UA Part 7: Profiles - 5.4 Information Model and AddressSpace related features

5.4 Information Model and AddressSpace related features

Table 13 describes base features related items that can be profiled. For additional information about these items, please refer to OPC 10000-3, OPC 10000-5 and OPC 10000-6.
