12.2 Process Data Architecture for Modbus-TCP
With some I/O modules, the structure of the process data is fieldbus specific.
Modbus-TCP process image uses a word structure (with word alignment). The
internal mapping method for data greater than one byte conforms to the Intel
format.
The following section describes the process image for various
WAGO-I/O-SYSTEM 750 XTR I/O modules with Modbus-TCP.
Equipment damage due to incorrect address!
Depending on the specific position of an I/O module in the fieldbus node, the
process data of all previous byte or bit-oriented modules must be taken into
account to determine its location in the process data map.
