"5".
All PROFIBUS DP slaves are listed here, for which actual value data can be retrieved. It
also provides the possibility of sharing data via slave-to-slave communication within the
same drive device.
8. The "I/O address" column displays the start address for every drive object.
Select the start address of the data of the drive object to be read. In the example, "268" is
proposed.
If the complete data of the publisher is not to be read, set this using the "Length" column.
Alternatively, you can shift the start address of the access, so that the required data can
be read out from the center section of the telegram component of the drive object.
