I am trying to toggle a digital line on a USB-6621 using signal express with a switch on the operators panel. I have setup the first step as a digital line output (generate) and the second step as a digital line input (acquire) with a switch on the operator panel and bounded to the digital output line. When I run continuously without enabling the operator mode I am able to toggle the state with the value - to write radio buttons on the digital line output setup panel. However when I select the Use Programmatic Input option I get a missing input error? Any help would be appreciated
Hi there, see the picture attach. The problem that you are having is the order in which the steps were created. Simply invert them and the problem will go away.
Thanks for the reply. I am still not able to run. Yje Missing input error went away however I'm not able to bind a operator switch to the digital output and every time I run it I get an error that the device thr Requested Operation couldn't be performed because the specified digital lines are eather reserved or the device is not present in NI-DAQmx ..... The device is present and there no other task running. I attached a screen shot any help would be appreciated.
