Hello Omar; So you have 2 errors, one with the old configuration and a missing slve, the other when you ownload the new configuration (but with the salve removed). Do I understand the situation correctly? What error messages do you have in the diagnostic buffer of the CPU? You should at least have messages corresponding to the new configuration problem. Load them up here so we can look at them, if you have difficulty understanding them. Use the Save As..Text button in the diagnostic buffer to save the messages. Now: do you have a RAM or an EEprom card in your CPU, as load memory. That could have a bearing on the way the CPU reacts to a hardware download. An EEprom card requires an "Download User Program to memory card" instruction to load the new configuration.

You could try to disable the slave in the original configuration, using SFC12. This removes the slave from the polling list in the Profibus configuration, and would temporaily solve your problem, I think. See the following FAQ:
How do
you switch off (decouple) a slave without causing an error entry to appear in
