How Communication Takes Place and I/O Image Table Mapping

Publication 17946.5.5 - October 1996

For example, a 16 point discrete input module will have up to 2 read
words and 1 write word.

Check the I/O map for each module for the exact mapping.

Output data is received by the adapter in the order of the installed
I/O modules. The Output data for Slot 0 is received first, followed
by the Output data for Slot 1, and so on up to slot 7.

The first word of input data sent by the adapter is the Adapter Status
Word. This is followed by the input data from each slot, in the order
of the installed I/O modules. The Input data from Slot 0 is first after
the status word, followed by Input data from Slot 2, and so on up to
slot 7.
