Forexample, the transparent XSAT attribute can be used for setting group controlling. TheTransparent XSAT attribute is used through an OPC client. The attribute uses the OPCdata type BSTR, which is a variant of VT_BSTR data type.The Transparent XSAT attribute passes on request the IEC 61850 servers and theirattributes outside the IEC 61850 OPC servers namespace. The IEC 61850 OPC serverdoes not check the outgoing attributes. Therefore the IEC 61850 OPC clients which areusing the Transparent XSAT attribute know what attributes they are accessing. TheTransparent XSAT attribute only supports read and write requests.The Transparent XSAT attribute uses synchronic data access in the IEC 61850 OPCserver. When an IEC 61850 OPC client writes a request, the IEC 61850 OPC serverparses and sends the request to the IEC 61850 server.The Transparent XSAT attribute returns and releases the request after it has receivedreply from the IEC 61850 server. The reply is written in the Transparent XSAT attributeas an XSAT string.701MRS758690COM600 series 5.0Master Protocols (Ethernet) and Applications Technical Refer-ence Manual
