siemens Error PLC S7-300

5 posts in this topic

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.

More details of the system is really required but -

Is there any remote i/o (Profibus / Profinet)?

Are all the i/o power supplies ok?
