Hello Frédéric, in Version WRK-V-0106 there exists a bug opening a synchronized project from the control in the webbrowser opend via the IpV6. A workaround is to start the browser with the IpV4 address. The second problem is that the PLC Address of the control is not set correctly. Try to enter the IpV4 address into the field below the control in the communication settings page (double click on the controller in PLC Engineering). The third problem can be solved by activating encrypted communication for the control. (Should be activated by default). Refer to Encrypting Communication, Changing Security Settings Regards, Oliver
