Online diagnostic?

When i check the online diagnostics i got alarm "faulty" and "Fault LED (SF)". I have searched for an expanaition of this alarm but i am not able to find anything? Is there anyone who have had this problem before and have a solution for it?

Is it possible to say if this is a hardware or software fault?

I will post some more pictures with the status of the conected modules also.

Hello,

open the Diagnostic Buffer of the PLC and show which Fault messages are logged.

hello!

Please see attached file of the diagnostic buffer. It says PS2 Off and clear data of partner

Hello,

it looks that the Slave_1 have a problem or Diagnostic message present which cause the SF Errro.
You have also IO Access Errors, have you check the addresses of this error?

Hello,

"Slave 1 have a problem" Do you mean in my configuration or can it be a problem of the dp coupler which is connected in the other end?

"IO access Errors" this is also in the profibus device? In the documentation from the supplier they state that they use bit 0.0 to 4.7 but in the example in the same documentation they use adress 800-831 for slot 1 and 2? Can the problem be something with these settings?

Hello,

what is Slave_1 in you project ?

For the IO Access error look which address is logged and check which device have this adress in your project.
