Same problem here, RUN/STOP LED yellow, ERROR LED red. The CPU worked last week but today no communication whatsoever (TIA V11, PST 4.1, ping, ...). I have other cpuswith different ip address and all is ok with my computer.I tried the memory card reset procedure (https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=40588092&caller=view) but the cpu doesn't even read the card (and I use a Siemens memory card working on other cpus). The CPU looks to be dead... Since I'm not the first one to have this problem, is there a documented issue with the 1200 CPU causing this ? And a fix to this appart form replacing the cpu... |

I have not had this kind of problem. What PLC and what firmware? I think a few s7-1212 FW3.0 had firmware related problems similar to what you describe. I suggest you contact Support Requestand alert them of the problem. |
