Romi,
look at google for:
'DDE measurement value logging'
this gave me 1500 hits.
the German equivalent
'DDE Messwerterfassung'
gave again: 150 hits
Beside that there is a program (so far only with german help, but if you have
questions I can help) that maps DDE to socket so it is very easy to program
(see the telnet and the Perl examples) what you miss in Excel by yourself.

I think that is what you are looking for.
