Using HighĆdensity (16 point) I/O Modules
16-point I/O modules provide 16 input terminals or 16 output
terminals. 16-point I/O modules use a full word in the input or
output image table when they are addressed as a 2-slot I/O group
(Figure 3.5). Two 16-point modules (one input and one output) can
be used in a 2-slot I/O group.
