I have a problem, I have a PLC S7-314c 2DP connected with some other components to do a certain functionality, I don't have a Network module or Ethernet module,

Can I connect the PLC to the Visual Basic(for example) to read and write data via Libnodave or OPC or any other method

thx.

The driver for SIMATIC MicroWin® ,STEP®7, WinCC, ProTool and of course S7 for Windows® is supplied on CD with your IBH Link S7 Plus. Also you can use the IBH OPC Server to connect your visualisation with the PLC via IBH Link S7 Plus. 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 Plus automatically detects, whether it’s connected to a 10 or 100Mbit/s network. The IBH Link S7 Plus takes it's power supply from 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®, C++®, VB.net®, C#®, Delphi®, Java®, Excel® included. For Linux there are also samples included.

HMI applications can also connect via ISO on TCP (RFC1006) with a special RFC1006 Server.

Thanks for paying attention,
but is there any additional hardware required for using the IBH OPC server,
and what configuration or library required for VB or VB.NET to access the PLC via OPC.

thx. very much
