Survey of the Entire Range of Diagnose
Data Registers
If the user is well acquainted with the PROFIBUS-DP standard and its DPV1
extensions, he can freely access the user data. The first 6 bytes must never be
altered, as they will be overwritten with certain values by the PROFIBUS controller.
Starting from the 7th byte, the external diagnose data can be entered according to
the standard. Thus it will also be possible to transmit identification and channel-
related diagnose telegrams.
The length that is defined in length register 1m140 must also contain all bytes, the 6
DP standard bytes included.
Please do also mind the correct sequence of data input here as well, i.e. the length
must be entered first; only after this, the data can be altered.
Writing into the length register will always overwrite the 7th byte of the diagnose
telegram automatically.
