8.4 Verifying CODESYS License Applied

To test that the license is applied to the CODESYS Runtime system running on the EtherCAT controller perform the following steps

  1. Plug the CODESYS Key (USB Dongle) into the EtherCAT controller
  2. On the EtherCAT controller Linux terminal run the following command to start an instance of codemeter service
    • $ systemctl start codemeter.service
  3. Verify that an instance of codesyscontrol is running on your EtherCAT controller to connect the device to CODESYS Development System. Use one of the following commands to start an instance of codesyscontrol
    • $ /opt/codesys/bin/codesyscontrol.bin /etc/CODESYSControl.cfg
    • $ systemctl start codesyscontrol.service
    • $ /etc/init.d/codesyscontrol start
  4. Connect the CODESYS Development System running on the Windows PC to the EtherCAT network
  5. Open "Tools→ License Manager"
  6. Select "Device"
  7. Select "Dongle"
  8. Select the name of the device that is acting as the EtherCAT controller and click "Ok"
  9. A list of the license details shows up under the "Licenses" box on the left. This action can take a couple seconds to a couple minutes

    1. Another quick method to check if the license has been "applied" to the EtherCAT controller is to see if the green cycle symbol shows up next to the "EtherCAT_Master (EtherCAT_Master)" device in the left-hand panel
