5.2 Process Data Architecture for MODBUS/TCP

With some I/O modules, the structure of the process data is fieldbus specific.

In the case of a coupler/controller with MODBUS/TCP, the process image
uses a word structure (with word alignment). The internal mapping method for
data greater than one byte conforms to the Intel format.
