Structure of Process Data for the I/O Modules

The process image for the I/O modules on the internal data bus is built up word-
by-word in the controller (with word alignment). The internal mapping method for
data greater than one byte conforms to Intel formats.
The following section describes the representation for WAGO-I/O SYSTEM 750
(750 and 753 Series) I/O modules in the process image, as well as the
configuration of the process values.
Equipment damage due to incorrect address!
To prevent any damage to the device in the field you must always take the
process data for all previous byte or bit-oriented I/O modules into account when
addressing an I/O module at any position in the fieldbus node.
No direct access from fieldbus to the process image for I/O modules!
Any data that is required from the I/O module process image must be explicitly
mapped in the CODESYS program to the data in the fieldbus process image and
vice versa! Direct access is not possible!
