s7-212 with s7-300 series communication

S7-212 and S7-315..

How can I make these two CPU's to communicate with each other?
Is there any MPI connection possible or PROFIBUS connection or maybe some other type of connection?

I dont have much time left...
Please, please, please help!!

Thanks!

Hello zrawi;
Try the following item on Siemen's Support wenpage:
www4.ad.siemens.de, and search for Entry ID 747743;
it shows you the steps to set up MPi links between a S7-300/400 and a 2nd generation S7-200.
It is also possible to use a profibus module on the \S7-200, but a lot more expensive.
Hope this helps,
