Process Data Architecture for EtherNet/IP
With some I/O modules, the structure of the process data is fieldbus specific.
In the case of a fieldbus controller with EtherNet/IP, 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.
The following section describes the process image for various WAGO-I/O-
SYSTEM 750 and 753 I/O modules when using a fieldbus controller with
EtherNet/IP.
For the PFC process image of the programmable fieldbus controller is the
structure of the process data mapping identical.

NOTICE
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.
