I have CompactRIO 9004 with four modules.
I installed and configurated my device and I tried to test digital Modules.
I wrote a little VI to switch on DO 0 on NIcRIO 9472 (Digital Output Module) and It go ok!!
Than I tried to link DO 0 of NIcRIO 9472 (Digital Output Module) to DI 0 of NIcRIO 9421 (Digital IMput Module)
and I modified my VI like in Attachment.
The DO go ok and the led on module switch on, but DI doesn't work, the led of DI 0 doesn't s switch on!
Is it an hardware or software problem?
how can I understand how link the two module in the rigth way??
Thank you
