6.2 Example for an Input Process Image

The following figure is an example of an input process image.
The configuration comprises 16 digital and 8 analog inputs.
The input process image thus has a data length of 16 bytes for the analog
modules and 2 bytes for the digital modules, i.e 18 bytes in total.
