hi guys i have a same issue and look for solution every where i bought a L24ER for my school project from ebay and did not touch it for a while and then tried to accomplish my project so i went online with plc but before that rs5k asked me to firmware update due to existing version 1.003 on plc so no problem so far i picked version 20 every thing seems to be perfect but after update gets done right before it shows green note as update finished successfully i get this message "Error #11001: Unknown General Status error code received" i did update on many ab plc's never had such a thing so after that i tried all version from 20 to 29 whatever firmware version Allen Bradley made so far but no luck yet i was wondered if any one had same situation that can help me any help is highly appreciated
