Hi Sandra,
I use PCI6509 card to control actuators and relays inside a test station. Test application is developed in Teststand and CVI, using parallel model, running 6 UUT's. The output port lines are controlled by functions called by Teststand. The write function inside the DIO DLL is DAQmxWriteDigitalLines.
What I'd like to do, is to write a CVI application that will read the content of all the output buffers in the PCI6509, and display it on some graphical form. I tried an application that reads all 12 ports from time to time, using DAQmxReadDigitalU8, but this was not OK because it messes the configuration of all the ports, setting them as inputs.
At this point I'm stuck because I don't know how to read the output buffers of the PCI6509 using the NI-DAQmx driver functions.
