Hello Shahide043, If All the LED is Flashing Means there is a problem with CPU, CPU is Faulty, If it is under Warranty then Please Contact your Local Siemens with Serial No. (Normally you will find after MLFB no. Starting with S VPXXXXXXXXX) Or Contact Support Request... |

Hello Amit_86, If All the LED is Glow then Try to power On/off the PLC & then See, also During Power off Remove the MMC & Put it Back... Normally upto now I have seen all the LED Flashing means CPU is faulty, But I have not Seen All LED Glows Continuosly..... may be this is new case... |

Hello, What is the Problem in your case? Does all LED are blinking or continously glows? if all LED are blinking then might be CPU hardware failure. If it is under Warranty then Please Contact your Local Siemens with Serial No. (Normally you will find after MLFB no. Starting with S VPXXXXXXXXX) Or Contact Support Request Plese share more details about your problem. |
