HEIDENHAIN DNC and OPC UA NC Server
HEIDENHAIN offers two interfaces. HEIDENHAIN DNC (option 18) is a Windows COM interface used through the RemoTools SDK; integrators use TCP 19000 on iTNC 530 and 19003 plus 19010–19015 on TNC 640-generation controls. The OPC UA NC Server (options 56–61, one per connected application, or 3-02-1 on SIK2) runs on TNC 620, TNC 640 and TNC7 with minimum NC software versions.
