Module Data Types - 1794-IE8H, 1797-IE8H

The table below lists and describes the module-defined data types for the 1794-IE8H and 1797-IE8H modules. It includes information for input (as indicated by an "I") and configuration (as indicated by a "C").

TIP:

FLEX Ex I/O is based on 16-bit INTs and not 32-bit DINTs. Using 16-bit INTs in instructions that are optimized for 32-bit DINTs may decrease performance with certain instructions.

Module-defined Data Type: AB:1797_IE8_HART:I:0

Member Name	Type	Default Display Style	Description
Fault	DINT	Binary	Fault - Used for Input Data Validation 0 = Valid Data 1 = Invalid Data - if the connection to the module has been lost, or if the module has a severe hardware fault, the lower 8 members are set to 1.
Ch0Data Ch1Data Ch2Data Ch3Data Ch4Data Ch5Data Ch6Data Ch7Data	INT	Decimal	Input data for the selected channel.
Alarms	INT	Binary	Alarms data.
Ch0Underrange Ch1Underrange Ch2Underrange Ch3Underrange Ch4Underrange Ch5Underrange Ch6Underrange Ch7Underrange	BOOL	Decimal	Underrange-set if the input signal is below the input channel’s minimum range. Ch0 corresponds to channel 0, Ch1 corresponds to channel 1, etc. up to Ch7 corresponding to channel 7.
Ch0Overrange Ch1Overrange Ch2Overrange Ch3Overrange Ch4Overrange Ch5Overrange Ch6Overrange Ch7Overrange	BOOL	Decimal	Overrange-set if the input signal is above the input channel’s maximum range.
Status1	INT	Binary	Alarms data.
Ch0LocalFault Ch1LocalFault Ch2LocalFault Ch3LocalFault Ch4LocalFault Ch5LocalFault Ch6LocalFault Ch7LocalFault	BOOL	Decimal	This member is set when the loop to the transmitter or field device is open or shorted.
Ch0RemoteFault Ch1RemoteFault Ch2RemoteFault Ch3RemoteFault Ch4RemoteFault Ch5RemoteFault Ch6RemoteFault Ch7RemoteFault	BOOL	Decimal	This member is set when the Remote Transmitter Error Up or Down is selected and there is an alarm from the remote transmitter indicating transmitter difficulties, sensor difficulties, or the loop to the sensor is open. If not using a remote transmitter then the bit for the channel indicates a high-high or low-low alarm.
Status2	INT	Binary	Diagnostic data.
Ch0DiagnosticStatus0 Ch1DiagnosticStatus1 Ch2DiagnosticStatus2 Ch3DiagnosticStatus3	BOOL	Decimal	Diagnostic Data: 0=normal, 1=calibration failure, 2=configuration failure (bad Data Format selected), 3=message failure, 4=lead break detection hardware failure, 5=major hardware failure, 6=EEPROM failure, 7=RAM failure, 8=ROM failure, 9=calculation failure, 10-15 are unused.
StatusHARTFailure	SINT	Binary
StatusHARTReadBack	SINT	Binary
StatusHARTComm	SINT	Binary
StatusHARTTransmitList		Binary
