3.1.9Diagnosis
The slave diagnosis of the bus coupler now comprises of a 6 byte standard diagnosis, a 9 byte identification diagnosis, a 7 byte device status and an up to 42 byte channel based diagnosis.
In the reply telegram of the diagnosis selection the identification based diagnosis and the device status are transmitted together with the standard diagnosis. This can be followed by up to 14 channel based diagnosis messages (3 byte per message).

3.1.9.1Station status 1 to 3
see EN 50170
3.1.9.2PROFIBUS-DP master address
The PROFIBUS-DP master address is located in byte 3 of the slave diagnosis and includes the address of the master which has parameterised the station and which has read and write access.
3.1.9.3Manufacturer‘s identification
The manufacturer’s identification is located in byte 4 and 5 and includes a 16 bit code, which serves for the identification of the device or the device class.
3.1.9.4Identification based diagnosis
The identification based diagnosis comprises of a bit field, which contains one bit of information for each connected module. The individual bit provides evidence about the current operating status. A 0 means no fault, a 1 indicates a faulty module condition. The bus coupler can be equipped with up to 63 modules, so that the identification based diagnosis including the header covers 9 bytes from byte 6 to byte 14.
