Hello, Please check the manual in this link. In section 5.4, check the various configuration options for Profibus repeaters. SIMATIC RS 485 Repeaterhttp://www.profibus.com/uploads/media/03_PROFIBUS_Design_good_practices.pdf For more than one repeater in the network, don't connect them in star! Connect in daisy chain Hope this helps |
