Post the program you are trying to download.
The .rss file (zip it first)

This is an old issue that I've seen quite a few times before...

7728 - RSLogix 500 - Program is incompatible with processor
Access Level: TechConnect

Basically, the program running in the processor can become a little corrupted. To knock it back into shape the first thing to try is a simple power cycle of the controller and then attempt a Download.

If that doesn't work, then try temporarily changing the "Processor Type" under "Controller Properties" to a different processor. Perform a "Verify Project" for the entire project and it will shuffle the Data Table file around. Then change the "Processor Type" back to the original and perform another "Verify Project". This will reshuffle the Data Table files back into shape as they should be. Then attempt a Download again and hopefully it should work.

This used to be an issue with RSLogix500 v7.0, what version are you using?
