indicates a fault has occurred on any channel (any of ChannelFaults).
Ch0 AB:1756_OF8H_HARTDataAll_Struct:I:0, Channel 0 analog and HART data.
Data REAL Float Analog value in engineering units.
DeviceStatus AB:1756_OF8H_HARTStatusAll_Struct:I:0, Channel 0 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-OF8H 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 is valid.
(HART.PVStatus will be set to 0 to also indicate this.)
MsgReady BOOL Decimal Pass-through message reply is ready for query service.
