hi Rajesh,

see the manual of your CM1242-5:

SIMATIC NET S7-1200 - PROFIBUS CM 1242-5

chapter 4.2

Configuring in third-party systems

To allow configuration in third-party systems, a GSD file is available. You will find this on the

supplied DVD.

The protocol variant DP-V1 or DP-V0 is decided during operation by the setting of the

connected DP master.

 hope this helps, 

regards,
