Mike,

I tied to incorporate your example into my VI. However,  I cannot seem to actually get  the VI to write to the specific channels now. The VI runs, the timers work , and the indicator lights work, but no actual writing is happening. I have attached what I have done so far. What  am I doing wrong?

Hi nick525,

do you get an error message? Try to change the auto cleanup from create task to false.

I am not getting any error message, and changing that value to False has no effect. I am really not sure if I configured everything correctly, as there is no digital out being written (the digital out is being used to apply a voltage to a relay, and it is not doing that).

Hi nick525,

in your latest example you use single channel to write but now you have more than one channel you have three now. Try to change it. Hope this helps.

Mike,

I'm not really quite sure what you mean. I thought I was using a single task to write to three channels. I am very sorry for being so confused, but I am very new to LabView. What do I need to change to write to three channels, as you suggested?

Hi nick525,

click under the write vi, where you can select the type of vi. Select Digital -> Multiple Channels -> Single Sample -> 1D Boolean. See the attached picutre. The red circle marks the click position
