problem with cp342-5 as aProfibus DP master

[kshok]

i have a confusion about how to use CP342-5 as a Profibus DP master with FC1(DP-send) and FC2(DP-recv),the system HW configuration is below.
my points of confusion are:
1- i can't access the ET200-M ( represents in HW config as IM 153 ) directly through the I and Q address ,but CP342-5 occupies 16 I bytes and 16 Q bytes starting from 288, what is the purpose of them ?
2-the modules of the 2 ET200-M have I , Q addresses from 0 to 31 , what are these addresses?
3-when using DP-SEND, CPLADDR=#16#120 (= 188) which specify which CP to use.
How to assign the parameter "SEND" to send data to the required module (say the module with redrectangular),please
give me example to do that?

note: i know that the CPU 315-2 DP has bulit in DP but i nees to make another network.

thanks in advance
