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.
