S7-314 2PN/DP Error LED (SF)

I am hoping someone can help me as I am at the end of my tether with this now.

I have changed 3 x S7-314C 2DP processors for S7-314C 2PN/DP ones but these are on a Profibus network. I can't get the network working correctly and I am getting both the Error (SF) and Error (BUS1F).

I have been through the old PLC code and can confirm that all of the settings (that I can see) are the same as previous but I must be missing something as it isn't working.

The diagnostic buffer in two of the processors shows no errors but in one of them I am getting this error for 4 of the addresses that the Profibus is communicating to.

Event 1 of 10:  Event ID 16# 2943
I/O access error, writing
P area, word access, Access address:    128
Requested OB: I/O access error OB (OB122)
Priority class:  1
External error, Incoming event
12:21:58.142 AM  01/06/2018
(Coding: 16# 2943  017A  0020  0080  0000  0000)

It is the same error but for Access Address 130, 132 & 134. All of these addresses are being written from this particular processor.

Any help is gratefully received as both me and my customer have worked through the night to get this working and had no success.

Ian

Hello Clarian.

Have you checked your HW configuration?

You can watch HW config online and see network modules diagnostics, you can see if modules are missing and figure out what to do.

 Thank you for your response, spent some time on the phone with Siemens and we have sorted it. We have three slaves on the Profibus network but we don't have control of the master. I went online with the master and the GSD files will need to be updated and the hw configuration sorted in the master but this is not our responsibility at this point as I uploaded from the processor. I thought it might be something obvious but I guess it is a perfect example of why working tired through the night isn't always a good idea.

Thank you for taking the time to respond.

Ian.

BTW, if the replaced S7-314 2PN/DP CPU's are of the same MLFB numbers, why you need to update GSD file of master? 

What do you mean - This is not our resposibility?

I just meant that it was supplied by others and without their consent and software I cannot access the processor, this has been done and now working correctly so thanks to all who responded.

BF1 is for Profibus.

You have a problem there?
