Hello tekabi; Why would you want to limit interventions from forum members to "experts"? Don't you think that replies from enthusiastic amateurs can sometimes be a lot more informative and helpful when you face a problem? To answer your question simply: no. Unless you have some kind of analog-to-digital circuit that can decode the 16-bit analog value to 16 digital signals; then you could connect these to 16 digital inputs, read them all together as a single word, convert the reconstructed analog value to an engineering value... Sounds like a lot of time, design and trouble that could be easily avoided by locating and EM231 module and using scaling functions of Microwin. Hope this helps, Daniel Chartier Edit; If you do want to study the requirements for Freeport comms on the S7-1200, you could look at the following Discussion; our friend JBell proposes a link to the S7-200 Tips and Tricks that proposes a few sample programs using Freeport communications. https://support.industry.siemens.com/tf/ww/en/posts/6183/ But you will need some kind of analog-to-serial converter, either as a single-chip microcontroller, or an Ardyuino/Rasberry PI project, in order ot generate the converted analog value and transmit it in a form that can be understood by the Freeport protocol.
