Hi MicroMan, Thanks for your reply.. If there is problem with HW card or rack similiar with this post PLC does not run : "STOP due to IO error" so in my situation is very strange, because after the problem occur and STOP it goes to RUN again after I COLD restart it. Is this situation impossible if there are HW or rack problem? |

Hi, If You can have a failing HW element on your MAIN RACK, and cold restart fix it, it means for me that the defective HW have an internal issue. Soon it will not run at all. I collected some literature to you, please have a look: 416-2DP stop caused by IO error ID 494D An FAQ about the similar issue on S7-300: Why does my SIMATIC S7-300 CPU go into STOP with error 16#4548 "Stop by I/O administration"? I hope I could help |
