Once the PLC has been configured, if a device is replaced then the new device will be
automatically configured with the original device's properties, including the device name
and IP address.
For the discovery protocol to work, the replacement device must not have a device
name programmed, i.e. it must be blank or unused. If a device name exists in the
module and that name is different to the device name set in the network configuration
then the PLC will indicate a configuration error and will not enter data exchange with it.

Identification and Maintenance (I&M)
Identification and Maintenance (I&M) functions can be used to read and change various
information about devices, such as manufacturer, ordering information, serial number,
etc. This information can be used to assist the user in tracking the drive's life cycle
through commissioning/start-up, parameterization, diagnosis, repair, etc. SI-PROFINET
RT supports I&M0 to I&M4 inclusively; I&M0 is mandatory for all PROFINET devices,
I&M1 to I&M4 are optional.
Each I&M function returns specific information about the device and is explained in the
following tables.
