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

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. 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
How the "Permit overwriting of PROFINET device names of all assigned IO devices" option works
The IO controller (CPU) can overwrite the PROFINET device names of IO devices in the IO
system when the "Permit overwriting of PROFINET device names of all assigned IO devices"
option is enabled.
Multiple use IO systems can only be operated when this option is enabled. The IO controller
checks prior to overwriting if the type of the IO device matches the configured type.
If the option is not selected, the IO controller cannot overwrite the device names of the IO
devices. In this case, you must manually assign the PROFINET device name on the IO device if
the PROFINET device name changes in the configuration or when a device is replaced, or
delete the device names of the IO devices prior to an automatic commissioning.
