2.2 Significance of the OUT Data (Data from the Master to the Encoder)

2.3 Significance of the IN Data (Data from Encoder to Master)

The IN as well as OUT data of the encoder are assigned 2-word addresses within the master (control). The absolute
position of these word addresses depends on the position of the encoder on the Interbus ring.

Please find below the value of the encoder data relating to the relative word address.
