Permit Overwriting Of Profinet Device Name - Siemens SIMATIC ET 200AL System Manual

Requirements
● The topology of the PROFINET IO system with the respective IO devices must be
configured.
By configuring the topology, the neighbor relationships of all the PROFINET devices
located in the PROFINET IO system are announced to the PROFINET IO system or the
IO controller. From the neighbor relationships specified by the set topology and the actual
neighbor relationships established by the real PROFINET devices, the IO controller can
identify the replaced IO device without a name and assign to it the configured name and
the IP address and then again list it in the user data traffic.
● The affected IO devices in the automation system must support device replacement
without exchangeable medium.
If the individual IO devices in the automation system do not support device replacement
without exchangeable medium, a corresponding alarm is output for the IO device.
Note
Use only new IO devices as replacements or restore configured IO devices to their
delivery state.
Activating/deactivating device replacement without exchangeable medium
The "Device replacement without exchangeable medium" function is activated in the
IO controller by default.
To deactivate device replacement without exchangeable medium, follow these steps:
1. In the device or network view of the STEP 7, select the PROFINET interface in the
corresponding IO controller.
2. In the interface properties under "Advanced options > Interface options", clear the
"Support device replacement without exchangeable medium" check box.
To reactivate device replacement without exchangeable medium, you must select the
"Support device replacement without exchangeable medium" check box again.

Permit overwriting of PROFINET device name

With the option "Permit overwriting of PROFINET device names of all assigned IO devices",
you can overwrite PROFINET device names of IO devices during startup of the CPU. This
option reduces the effort during automatic commissioning, for example, when replacing a
device.
Requirements
● IO controller supports the "Permit overwriting of device names of all assigned IO devices"
option, for example CPU 1215C DC/DC/DC as of firmware version 4.0
