W_7434_Initial (existCards As Integer, info As PCI_INFO)
As Integer
@ Argument
existCards :
The numbers of installed PCI-7432/33/34 cards.
The returned value shows how many PCI-
7432/33/34 cards are installed in your system.
pciinfo:
It is a structure to memorize the PCI bus plug and
play initialization information which is decided by
p&p BIOS. The PCI_INFO structure is defined in
ACL_PCI.H. The base I/O address and the
interrupt channel number are stored in pciinfo
which is for reference.

4.6 _7432_DI / _7433_DI_HiDW / _7433_DI_LoDW
@ Description
This function is used to read 32-bit digital inputs data from digital
input port. You can get 32 bits data from PCI-7432 by using
function “_7432_DI”, get 32 bits data (MSB double word) from
PCI-7433 by using “7433_DI_HiDW”, get 32 bits data (LSB
double word) from PCI-7433 by using “7433_DI_LoDW”.
