Numbered parameters in the range of 31-5000 can be added to the "linuxcnc.var" file (it should be located in your config dir). Then the values of those numbered parameters you've added to that file will be saved and remembered when Linuxcnc exits and is restarted. However, if Linuxcnc does not exit properly the var file will not get updated and it is possible that the file can become corrupted and all of your variable settings will be lost. This also includes loosing your machine coordinate settings as well. So it is wise to back up that file occasionally.

You can't. At least not directly. What exactly are you trying to do? Perhaps there is a simpler method.

I just want to save the workpiece counter, and the work hour counter state on every exit from Linuxcnc.

This is a little kludgy, but the simplest way to get a value from a hal pin into a g-code variable in Linuxcnc is to use one of the motion.analog-in-nn halpins.
For example in hal you would connect "motion.analog-in-00" to your hal pin for your timer. Then in your g-code file, when you want to get that value and save it to varaible #3000, insert this.
Then you can add 3000 to the list of numbered parameters in your linuxcnc.var file to make it be remembered the next time Linuxcnc is started

What do you think about these custom modules?
Can I use for saving some variables, and working hour?
Does anybody used these?
wiki.linuxcnc.org/cgi-bin/wiki.pl?Contri...ents#Parameter_Saver
or:
github.com/torvn77/LinuxCNC-Work-Counter
Unfortunately i never install a custom linuxcnc modules.
Is these a documentation step by step how to compile it in linuxcnc project?

Does your part counter originate in G-code or in HAL?
I can think of different ways to do this for each situation.

The counter is in HAL code. A dont know how can i count the parts from G code.
Is there a documentation how to install custom C HAL module. For me, will be very useful the param saver module. What you think about? Can i use this for general purposes, i want just to save some parameters that changes over time.
Thanks Attila.

Yes in the HAL section of the documents.
