task out with a shift register using ULx

[ccole]

This post below describes my same problem of passing a task through a case structure but they are using the DAQmx Library and it has a CreateTask.vi which the ULx Library doesn't have.

Any suggestions as to how to get my task out through the shift register?

Thanks

I have never had a problem getting ULx task out of shift register.

This is an action engine that I use to store the ULx tasks ref to use later in the code.

Thanks Omar,

May I ask what code you have in the False case? This is where my problem lies as I am getting an "empty I/O task" error.

It just passes the stored task ref through to be used by other VI to control the IO lines defined in the task.

It only creates a new task once when the program runs and the VI is called for the first time. The ref is not a valid ref.

Or the reset Boolean is true.

Have you used un-initialized shift registers before?

Post a copy of what you have tried before.

It's just an initialization problem then, nothing technical.

I should be good.  Thanks for your help.
