[arrietty 0]

Hi all,

My system is using PLC S7-300. Now, it is being SF fault. I followed the manufacturer's sf error instructions. I replaced the CPU Module, but it is still fault. Diagnostic of Simatic announced I/O can't access for reading and writing.

Please give a solution, thanks

Sincerely.
