Figure 1: CommServer UA configuration

CommServer OPC UA server wrapper functionality allows to act CommServer UA as an OPC UA server that wraps the Classic OPC DA server (DCOM based) and creates the Address Space based on the XML model file obtained from Address Space Model Designer.

  • CommServer OPC DA Client - the essential part of the package that allows to connect and exchange data with Classic OPC DA server (DCOM based). This is the same component that is used also in DataPorter , so the configuration of OPC connection is the same as in DataPorter.

  • OPC Viewer - free software tool that is very useful for developers, testers, integrators, and others using OPC. This tool is able to generate Configuration.oses and DA_AddressSpace.odic files. Read more about configuration of the wrapper functionality in: Walkthrough: Create UA Wrapper.

  • Configuration.oses - this is an OPC Viewer session file. This configuration file contains information about configured OPC groups, subscriptions and items. Read more about configuration of the wrapper functionality in: Walkthrough: Create UA Wrapper.

  • DA_AddressSpace.odic - this is an OPC Viewer dictionary file. This file contains information about the address space of OPC DA (DCOM/Classic) server. Read more about configuration of the wrapper functionality in: Walkthrough: Create UA Wrapper.
