can you give an idea how to upload the program from TD17 to PC?

 

Hello;

The only way you can upload a program from a TD17 is a utility called Prosave:

Note that the program you can upload will be compiled (not enough memoty in the unit to hold the uncompiled version), so the only thing you can do with it is download it to a new unit.

Hope this helps,
