OPC Unified Architecture – Part 81: UAFX Connecting Devices and Information Model
12 OPC UA FX Instances
12.1 Overview
The OPC UA FX Information Model defines well-known instances (see Table 252 and Table 253) that are used to group OPC UA FX Object instances. OPC UA FX Object instances may also exist in other Folders or in other groupings. Figure 64 provides an overview of these instances.
