Selecting and enabling the debug mode of Axxon PSIM software

Debug mode is a special operation mode when the Debug Window is open, and is designed for analyzing the progress of Axxon PSIM software operation and for prompt debugging in case errors occur. Log files are created in this mode - they are stored on the disk for a specific time period. 

Enabling debug mode

By default, debug mode is disabled. To enable debug mode, do the following:

1. Shut down Axxon PSIM software.
2. Start the Tweaki.exe utility (see the Starting and shutting-down the Tweaki.exe utility)
3. Select the Axxon PSIM node in the tree on the left side of the utility dialog box.
4. Change the parameter Debug Mode from None to Debug 1, Debug 2, Debug 3 or Debug 4 (see The Settings panel of the Windows section).
5. Click the OK button.
6. Start Axxon PSIM system.
   The Debug window item will appear in the Axxon PSIM main control menu.
   
7. Select Debug window in the main control menu to open the Debug window. The selected item will be marked with a tick.
   

To hide the Debug window, select the Debug window item in the menu once more.

Configuring log keeping 

One can set log keeping parameters both on the Axxon PSIM setting panel in the Tweaki.exe utility (see The Settings panel of the psim.section) and using some registry keys:

1. The Time of log keeping (hours) parameter means the same as DebugTime registry key. It specifies the number of hours for keeping log files. 48 hours by default.
   
2. The Maximum size (MB) parameter means the same as DebugSize registry key. It specifies the number of megabytes provided for log. 100 MB by default.
   
3. The DebugZipDays registry key enables the logs archiving in the .gz format and specifies the time period for their keeping. 2 days by default.
   

Log files are rewritten when one of these parameters is at its maximum. 

Find more about registry keys in Registry keys reference guide.

Example.

The Time of log keeping (hours) is 720 hours (1 month) and the Maximum size (MB) is 100 MB.  

One week later the size of log file is 100 MB. It starts being rewritten though the log is kept less than it was specified. 

And if DebugZipDays has the value equal to the time period in days to keep logs, then logs are not rewritten - they are archived in the *.gz format and are kept for so long as it was specified in DebugZipDays parameter.
