2.6.4 Entries in the Log File of an Ethernet Module
The use of the log file requires the installation of an Ethernet module ( RUB IE or RUB PM ).
As it is shown in the tables of chapters:
•
‘ Word Clock Monitoring ’ – ‘ Consequences of Errors’ ,
•
‘ Real-Time Reference Monitoring ’ – ‘ The Individual Errors and C onsequences of Errors’ ,
•
‘ Self Test ’,
every error can produce an entry in the log file if the corresponding ‘ disable ’ checkbox has not
been checked.
Additional entries can be produced triggered by the following events:
•
manual or automatic changeover,
•
error reset – pressing key FAIL (or any key assigned with the ‘ Reset All ’ function) or
clicking the ‘ Error Reset ‘ button at the Switcher page of any configuration tool.
Open the log file clicking on /public/system.log at the System page of an Ethernet module.
Example: (SW 2:1) identifies the module which sent this entry:
SW module located at frame address 2 at slot 1 .
[22/Apr/2013 11:03:33] (SW 2:1) Event: CLOCK IN1 signal 3 loss
[22/Apr/2013 11:03:33] (SW 2:1) Event: System automatic changeover
[22/Apr/2013 11:03:33] (SW 2:1) Event: CLOCK IN1 signal 2 loss
[22/Apr/2013 11:03:33] (SW 2:1) Event: CLOCK IN1 signal 1 loss
[22/Apr/2013 11:03:33] (SW 2:1) Event: CLOCK IN1 signal 4 loss
[22/Apr/2013 11:03:37] (SW 2:1) Event: System manual changeover
[22/Apr/2013 11:03:41] (SW 2:1) Event: System error reset
The Ethernet module adds a time stamp (time & date) = time of its internal clock
when it receives the entry.
If SW receives real-time reference signals and no other module of the system sends the
‘ Reference ’ telegram, this telegram should be sent from SW module (s ee chapter ‘” Link“:
Communication between Modules ’ ). This telegram sets and synchronizes the internal clock of
the Ethernet module. The time stamps of each entry now correspond to the UTC time & date of
the event.
