Is it possible to direct connect Omron PRM21 and Siemens CPU314-2DP (as slave) without using the DP-DP coupler ?

I have the following configuration:
- Master Profibus DP CJ1W-PRM21PLC OMRON
- Slave Profibus Pushbutton panel PP17-ISIEMENS GSD : siem8065.gse V 1.1
- Slave Profibus SIMODRIVE 611U SIEMENS GSD : si02808f.gsd V 2.3
- Slave Profibus ET200M IM 153-1 SIEMENS GSD : siem801d.gsd V 1.25
I did not face any communication problem with PP17-I and 611U Simodrives .
I did the setup and GSD file through OMRON CX-PROFIBUS software , and it works
I can read and write data to these units
but I could not get Data exchange with ET200M IM153-1 INTERFACEUNIT .
ET200M : 6ES7 IM153-1AA03-0XB0 COMMUNICATION INTERFACE MODULE
6ES7 IM321-1BL00-0AA0 32 DIGITAL INPUT UNIT.
DIAGNOSTIC indicates : 1- configuration fault .
2-station not ready.
3- reparameterization requested.
NOTE :By the wayOMRON MASTER PROFIBUSis ASPC2 SIEMENSIC &
IM153-1is SPC3 SIEMENS IC .
Please advice me how to solve this problem , how to set the proper parameters and is there any other GSD file for 6ES7 IM153-1AA03-0XB0.

I am facing simmilar problem when connecting this OMRON PRM21 to SiemensCPU315-2DP as slave.(6ES7 315-2AG10-0AB0).
When I changed to use a DP_DP coupler (6ES7 158-0AD00...), every bit zero exchanged between the two masters was set to 1.
