8.2 System Architecture

There are concepts for the system architecture of an OPC UA based CNC data interface illustrated in Figure 20 and Figure 21. Both enable to provide and realize the information model described in this document. However it has to be considered that there are OPC UA specific mechanisms used by this information model that need a closely coupled link to the CNC, e.g. the alarm and event mechanisms or the file access intents.
