Corrective maintenance
10.1 Overview of replacing converter components
Device replacement without removable storage medium - only for communication via PROFINET
If you have created a topology in your control, you can use environment detection to replace
a defective inverter with a new device of the same type and with the same software release.
Recommissioning is not required in this case.
You can either load the inverter settings into the inverter using the memory card or – if you
are using a SIMATIC S7 controller with DriveES – using DriveES.
Details of the device replacement without removable storage medium can be found in the
Profinet system description (http://support.automation.siemens.com/WW/view/en/19292127).
