FYI
Ad Profibus node adresses:
0 and 1 is reserved for PG and OP
2 is default for a Siemens CPU DP master.
3 is a common default for a slave unit.
Duplicate adresses will mess up the bus completely.

Ergo est; You should number your slaves from 4 and upwards.

Thanks a lot . the problem was solved
There was error BF and SF on cpu 314 .
FCM drive was not communicating with plc .
Station address assigned as 2 and bus address as 1 - which is correct . but still not communicating .
Actually there was miss assigned profibus network . I assigned it as profibus DP and type as ppo type 5

At last this problem solved . Thanks a lot for your feedback
