Module Data Types - 1794-OE4/B
The table below lists and describes module-defined data types for the 1794-IE8/B analog input 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. This may decrease performance with certain instructions.
