ERROR S7 1500

Desc:

LED flashes yellow, error led and maint led off.

The display is white and does not contain any information.

Can't find the CPU, the two X1 P1 P2 lights are always off even though I have connected between the CPU and my computer.

Is there a solution for me to fix this problem myself or should I send it to siemens service center

Is the voltage supply within specifications?

You said you've tried updating the firmware, did you follow the exact procedure as described below and did you use an authantic Siemens MMC?

To be honest i'never seen this on any 1500 CPU so i think you are in bad luck and will have to contact Siemens if the above steps didn't work...

i'm sorry

What is the part # of the memory module installed in your s7-1500?

Hi everyone, sorry my english is not very good.

I have a problem with s7 1513-1PN, possibly related to firmware.

Desc:

LED flashes yellow, error led and maint led off.

The display is white and does not contain any information.

Can't find the CPU, the two X1 P1 P2 lights are always off even though I have connected between the CPU and my computer.

I tried to upgrade the firmware using MMC, but still can't solve this problem.

Is there a solution for me to fix this problem myself or should I send it to siemens service center

Best regards.
