18.2 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 and 753 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.

The structure of the process data mapping is identical for the PFC process image

of the programmable fieldbus controller.
