Module Data Types 1794-OW8

The table below lists and describes the module-defined data types for the 1794-OW8 Digital Output 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 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:1794_DO:I:0
This module-defined data type does not apply to modules having Rack Optimization selected for the Comm Format and does not appear among the Module Tags in the RSLogix software.

Safe state data.
safe state
The condition that an output module maintains in the event of a network communication error, or when the controller enters the program mode. When either of these situations occur, the outputs automatically switch to the configured state (for digitals) or to the value (for analogs).
