3.1.2PIO_GetConfigAddressSpace

PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor, *wSubDevice, *wSubAux,*wSlotBus,*wSlotDevice)

•wBoardNo=0 to N Æ totally N+1 boards found by PIO_DriveInit(...)

•	wBase	Æ base address of the board control word
•	wIrq	Æ allocated IRQ channel number of this board

•wSubVendor Æ subVendor ID of this board

•wSubDevice Æ subDevice ID of this board

•	wSubAux	Æ subAux ID of this board
•	wSlotBus	Æ hardware slot ID1 of this board

•wSlotDevice Æ hardware slot ID2 of this board

The user can use this function to save resource of all OME-PIO/PISO cards installed in this system. Then the application program can control all functions of OME-PIO/PISO series card directly.

Find the configure address space of OME-PIO-D144
