When replacing an existing CPSN-MCB271 on the system with a new device, there is a function to inherit the device name.
[Device name inherit conditions]
- Same model CPSN-MCB271
- All I/O modules connected to CPSN-MCB271 are the same model.
- All I/O modules connect to the same slot on the CPSN-MCB271.
If the conditions are not met, the device name cannot be inherited.
If you are unable to inherit the device name, please refer to [Example
where device name cannot be inherited: ].
1. Disconnect the old CPSN-MCB271 from the network.
2. Connect the new CPSN-MCB271 to the network.
3. Start the CONTEC Device Utility and press the "Reload" button.
The new CPSN-MCB271 and the old CPSN-MCB271 will be displayed under the "NET" tree as shown below.
The old CPSN-MCB271 under the
"NET" tree is determined to be not connected to the network
and becomes an 
icon.
The I/O module below the old CPSN-MCB271 will also become an
icon.
A new CPSN-MCB271 will be added
and registered under the "NET" tree and become an 
icon.
The newly added I/O module under CPSN-MCB271 will be in the
"(New) device type" state and will be an icon.
Set the IP Address of the new CPSN-MCB271 to the same as the IP Address of the old CPSN-MCB271 and press the "Save" button.
If the CONTEC Device Utility recognizes that the IP Address and I/O module configuration are the same, the "Setting Updated" message will be displayed.
3. Click the "OK" button on the "Setting Updated" message.
The old CPSN-MCB271 and I/O modules will be deleted from the "NET" tree.
The device name under the old CPSN-MCB271 will be reflected in the I/O module under the new CPSN-MCB271. (For the example below: "AIO000" and "DIO000")
- There are more I/O modules connected to the new CPSN-MCB271 than the old CPSN-MCB271
- There are fewer I/O modules connected to the new CPSN-MCB271 than the old CPSN-MCB271
- The I/O modules connected to the old CPSN-MCB271 and the new CPSN-MCB271 are the same, but they are connected to different slots on the CPSN-MCB271
- The IP address set on another Ethernet device
was set to the "IP Address" setting of the new CPSN-MCB271.

is displayed IP Address is invalid message".
