Exchanging the BusAdapter or interface of the distributed I/O

The device name of the distributed I/O device is saved at the following locations when
transferring the device name to the distributed I/O:
● In the BusAdapter
● In the interface of the distributed I/O device (e.g. interface module or I/O device itself)
Note
Replacing a BusAdapter (removing/inserting)
Removing/inserting the BusAdapter under voltage is prohibited.
Device replacement without transfer of topological configuration
The following scenarios are the result of saving the device name on the BusAdapter and in the
interface when exchanging the two components:
BusAdapter non-program‐
med
(without device name)
BusAdapter with device
name
Note
Restoring the factory settings
Resetting to factory settings deletes the device name in the interface and in the BusAdapter.
