Description of the DP Functions, Data, and Error Codes
DP Base Programming Interface for CP 5613/CP 5614
C79000-G8976-C108-01
103
Note 4
If the event DP_SLAVE_ENTER or DP_SLAVE_EXIT is signaled in consecutive
DP_enable_event confirmations (with no DP_SLAVE_EXIT or
DP_SLAVE_ENTER in the meantime), this means the following:
Multiple DP_SLAVE_ENTER: The slave changed to the NOT READY state
and back to the READY state.
Multiple DP_SLAVE_EXIT: The slave changed to the READY state and then
back to the NOT READY state.
Note 5
If the slave is in the NOT_READY state and the DP_DIAG_ALARM selector is
activated, the event is signaled only when the slave signals Diag.Prm_Fault,
Diag.Cfg_Fault or Diag.Ext_Diag in its diagnostic frame (for more information on
the formats, see Section 4.6).
Note 6
If the DP master is not in the state to be monitored (mst_state) at the point when
DP_enable_event is called with the DP_MST_STATE selector, the event is
triggered immediately.
Syntax
