120 POINT I/O Module Data
The 1734D-IA8XOW8 module produces one byte of input data (scanner Rx)
status) It consumes one byte of output data (scanner Tx).
The 1734D-IA16 module produces two bytes of input data (scanner Rx). It
does not consume output data (scanner Tx).
For 1734D-IB16 modules, I/O messages are sent to (consumed) and received
from (produced) the POINTBlock I/O modules. These messages are mapped
into the processor’s memory. This module produces two bytes of input data
(scanner Rx) and does not consume output data (scanner TX).
