6.9.7 Error Log
For troubleshooting purposes the FemtoFiber
®
pro firmware maintains a log file, collecting all important
events happening during operation. It contains information about the initialization process after system
power up as well as a list of errors and warnings, eventually occurring later. The log file is reset upon sys-
tem boot and only contains information about events that happened since laser power on time.
In order to have a look at this log file use the command
ffpro.printlog() (command, 1 optional parameter, no result value)
Print log messages since last system boot,
parameter: (optional) filter type: "all","err","warn" or "alert"
Example:
>>> ffpro.printlog(“all”)
...
>>>
will print out the complete content of the log file to the console. By specifying a different filter name, the
output can be reduced to only contain information of the desired priority.
All log file entry have a certain priority level:
The command ffpro.printlog() without any parameters will report only warnings and alerts. The most
important entries, i.e. all warnings and alerts, are additionally collected in a persistent log file which is not
deleted when the system is switched OFF. This service log file will remain until it is reset by a T
OPTICA service
engineer.
In order to print out it's contents use the command
ffpro.printplog() (command, no parameter, no result value)
Print service log messages being permanently stored in the internal flash memory.
The command does not need any parameters:
>>> ffpro.printplog()
...
>>>
The result of the commands ffpro.printlog(“all”) and ffpro.printplog() are also available on the lasers
webpage and are also a very valuable source of information for the T
OPTICA service staff in case of a
problem.
Filter Importance Description
err low “errors” are the most unimportant entries. They only report minor failures
during the operation of the laser and include, e.g. mistakes such as using
a command with a wrong parameter or trying to switch ON the emission
without having closed the interlock circuit. Errors are supposed to have
no impact on the system health.
warn high “warnings” produced by the FemtoFiber
®
pro firmware report more
important events or problems. If, e.g. the FemtoFiber
®
pro Control Unit is
switched ON without a laser head being connected, the firmware will
detect this problem during initialization and report it with several warn-
ings. Opening the interlock circuit while the emission is switched ON will
switch OFF the laser emission and leave a warning in the log file.
alert highest “alerts” report the most severe problems. If you find some alerts on the
log file, please consult the T
OPTICA Photonics AG service staff.
