Title: Parse DNLoader File
Post by: petersrj on May 03, 2013, 03:47:25 PM

I need to create a report for several different PLCs, documenting the settings of various registers in the PLC.  One option that I want to explore is to parse the .DAT file created by DNLoader as this is standard for my customers to have this file.  I am not interested in the program portion of the file but more the C and V registers.  With that in mind, I have a few questions:

1.  Is there a better way to document settings inside of the PLC?

2.  Is there a document describing the .DAT file that might be available?

3.  I can find in the file where the V memory locations start.  Is the physical position fixed or does it vary with different versions of DNLoader.  If it is not fixed, I will need to look for the header of the section.

Thank you for your help.

We don't have any specifications for DNLoader, but the format is not complicated. I sent you a PM of the relevant function. Let me know if I can explain anything.
