3.2.9Diagnosis
The slave diagnosis of the bus controller comprises of a 6 byte standard diagnosis, 9 byte identification based diagnosis, 7 byte device status and up to 42 byte channel based diagnosis.
In the reply telegram of the diagnosis selection, in addition to the standard diagnosis at least the identification based diagnosis and the device status are transmitted. This could be followed by up to 14 channel based diagnosis messages (3 byte per message).

3.2.9.2PROFIBUS-DP master address
The PROFIBUS-DP master address is located in byte 3 of the slave diagnosis and contains the master address parameterised by the station and to which it has write and read access.
3.2.9.3Manufacturer identification
The manufacturer identification is located in byte 4 and 5 and contains a 16 bit code, intended for the identification of the device or the device class.
3.2.9.4Identification based diagnosis
The identification based diagnosis comprises of a bit field containing a bit information for each connected module. The individual bit provides information about the current operating status. A 0 means no fault, a 1 indicates a faulty module status. The bus controller can be fitted with up to 63 modules, so that the identification based diagnosis including header covers 9 bytes from byte 6 to byte 14.
