Changing profibus address of mp270

Goodas Posts: 37 Rating: (0)	Hi I am trying to change the profibus address of a mp270. I edit the new address in "S7-transfer settings" on the deivce and then perform a reboot, however the address does not change. I alsountick the "panel is the only master on the bus" and this also comes back as ticked after reboot.There are 6 other HMI's on the network and have never had a problem with these. Am I missing something? Also wheni view the network over accessible nodes the device with existing address does not appear. I have changed this for an ET200 and this does appear on the network so wiring is o.k. Any ideas please.

After you have set the Profibus settings, did you after thentransfer a new project to the panel? or did you only make a reboot? Inthe control panel under "OP > Perisent Storage" you can try to use "Save Regestry" and "Save files" mybe this could be help. regards,

Just trying to change profibus address from 5 to 8but it still reverts back to the original setting after a REBOOT or power down. O.K I have just discovered the address only reverts back to the original when the profibus plug is plugged into the device. Anymore ideas.
