10 Communicate With Your Module
For example, a 16 point discrete input module will have up to 2 read words and 1
write word.
Refer to each module user manual I/O map for the exact mapping.
Polled I/O Structure
The first word of output data received by the adapter is the Adapter Status Word.
Output data is received by the adapter in the order of the installed I/O modules.
The Output data for Slot 1 is received first, followed by the Output data for
Slot 2, and so on up to slot 8. All bits in the output status word are reserved.
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 1 is first after the status word, followed by
Input data from Slot 2, and so on up to slot 8.
Adapter Input Status Word
The input status word consists of:
• I/O module fault bits — 1 status bit for each slot
