5.10 CODESYS License Management

The ED-PAC3020 device comes pre-installed with a CODESYS license by default. You can back up and restore the license by accessing the "PLC Setting" interface.

5.10.1 License Backup

Preparation:

A Windows PC has been set up with an IP address in the same subnet as the device. For example, if the device’s IP (1000M Ethernet port) is 192.168.0.100, set the PC’s IP to 192.168.0.99.
A functioning Ethernet cable has been prepared.

Steps:

Connect the device's 1000M Ethernet port to the PC via an Ethernet cable, then power on the device.
Enter http://192.168.0.100:8100 in the PC’s web browser to access the "PLC Setting" interface.
In the "Codesys License Management" interface, click "Backup License" to download the license file and save it locally.

TIP

The backed-up license file can only be restored on the same device.

5.10.2 License Restore

Preparation:

A Windows PC has been set up with an IP address in the same subnet as the device. For example, if the device’s IP (1000M Ethernet port) is 192.168.0.100, set the PC’s IP to 192.168.0.99.
A functioning Ethernet cable has been prepared.
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://192.168.0.100:8100 in the PC’s web browser to access the "PLC Setting" interface.
In the "Codesys License Management" interface, click "Restore License".

As prompted, select the obtained license file under a custom path.
After a successful License Restore, a 100% progress bar will be displayed in the right-hand panel.

Open the device’s terminal command pane, execute the following command, and restart the device.
