hi, can you access the CPU? Have a look in the Diagnostic buffer and share it with us for further diagnostics. from the manual these LED- displays can be: with Run flashes 2Hz: The CPU is in startup mode. with Run flashes 0,5Hz: The CPU was halted by a programmed break point. You find this Status and error displays in the following manual, chapter 10.8.2 : SIMATIC S7-300 CPU 31xC and CPU 31x: Installation hope this helps, regards, |
