IP address assignment when replacing IO devices with exchangeable mediumPG
The following is contained on the memory card of the programmable logic controller:
•
On the IO controller: Device name and IP address
• On the IO device: Device name
When you remove the memory card from a PROFINET device and insert it in another
PROFINET device with exchangeable medium (e.g., ET 200S), device-specific information and
the device name are loaded to the device.
If an IO device has to be replaced in its entirety due to a device or module defect, the IO
controller automatically assigns parameters and configures the replaced device or module.
The cyclic exchange of user data is then restarted. In addition to this, before the power ON of
the IO device, the memory card with the valid name must be removed from the faulty IO
device and added to the replaced device.
In the event of an error in the PROFINET device, the memory card allows you to replace a
module without a programming device/PC. You can also transfer the device data directly from
the programming device/PC to the memory card.
Procedure: Changing the device name using properties of the PROFINET interface
You can change the PROFINET name via the properties of the PROFINET interface. This is
useful when the PROFINET device has not received its previous name from the automatic
generation, for example, in the case of a migration.
1.
In the network or device view of the STEP 7 hardware and network editor, select the
PROFINET interface of a PROFINET device.
2. In the Inspector window, go to "Ethernet addresses" in the PROFINET area.
3. Clear the "Generate PROFINET device name automatically" check box.
4. Enter the new PROFINET device name in the relevant field.
