Use what VI can Input/Output the Digital signal through PCI-DIO-96 and CB-50 I/O Connector Block. I have try to use 'Write to Digital port(8522).vi' and 'Read from Digital port(8522).vi' to do the I/O operation, but can't work.Why and How to do that
Both the Write to Digital Port(8255).vi and Read from Digital Port(8255).vi examples should function correctly with your PCI-DIO-96. The DAQ VIs used in these examples (DIO Port Config.vi, DIO Port Write.vi, and DIO Port Read.vi) are all compatible with this device. Have you tested your PCI-DIO-96 in Measurement & Automation Explorer (MAX) to verify that it is functioning correctly?
DIO Port Write.vi, and DIO Port Read.vi can work,but in my project ,I have to connect some physical circuit by using connector block. But I find that whatever I connnect the circuit, I can write data to my circuit by DIO Port Write.vi.
I am not sure that I understand the issue. Are you experiencing a problem when you connect a circuit to the device? At this point, are you no longer able to correctly read and write?
