Using OPC Toolbox Data Access Objects

---

To interact with an OPC server, you need to create toolbox objects. You create an OPC Data Access Client (opcda client) object to provide a connection to a particular OPC server. You then create one or more Data Access Groups (dagroup objects) to control sets of Data Access Items (daitem objects), which represent links to server items. OPC Toolbox Data Access objects are described in more detail in Understanding the OPC Toolbox Data Access Object Hierarchy for the Data Access Standard.

This chapter describes how to create and configure toolbox objects to interact with an OPC server. Reading, Writing, and Logging OPC Data provides information on how to use the OPC Toolbox Data Access objects to exchange data with an OPC server.
