Operation Log Format - Omron FZ4 Series User Manual

Operation log format

The operation log is stored with a file indicating the date and time as follows in the directory
●
specified as the save destination.
YYYY-MM-DD_HH-MM-SS.log (Example: 2012-08-20_12-00-00.log)
The date and time shown in the file name is the date and time at which the log file was
●
created.
The maximum size for a log file is about 100 KB. If a log file is larger than 100 KB, from the
●
first record over 100 KB, the log is written into a new file.
When the log is stopped, then started again, a new log file is created.
●
Also during operation log execution, if the save destination directory setting is changed, at
●
that point in time, a new log file is created in the new save destination.
The log file character code is UTF-8 with BOM.
●
Basically, information is saved when the API (application program interface) is executed. The
●
information for one API information is written into the log file as one record.
The format for each record written into the log file is as follows. The four data items of the
execution date and time, user name, input information, and output information is expressed
delimited with semicolons. At the end of the record, line feed (CR+LF) is entered.
(Execution date and time); (user name); (input information); (output information) [LF+CR]
