To connect a S7 200® ,S7 300® or S7 400® to a PC via Ethernet the standard method is to buy a CP / Communication processor and use it. But IBHsoftec offers another and more flexible solution which is the IBH Link S7++. This IBH Link S7++ can be used to connect your PC via Ethernet by connecting the IBH Link S7++ with a hub or a Crossover cable or a switch direct with your PC network card. Standard TCP/IP protocol is utilized so as to let you control the system with a VPN or a router or an internet connection. With the help of Profibus DP or PPI/MPI®, online functions are possible with IBH Link S7++ with speed ranging up to 12 Mbit/s. The IBH Link S7++ is also cost effective and will lower your costs for the lack of need of CPs from Siemens or the software, Simatic Net.
