An “output” is a value coming into the 905G via the fieldbus. An input is a value going out from the 905G via the fieldbus.

    Where a 905G is being used without a host device as a repeater or data-concentrator, it can be configured as “Repeater-only”. This allows the RS232/485 port to be used for on-line diagnostics. If the unit is a 905U-G-MD1, the “Repeater-only” configuration also allows this module to connect to 105S serial I/O modules.

A Write mapping is a message sending a block of values to another 905G. A Read mapping from 905G#2 to 905G#3 could be the same as a Write mapping from 905G#3 to 905G#2 (that is, in the reverse direction) - except the Read mapping is initiated from #2 and the Write mapping is initiated from #3.
