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.
