SF Fault on S7 300

Hi All,

I have an SF fault on a processor that I am unsure how to rectify.  The attached Diagnostic file is attached. 

This system has around 20 profibus nodes that when the power is cycled they take a while to come back onto the network therefore in the log events 1 to 26 are related to that.

Event 31 is related to the 2nd ethernet port on the processor which is not currently plugged in - as OB82 can not be found I'm thinking this is the problem.

There are lots of faults showing P area, word access, Access address:    320

Address 320 is related to a FM350-1 counter module.

If someone could point me in the right direction that would be great.

Hello,

Distributed IO module with input address 2045 is failed. Please check.  

"Hello,

2045 is the diagnostic  address of ethernet port 1, I've just checked a program from way back when the SF was not lit and port 1 was set to ANY PARTNER, now it is set to:

HMI_1.IE_CP_1\PROFINET Interface_1 [X1]\Port_1 [X1 P1]

Which is on the network.

Could this be the answer?
