O problema é o led SF/DIAG e está aceso e também o led Stop está aceso quando ligo a CPU. Além disso, quando muda a posição do interruptor de run para stop ou de stop para run, nenhuma alteração é vista. Ao tentar conectar uma CPU com o microwin via adaptador de PC, ele não detecta uma CPU. Também tentei conectar a CPU do PC colocando o interruptor em todas as 3 posições, RUN, Term, STOP, não está funcionando.Já averiguei as conexões cabos e troquei de adpatadores , PC e nenhum foi eficaz. alguém consegue me dar uma dica. ja pensei em dar um reset de fabrica o que acham? ------------------------------------------------------------------------------------------ Split from S7 200 CPU 224 SF/DIAG LED and STOP LED on.

This is the translation of your post (via google translate): AutoGen_2546832 I am facing a similar problem to yours on S7 200, CPU 226-2AD23-0XB0. The problem is the SF/DIAG led is on and also the Stop led is on when I turn on the CPU. Also, when I change the position of the switch from run to stop or from stop to run, no change is seen. When trying to connect a CPU with the microwin via PC adapter, it does not detect a CPU. I also tried connecting the CPU to the PC by placing the switch in all 3 positions, RUN, Term, STOP, it is not working. I have already checked the cable connections and changed adapters, PC and none were effective. Can anyone give me a tip. I have thought about doing a factory reset, what do you think? Kind regards, Moderator_Lan
