Helmut_13 Posts: 2930 Rating: (432)	Hi Essam, sorry I can't check it but in a S7-200 Plc you only have to move the data into the transmit buffer or move the data out from the receive buffer (if you want to transfere data you can't sread/write directly from the S7-200 Plc) In the Siemens support pages there is more information. Go to Google and search for: 747743 Siemens then you can find it. Basics: + same baudrate (only 19,2 or 187,5kB supported) + Plc's must have differnet station addresses (By default all PLC's ahve station adress 2) + use standard Profibus cables (noice reduction, termination) I hope this is helps. Regards Helmut
