Parameter assignment/addressing
3.2 Device name and IP address
Note
The icon "Ready for assignment" appears when a MAC address exists and matching device
data was found, but no PROFINET device name was found online.
You can update the data of the detected devices again via their MAC addresses at any time.
To do this, you specify the MAC address and the status of the device is displayed
immediately without having to re-detect the device.
Procedure (step 2)
All PROFINET device names configured offline will be assigned to the devices available
online in a bulk operation.
1. Click the "Assign now" button.
Note
The bulk operation cannot be reversed. A message to this effect appears in a dialog
window.
2. Click "Start" in the dialog window to start the assignment of the PROFINET device
names.
Result
The PROFINET device names configured offline will be assigned to the devices available
online. This relates to devices in whose row the check box under "Assign device" is selected,
that have a MAC address and have the status "Ready for assignment".
Importing and exporting data
Using the import and export button, you can import or export the data of the I/O
communication table for the online assignment:
● When you export, the currently displayed data of the table is exported to a CSV file. Using
the filter function of the table, you can select which data will be exported.
● When you import, the data of the CSV file is written to the table. If there are conflicts with
values already existing in the table, you can decide whether the data should be
overwritten or whether the import needs to be stopped.
