2-2 How Communication Takes Place and I/O Image Table Mapping
The amount of input data in the adapter’s input image for each I/O
module is based on the configuration of each I/O module done as
part of the 1769-ADN configuration. If an I/O module is configured to
have 0 words of input data, then it does not appear in the input image
of the 1769-ADN.
Adapter Status Words
The first two words (0 and 1) of the adapter input image contain the
adapter status. The adapter status consists of:
• I/O module data invalid bits - 1 status bit for each slot
• node address changed - 1 bit
