Attention:
For Interbus S the data is written in Motorola format (high Byte first). In connection with other fieldbus systems the Bytes in the data word are changed.
Attention:
The control byte allows the changing of the registers of the module. It must always be 0 in order to avoid a change in the registers. A wrong mapping can change the function of the module!
