Transparent XSAT

The Transparent XSAT attribute can be used to read and write IEC 61850 attributes,
which are not configured to the OPC namespace of the IEC 61850 OPC Server. For
example, the transparent XSAT attribute can be used for setting group controlling. The
Transparent XSAT attribute is used through an OPC client. The attribute uses the OPC
data type BSTR, which is a variant of VT_BSTR data type.
The Transparent XSAT attribute passes on request the IEC 61850 servers and their
attributes outside the IEC 61850 OPC servers namespace. The IEC 61850 OPC server
does not check the outgoing attributes. Therefore the IEC 61850 OPC clients which are
using the Transparent XSAT attribute know what attributes they are accessing. The
Transparent XSAT attribute only supports read and write requests.
The Transparent XSAT attribute uses synchronic data access in the IEC 61850 OPC
server. When an IEC 61850 OPC client writes a request, the IEC 61850 OPC server
parses and sends the request to the IEC 61850 server.
The Transparent XSAT attribute returns and releases the request after it has received
reply from the IEC 61850 server. The reply is written in the Transparent XSAT attribute
as an XSAT string.
