- The backed-up license file has been obtained.
Steps:
Connect the device's 1000M Ethernet port to the PC via an Ethernet cable, then power on the device.
Enter
http://192.168.0.100:8100in the PC’s web browser to access the "PLC Setting" interface.In the "Codesys License Management" interface, click "Restore License".
