The vendor delivers this card with a Microsoft® 32-bit driver and an API provided by three
dll files pbmman32.dll, SsPbm32.dll and pbmerr32.dll. Alle available functions
are declared in various C-header files also available after installing the driver CD. The documentation
Pbmman32.pdf explains the usage of this API in detail.
In a simulation project to test automation solutions we needed the PROFIBUS® slave emulation features
of this PCI card under Linux and we developed the necessary linux driver for which we offer binary versions
limited to one card and 16 PROFIBUS® slaves to download for evaluation.
For a very complex automation project we simulated the behaviour of the whole machinery to
be able to exchange nearly 100.000 io signals in real time (1..5ms io cycle) from the simulation side via
PROFIBUS® with the real control equipment in real time. The simulation models where developed and
executed with our own simulator Poses++ and Matlab/Simulink in a hybrid simulation
environment of discrete event and continous simulation software like shown in the figure below:
