Thanks Ziko,
I was rather hoping that Pico could supply a more elegant solution for Pt100s. I'm in Belgium and use Rato in Antwerp as our supplier. I have ordered 4 Pt100 to 4-20mA converters from Conrad and will build my own module to add them to our Enviromon network.

Thanks Ziko, we are in a situation where if we cannot get DDE to work with the latest version of the software we will have to replace 3 complete Enviromon systems, as some things that we measure are now happening faster than your software can measure. I'm sure that there is a simple way of increasin...

Thanks for your reply Ziko, but I was hoping for a better response from Pico. You can hardly expect your customers to downgrade their software , which they have just upgraded to get the extra functionality, just because someone has forgotton to check that DDE works before compiling the new version. ...

Using the command/link =EMW|Current!Value just returns #N/A in Excel. Under further investigation the following VBA code gives a bit m...

I need to measure faster than 1 measurement per minute and would like to use DDE to write the current value to Excel and then use VBA to produce a short term high speed logger ( one reading per 10 secs ) Unfortunately the function =EMW|Current!Value just returns #N/A in software version R5.21.3 I sa...
