Diag.Ext_Diag
This bit is set by the DP slave. It indicates that a diagnostic entry exists in
the slave-specific diagnostic area (Ext_Diag_Data) if the bit is set to one. If
the bit is set to zero, a status message can exist in the slave-specific
diagnostic area (Ext_Diag_Data). The meaning of this status message
depends on the application and will not be fixed in this specification.
Diag.Cfg_Fault
This bit is set by the DP slave as soon as the last received configuration
data from the DP master are different from those determined by the DP
slave.
Diag.Station_Not_Ready
This bit is set by the DP slave if the DP slave is not yet ready for data
transfer.
Diag.Station_Non_Existent
This bit is set by the DP master if the respective DP slave can not be
reached over the line. If this bit is set, the diagnostic bits contain the state
of the last diagnostic message or the initial value. The DP slave sets this bit
to zero.
Diag.Deactivated
This bit is set by the DP master as soon as the DP slave has been marked
inactive within the DP slave parameter set and has been removed from
cyclic processing. The DP slave always sets this bit to zero.
