DP/PA coupler, error LED

I am using the DP/PA coupler to connect a Profibus-PA by the device : CPU 317-2DP ( 6ES7 317-2AJ10-0AB0), SIMATIC DP/PA coupler ( 157-0AD82-0XA0 ) and Profibus PA (PR5350A). I have configured directly on the PROFIBUS DP master system of the CPU, however CPU 317  error  red LED BF and SIMATIC DP/PA coupler error yellow LED DP. 

Please guide me how to configure the device on?

Thank you very much, have a nice day !

Hello ht;

First thing, whenever you have a diagnostic LED active on the CPU, it is recommended to open the diagnostic buffer of the PLC to get more information on the cause of the fault.

You could also look at the meaning of the diagnostic LEDs on the coupler itself (see the attachment below), which can be found in the following manual:

SIMATIC Bus links DP/PA coupler, active field distributors, DP/PA Link and Y Link

Hope this helps,
