Fieldbus Connection in The Visual Basic

The paper describes a new Windows based communication package which enables
standard Windows applications such as Excel and Access, and user designed
applications written in object orientated programming languages, such as Visual
Basic, to communicate with transducers and actuators via a fieldbus such as P-NET,
together with other standardised fieldbus types.
The paper includes examples of a simple Visual Basic programs, which display
and control field variables on a PC screen using P-NET transducers and
