Section 8: PROFIBUS DP-V0 diagnostics

Until the PMINT is parameterized and configured by the PROFIBUS
master, a request for diagnostics by the master will result in
the PMINT returning only the mandatory 6-byte PROFIBUS
diagnostics information .
Once successfully parameterized and configured, the PMINT will
append additional device-related diagnostics information to the
mandatory PROFIBUS diagnostics information, as described in
Table 12 . The diagnostics user data, starting at bit 24, is also
described in the GSD file (Appendix A) .
N otee: Configuration is required before this additional information can be
included because the user-defined "Data Object X invalid" bits are defined
by and dependent upon the cyclic data exchange monitoring format selected .
Any change in the PMINT diagnostic information is signaled to the PROFIBUS
master when the PMINT returns a high priority cyclic data exchange .
