Background information on BITBUS:

 

BITBUS is based on two solid standards:

• RS485 as electrical specification for reliable communication through rough environments up to several kilometers
• SDLC as a software protocol for compact, synchronous message transfer

 

Hence BITBUS provides a far more reliable connection than competing fieldbusses, for example those based on asynchronous communication.

Information about BITBUS, its protocol and installation can be found here.

 

You would want to program against BAPI, which is a uniform interface for the PC side, regardless of the BAPI-complianthardware underneath, be it USB, Ethernet or an add-on card. The BAPI DLL gets installed with the Windows® WDM driver, a similar mechanism is available under Linux.
