Hello Husam! The most serial port connections (freeport) at the S7-200 are point to point connections (except: networks). It is not possible to share one port with more different devices or protocolls at the same time with a hub. There are no hubs on the market. But there are switches on the market. With them you can switch to an other device, like unplug the old one and plug the new one. Example (unfortunately a german shop): http://www.reichelt.de/index.html?SID=15sDRLGawQAQ8AABmfTRUcf919a4e1b4d17f8e80f8b9ce79a7575;LASTACTION=3;SORT=artikel.artnr;GRUPPEA=ED;WG=0;ARTIKEL=COM%20703;START=0;END=400;FAQSEARCH=Data-T-Switch%2C%202-fach%20Umschalter%2C%209-pol.%20D-Sub;FAQTHEME=-1;FAQSEARCHTYPE=0;STATIC=0;FC=8;PROVID=0;TITEL=0;ARTIKELID=6696;FAQAUTO=1;ACTION=3;GRUPPE=ED7 I hope I can help you!
