How to connect remote OPC Server using opcdaauto.dll using C#?

DLL used : opcdaauto.dll from OPC Foundation

        OPCServer ObjOPCServer;
        OPCGroups ObjOPCGroups;
        OPCGroup ObjOPCGroup;

        ObjOPCServer = new OPCServer();
        string _serverName = "Kepware.KEPServerEX.V5";

        //In place of "", I need to give IP address of machine where OPC Server is present
        ObjOPCServer.Connect(_serverName, "");

Then also I am not able to communicate . Any help highly appreciated.

Thanks in advance

            OPCServer ObjOPCServer = new OPCServer();
            OPCGroups ObjOPCGroups;
            OPCGroup ObjOPCGroup;
            //string _serverName = "Kepware.KEPServerEX.V5";
            string _serverName = "Matrikon.OPC.OMRON.1";

            ObjOPCServer.Connect(_serverName, "192.168.0.110");
            ObjOPCGroups = ObjOPCServer.OPCGroups;

            ObjOPCGroup = ObjOPCGroups.Add("Group1");
            ObjOPCGroup.DataChange += new DIOPCGroupEvent_DataChangeEventHandler(ObjOPCGroup_DataChange);
            ObjOPCGroup.OPCItems.AddItem("#MonitorACLFile", 1);

            //ObjOPCGroup.OPCItems.AddItem("Channel1.Device1.Tag2", 2);
            ObjOPCGroup.UpdateRate = 1000;
            ObjOPCGroup.IsActive = true;
            ObjOPCGroup.IsSubscribed = true;
