How Communication Takes Place and I/O Image Table Mapping 2-5
The following sections, as referenced above, give the input and
output data definitions for each Compact I/O module type. Their
mapping into the adapter’s input and output images are dependent on
their slot number and configured input and output sizes (as defined in
the I/O Structure section on page 2-1).
1769-IA8I Individually
Isolated 120V AC Input
Module (8 Point)
Input Data
For each 1769-IA8I input module, input data word 0 contains the
current state of the field input points. Bits 8 to 15 are not used.
1769-IA16 120V ac Input
Module (16 Point)
Input Data
For each 1769-IA16 input module, input data word 0 contains the
current state of the field input points.
