It is a PLC/NC (Programmable Logic Controller) now for Compact PCI.

Yes it is a PLX-9050. The device uses interrupts, but why should I have to know that what type of interrupt it is? Until now I haven't found anything describing it. I could find out from the docs that it uses memory I/O and everything is done through a 8K buffer.
