Hello Solution Riders can't say for sure what's wrong based on the supplied info, but suggest you check first if the following could be the cause. What do you have to do if the SIMATIC S7-300 CPU no longer goes into RUN mode after adding a CP or FM module? If not, please provide us with more detail (the usual suspects like part numbers, Diagnostic buffer content, etc.). I hope this helps |

Hello Solution Riders I think: This may be bad contacton back bus(bad busmodule in rack)or on power terminals in CP. Extract CPU and CP from Rack and insert it's back. May be need change busmodule |
