Addressing Of I/O Modules; Table 32: Data Width For I/O Modules - WAGO -I/O-SYSTEM 750 Manual

92 Function Description
7.3.2.1

Addressing of I/O Modules

Addressing first references complex modules (modules that occupy several
bytes) in accordance with their physical order downstream of the fieldbus
coupler/controller; i.e., they occupy addresses starting from word 0.
Following these is the data for the remaining modules, compiled in bytes
(modules that occupy less than one byte). In this process, byte by byte is filled
with this data in the physical order. As soon a complete byte is occupied by the
bit oriented modules, the process begins automatically with the next byte.
Hardware changes can result in changes of the process image!
I f the hardware configuration is changed and/or expanded; this may result in a
new process image structure. In this case, the process data addresses also
change. If adding modules, the process data of all previous modules has to be
taken into account.
Observe process data quantity!
For the number of input and output bits or bytes of the individual IO modules
please refer to the corresponding description of the IO modules.
