Profibus communication

Hello Dear all,

I have the following devices in my project:

1.S7-1200

2.ABB ACS800 Drive

3.CM1243 PROFIBUS Module

4.RPBA-01 PROFIBUS DP Adapter Module

And i am using DP V1.

Now, i want to use Read/Write services under PROFIBUS network.

In the RPBA-01 Manual, For example to send a request (Reading parameter value), i have to create a special format that contains DP Header and DP Trailer. 

I know that how to create the format for my requirements. but i don't know that how to program in my programming OB (OB1) and send it to drive.

May you please tell me that how can i do that?

Best regards
