Since i dont have access to Tia portal Software so seeing online diagnostic buffer is not possible.
The only thing i could do was replace the "Old Simatic Net Cp module 6PGK7 342-5DA01- 0XE0"
with "New Simatic Net Cp module 6PGK7 342-5DA02- 0XE0".
Result: New simatic net Cp's led indication displayed Flashing BF.
(is it problem with profibus/ should i configure address of profibus slave)

Thanks in advance
