connect with profibus without EM277 not posible,
connect on MPI it is possible..

connect with OLD school IO communication always a solution.

Hello

You already understood without Em277 it's not possible to establish Profibus connection. S7-200 can only be profibus slave. If you have EM277 look at How can you communicate data between the S7-200 and the S7-300 via PROFIBUS DP? ( http://support.automation.siemens.com/W ... en/2615830 ). In this link you'll find GSD file for EM277.
Other possibility-connection via MPI, look at http://support.automation.siemens.com/WW/view/en/747743 , but this type of connection has some restrictions, be careful. :wink:
Hope this helps
regards
