Nudge> The firmware version in the SLC5/05 is "most likely" too new for your version of RSLogix500. So either upgrade your version, or use "someone elses", that is at a "newer" version, to do your work...or downgrade the firmware to an "older" version that will work with yours.
I think we all know the obvious choice.
