On the control, under Settings, Network/Remote Access, OPC UA, Heidenhain's connection assistant trusts Dextrolab's certificate, gives it an OPC UA option, sets how it signs in and opens the control's firewall. Our team does this with you.
Yes. The OPC UA NC Server only accepts signed and encrypted connections, and Dextrolab signs in with its own certificate, which the control trusts first.
Yes. Each OPC UA option opens one connection: options 57 to 61 add more, for other software beside Dextrolab.
