Corrected from:Controller c520 from V1.5
Controller c550 from V1.5
Controller c750 from V1.5
Response of the new version:
When replacing devices, the IP address stored on the SD card is restored after starting the new controller.
What happens?
No Ethernet connection to the controller can be established after a device replacement.
When does the behaviour occur?
If the SD card is inserted from the old controller into the new one during device replacement, then the controller does not adopt the IP address of the old controller when it is switched on. It is not possible to establish a connection with the new controller via the original IP address. The controller has the IP address '192.168.5.99' after the device replacement.
Which products are affected?
Controller c520 from V1.0
Controller c550 from V1.0
Controller c750 from V1.0
Short-term measures:
Copy the file 'IP.TXT' to the SD card of the controller in order to adjust the IP address accordingly after device replacement. The structure of the file is described in the online help.
Evaluation/Recommendations:
After a device replacement, an Ethernet connection to the controller via the originally defined IP address is not possible. This means that, for example, an HMI connected to the controller no longer works.
