The positions POS14 and POS21 are not relevant in relation to the
exchange of data. They do not appear in the list. If a byte, e.g. E11, is not
used completely, the bus coupler pads the remaining bits of the byte with
zeros.
Overview of the breakdown of the process image in the bus coupler:

The base addresses E0 and A0 listed here are relative addresses or
addresses in the bus coupler. Depending on the higher-level field bus, the
addresses may be placed in a freely chosen position in the controller's
process image by the bus master. The master's configuration software
