ProfiM - Profibus Master
free implementation of industrial protocol Profibus DP

http://profim.sourceforge.net/

ProfiM project aims to support fieldbus Profibus by use of a
common PC without use of special hardware.

The work implements bus control unit (master) for Profibus DP
(Distributed Peripherals), which is most widely used variation
of IEC 61158/IEC 61784 standard. It's designed for communication
between control units and distributed peripherals (sensors, actuators).
Commonly used solutions are expensive, because they are built
on special expansion cards, which are using their own processors,
customer's circuits or another circuits with enough power to meet
high requirements of Profibus.

On the other side, this work allows for connecting Profibus to standard
serial port RS-232 or to simple PCI expansion card based on UART circuit.
Profibus DP Master is created as software implementation and special
features of hardware implementations are substituted by maximal use
of common means in PC. This was mainly possible by creating Profibus DP
Master as system driver for Windows NT/2000/XP. Moreover application
interface is compatible with solutions from Siemens company,
which allows for simple replacement.
