Module Data Types - 1797-OE8

The table below lists and describes the module-defined data types for the 1797-OE8 module. It includes information for input (as indicated by an "I"), output (as indicated by an "O"), 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.

IMPORTANT:

Some of the configuration information for this module is located in the output module-defined data type and is different than that on an RSLogix 5 system. Since this information is exposed differently in RSLogix 5 and RSLogix 5000 systems, you must remember to verify the configuration information in the output module-defined data type on a RSLogix 5000 system.

In addition, an output module is configured by a controller that establishes a connection as an owner; however, only one owner connection is allowed for output modules. If another controller attempts to establish an owner connection, the connection attempt is rejected.

Module-defined Data Type:AB:1797_OE8:I:0

Member Name	Type	Default Display Style	Description
Fault	DINT	Binary	Fault - Used for Input Data Validation0 = Valid Data1 = 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.
Alarms	INT	Binary	Alarm data for the DiagnosticStatus members 0 through 3 below. The remaining members are reserved.
DiagnosticStatus0 DiagnosticStatus1 DiagnosticStatus2 DiagnosticStatus3	BOOL	Decimal	These settings (0 through 3) represent module configuration and/or hardware errors.
Ch0Fault Ch1Fault Ch2Fault Ch3Fault Ch4Fault Ch5Fault Ch6Fault Ch7Fault	BOOL	Decimal	These members are used to determine if a fault has occurred on a channel.
