Building object tree3.3.General about building object tree3.3.1.The object tree is built in the Communication structure of SAB600, see Figure 3.2-1. Itis built by adding objects in a logical order starting from the OPC Server object.Before the IEC 61850 Proxy Server can be taken into use, you need to configure an OPCserver for the process communication. For more information on creating an OPC server,refer to COM600 User's Manual.You have two ways to add objects to the object tree in the Communication structure:• You can right-click the object to which you want to add a child object.• You can copy the object.First add the IEC 61850 Proxy Server OPC Client. The following objects are created bythe Proxy Configuration Tool, and should not be added manually:• IEC 61850 Proxy Subnetwork• IEC 61850 Proxy IED• Logical Devices• Data objectsAdding IEC 61850 Proxy Server OPC Client object3.3.2.To add the IEC 61850 Proxy Server OPC Client object:1. Add the IEC 61850 Proxy Server OPC Client object in the Communication structureby selecting the Gateway object.2. Right-click the Gateway object and select the server object, for example New >IEC61850 > IEC61850 Proxy Server OPC Client.Configuring IEC 61850 Proxy Server with Proxy ConfigurationTool3.3.3.Before configuring Proxy IEC 61850 Proxy Server, an OPCserver handling the IED communication needs to be configuredto the communication structure.To configure IEC 61850 Proxy Server with the Proxy Configuration Tool:1. Right-click the IEC 61850 Proxy Server OPC Client object and select Proxy ConfigTool.17COM600 series, version 4.11MRS757275IEC 61850 Proxy Server User's Manual
