Hi Maha, DP/DP Coupler is not "useful" for S7-200. To connect via Profibus, look at How can you communicate data between the S7-200 and the S7-300 via PROFIBUS DP? . Another decision is MPI connection. Look at Communication between S7-300/S7- 400 and S7-200 via MPI . Be careful with MPI connection. There has restrictions regard speed and quontity of exchanging datas. Hope this will helps. Best regrards Hristo Mihalev |
