Currently I have a PLC S7-1200 which does not let me connect via ethernet, so I can not see it directly on accessible devices. So, I tried to factory reset it from a Simatic Memory Card. I also tried to transfer the program from it and it does not change the RUN/STOP status. In TIA Portal I have already changed the START mode.
