The Data Exchange operating mode is also available with firmware version 03 or
higher.
In this mode, the I/O module allows cyclic data exchange with another 750-652
I/O module configured in the same operating mode. Process data between
different fieldbus nodes can also be exchanged when integrated in different
fieldbus systems.

Figure 7: Internal structure

If two I/O modules are connected together in this mode, each I/O module
transmits the data bytes of the process output image cyclically to the I/O module
on the opposite side. Received data bytes of the process output image on the
opposite side are again represented as data bytes in the process image of the local
I/O module. The sequence of data bytes remains unchanged during transmission.
