I need to convert a program for PLC Siemens S7-200 Micro-Win to PLC S7-1200 TIA PORTAL.
You can use the Simatic converter tool and after check the errors.
The old program work with TD200 keypad, on the new program I use Weintek touch screen MT8073iE, so the part of TD200 no need to be converted.
I have also a program sample to communicate with inverter, via RS485 bus, to help you converting that.
Flash recording (Memory subroutine) no need to convert.
If I do myself probably 2-3 hours are enough so I want to spent less than 50 €
About the touch screen I made myself, based on your final program. We can discuss also about the Touch screen program.
