All right, it is the LED green 'OK' that ignites then goes out as if the food(supply) 220v disappeared, while it is always present. |

this can be a problem, if you don´t have SIPLUS-modules. the climatic environmental conditions of S7-300 modules are from 0-60° Celsius. Have a look in this manual, chapter 11.4: SIMATIC S7-300 CPU 31xC and CPU 31x: Installation
hope this helps, regards, |
