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.

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
