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 converter 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 converter settings into the converter 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).
