I have an 3m control that has a dead backup battery,I ordered the battery. I have never owned siemens control before.I have a floppy with files that look to be machine data,and parameters.I cant open those files with any program on a windows xp desktop I am using. I suppose I will be connecting that old pc to this control shortly. I also have one of those dnc boxes that I use to load programs into my fanuc control via rs232. I have read a couple posts that mention a procedure to load this data? I am reading through the manuals I have and some I got from siemens website but It isnt obvious to me how this is going to go yet. Any Siemens Gurus have any knowledge they want to share?
