Note that DDE is a very old technology which was superceded by OLE which in turn is embedded in OPC technology.
For accessing live Data in Excle with 800xA on top of an Advant system you can use DataDirect which is available directly from any node via the CS nodes in an 800xA system with 800xA Advant Connect.
I think DDE is obsolete and slow protocol to be used in the 800xA system.
In 800xA "MOD300 Connect" feature provides data exchange with MOD300 DCN using MOD300 OPC Server.
"There shoul be some option like where we have to type tag name , whether it is live data or historic data." - typing tag names no needed in case of 800xA MOD300 Connect. You can upload whole MOD300 tags database to the 800xA aspect directory. In this case tags will automatically be imported in the Plant Explorer control structure.
Later (as was already mentioned above) you can use DataDirect to import/export data from these tags to the Excel)
