When using this configuration the PLC bytes In and PLC bytes Out are limited to 256 each.
The PLC bytes In and Out data areas is mapped so that all data bits (bit points) are placed first (beginning
at offset zero) then followed by the data words (word points). See chapter: Fieldbus Interface for more
information on how the input and outputs are accessed by the PLC.
Since this fieldbus type does not handle Process Data directly it is not possible to connect a Reporter to it.
With parameters set as in the above example the input and output areas is mapped as below:
