Replacing The Cmr - Siemens LOGO! CMR2040 Operating Instructions Manual

Reaction after resetting to factory settings
After the reset, the RTU starts up again automatically. The remaining behavior depends on
the use of an optional SD card:
● Startup without SD card
– If you do not use an SD card, the CMR remains stopped without configuration data.
– The CMR is reachable locally via the following default IP address set in the factory
– The CMR starts up without configuration data.
● Startup with SD card
If an SD card is plugged in, the CMR searches the SD card for the configuration file
"default.cfg" which was deleted during the reset.
A configuration file "user.cfg" saved on the SD card by the user is not used.
If you turn off the CMR after the reset, and then start it up with an SD card plugged in with
a configuration file "default.cfg", the CMR uses the configuration file "default.cfg". See
also section Configuration (Page 77).

Replacing the CMR
If you need to replace the CMR, you can also use the SD card to transfer the configuration
data of the CMR stored there to the new device. Every change to the configuration data is
saved on a plugged in SD card.

the device (Page 35).
