Is there a list of the system words used by the M340?

Specifically, I'm looking for a way to grab data such as the product name, version, and mac address from the PLC's for some reporting.
 
To find help on system bits and words open the help in Unity and select Index tab. %S and %SW are the first two entries

%SW14 - plc OS version
%SW15 - plc patch version
%SW16 - firmware version
%SW94 95 - program checksum

Thank you!

note: I wasn't utilizing a workstation with Unity installed (yet). I will now know where to look when I get it installed!
