IC695PBM300 ask for advice

I want to use the IC695PBM300 RX3I control via PROFIBUS Siemens 6SE71 drive. Hope you tell me the specific configuration steps.Thank you

Step:
1. Plug the IC695PBM300 into the RX3i Rack.
2. Attach the network.
3. Install the proper GSD file.
4. Verify data lengths for each data type.
5. Write the PAC program.

I do not know how to Verify data lengths for each data type and Write the PAC program, which I do not know the specific data corresponding to the drive to start, stop, fault and so on. I am a beginner with RX3I. If you can tell in detail, it is best to help me send a case. Yes I am very grateful.
