I have a notebook running RSLogix500 v6.3 that I use to add a few rungs and change a few data table values to a program. After saving the program, I copied it over to my desktop pc running RSLogix500 v7.0. When I open this program with the 7.0, the new rungs are still there but the data table value revert back to their original values!! Anyone seen this? If I use the notebook to open the file I copied over to the desktop via our local network, the values are still there! I recently upgraded the desktop pc to 7.0 but has never had this problem before with some of the older versions.
