Thank you for your quick answer,

yes I am using Comfort P 1200 and that was exactly what I was afraid of .

My problem is,
I have the same program for few almost the same machines, in that way if I make some changes I only need to do it in one program and load it on all machines. 

Do you have any idea how to know which alarm came from which machine if I load same program on different machines (all alarms would then be in one alarm log file - shared folder).

I see two options:
- Going through all allarms and insert machine name in alarm text (but I can't change/insert machine name in system alarms etc.)

- There is ofcourse an option to change alarm log path every time before loading the program to the machine, but I would like to avoid this option, because it's an eazy way to make a mistake and forget to change it before loading the HMI program.

If you remember any other way please let me know.
Best regards
Tilen
