Configuration3.About this section3.1.This section guides you in the configuration tasks required before you can start usingthe DNP OPC Server. For information on the IEC 61850 data modeling, refer to COM600User's Manual.Start Station Automation Builder 600 (later referred to as SAB600). Then either open aproject where at least one DNP OPC server is present, or where a new DNP OPC serverwill be added. You can also open and name a new project to include one or more DNPOPC servers.1. Select File > Open/Manage Project....2. In the Open/Manage Project dialog, select the required location for the project:• Projects on my computer.• Projects on network.3. Select New Project on the left.• Enter a Project Name. The Description is optional.4. Click Create.5. Click Open Project.Overview of configuration3.2.Before you can start using the DNP OPC Server, build and configure an object tree inStation Automation Builder 600 (SAB600) to define the Communication structure withinthe Gateway object. An object tree contains the following branches:• Gateway• DNP Serial OPC Server• DNP Serial Channel• Logical Device objects• Logical Node objects• Data objectsAfter you have added the necessary objects to the object tree in the communicationstructure, configure them.The configuration work can basically be divided into two separate tasks:1. building the object tree, and2. configuring object properties.First, build an object tree. This is done by adding objects to the object tree, see3.3.1, General information about building object tree.15COM600 series, Version 5.01MRS756567DNP 3.0 Serial Master (OPC) User's Manual
