AutoIdLastLogEntryEvent
This is an event for the last log entry. A "LastLogEntryEvent" is generated for every event
that was made in the log. The prerequisite is that the "Parallel" or "Diagnostics" option is set
in the WBM.
Note that the log is assigned to the communications module and not to a read point. Even if
entries for read points are made in the log, log entries are always made by the
communications module. The associated "LastLogEntryEvents" are always generated by the
communications module. The OPC UA read points only serve as transmitters of events to
OPC UA clients. This has the consequence that every read point transmits all
"LastLogEntryEvents", even those that relate to other read points. In the WBM, you can
define the read points via which the "LastLogEntryEvents" should be transmitted.
In addition to the inherited properties of "BaseEvent", a "LastLogEntryEvent" also contains
the following Property:
●
DeviceName
Table 10- 41 DeviceName
Data type
String
Description
Name of the communications module that made the log entry
and generated the Event.
This Property is inherited from "AutoIdDiagnosisEvent". The
inherited standard property "SourceName" of "BaseEvent" con-
tains the BrowseName of the read point via which the event was
transmitted.
Possible values
Example:
SIMATIC_RF188C (192.168.0.254)
The text of the log entry is in the "Message" Property inherited by the "BaseEvent".
