Hello all! I am in need of the V21 firmware upgrade for the L33ER compact logix processor. I recently upgraded to V21 Studio 5000 and the program I was working with had to be converted to V21 in order to update it. I went to download it into the L33 and it prompted the firmware needed to be upgraded. I have looked on Allen Bradleys knowledge base and there is no version 21 upgrade. Does anyone have any tips or ways of assissting me?
