Diagnosis data of the SP-PROFIBUS-DP module
The SP-PROFIBUS-DP module makes diagnostic data available via PROFIBUS-Standard-DP-V0
diagnosis:
• Standard diagnosis (6 bytes)
• Device-related diagnosis State messages or manufacturer-specific messages
Each module has a unique module ID. The gateway determines the manufacturer-specific di-
agnosis number based on this ID. In this way, module-specific diagnosis texts can be read out
of the GSD. The following table shows the content of the diagnosis messages:

which do not, however, represent physical slots. For this reason, all messa-
ges should be assigned to Slot 0 (the gateway itself).
