your module.
I/O messages are sent to (consumed) and received from (produced)
the POINT I/O modules. These messages are mapped into the
processor’s or scanner’s memory. This POINT I/O input module
produces 1 or 2 bytes of input data based on which produced
assembly is selected. The default setup is 2 bytes. It does not
consume I/O data (scanner Tx).
