Module Data Types 1794-OB16
The table below lists and describes the module-defined data types for the 1794-OB16 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.
