S5 Migration to S7 and L2-DP Comunication

Hello guys,

I'm a newcomer here and, I a need help to define my network architeture before do my migration project.

The machine has a S5 (CPU 928B) and a comucation using SINEC L2-DP with:

• CS51 comunication unit (SIMOREG K);
• AS318B (Interface with a ET200);
• SIMATIC S5 IM316 (interface module to comunication with a SIWAREX P)
  

We will do change S5 PLC to a new S7 PLC (S7-1500), and we need to have the comunication with ET200,SIMOREG and SIWAREX P.

We are thinking to have a compatible Profibus comunication with these hardwares. Is it possible?

Wich kind of hardwares we need to have to do this comunication?

The migration guide talk about a IE/PB Link PN/IO to convert Profinet to SINEC L2, anyone here already use this converter and give an exemple of an application?

If you have a case of this application, can you share with me?

Thank you for your attention.

Best Regards!
