If a Siemens PLC has to be connected with a PC via Ethernet, the normal way is to take a CP / Communication processor. IBHsoftec has a more flexible solution: IBH Link S7++. It is a cost efficient Ethernet-PROFIBUS-Gateway for programming, drive configuration, for communication between PC and Siemens PLCs, inter-PLC communication and FDT applications. It is possible to connect the IBH Link S7++ with a hub or switch or via a Crossover cable direct with your PC network card. The used protocol is standard TCP/IP, so you can control your system using VPN or a router. Of course you can also use an Internet connection. With the IBH Link S7++ online functions are possible via Profibus DP with up to 12 Mbit/s or via PPI/MPI. The IBH Link S7++ will reduce your cost because there is no need for the CP’s from Siemens nor the software Simatic Net is required.
The driver for SIMATIC MicroWin ,STEP7, WinCC, ProTool and of course S7 for Windows® is supplied on CD with your IBH Link S7++. Also you can use the IBH OPC Server to connect your visualisation with the PLC via IBH Link S7++. The IBHNet driver enables you to gain direct variable access via standard programming languages like Visual Basic or Delphi. The configuration of the adapter is very easy and normally done in a few minutes. The IBH Link S7++ automatically detects, whether it’s connected to a 10 or 100Mbit/s network. The IBH Link S7++ takes it's power supply from the MPI/DP interface, if available, otherwise via the integrated 24V plug.
Besides the programming capabilities also an application programming interface for HMI applications is included.
For Windows operating systems there are samples in the languages Visual Basic , Visual C, Visual C++, VB.net, Visual C#, Delphi, Java, Excel included. For Linux there are also samples included. After installation the samples can be found at:
