Hi, Maybe the firmware crashed. Operating System Updates for IM151-8 PN/DP CPU (6ES7151-8AB01-0AB0) If it comes to the worst... |

Hello, You shouldn't remove memory card while the CPU is powered. You have to erase its content using Promer and then reload the program on it once again. Why must you never remove a memory card when the S7-300/S7-400/S7-1200/S7-1500 CPU is in operation (RUN)? |
