Split from SF and BF faults in Simatic S7-400.

Hi,

is the memory card a new one or was it working in another PLC?

--> ift it´s not new, you should delete Files / Format with Step7 USB Prommer or PG.

Look to this FAQ to check if MMC is defect:

How do you reset a SIMATIC S7-300 CPU and MMC (default reset or overall reset)?

Hello nabeelo,

Please check the date of post you replied. 

if you want to reinstall a new one insted of old one you should go into the accesible node in online mode and delete all of memory data .also be ensure that two memory has the same version

another that : if you have fault you should chek plc can access all of real I/O or not .

New question published by Tanzeal is split to a separate thread with the subject 315-2pndp, BF is blinking.
