Diagnostic messages
Diagnostics
By requesting diagnostics data, the DP master checks in the startup phase whether the DP
slave is available and ready for parameterization. The diagnostics data communicated by the
DP slave consists of a diagnostics data section defined in EN 50170, and specific DP slave
diagnostic information. The DP slave informs the DP master of its operating state
(PROFIBUS DP-related) via the diagnostics data, and of the cause for the diagnostic
message in a diagnostics case.
