All of your setup is hidden in the task that you created so I have no idea what else might be wrong. Do you get an error?

should it be a task? I have it as a Global Channel.

It looks like the digital channel is set for a software timed single sample. If you create a task, you can specify timing. There are also examples that you can look at where the timing and other configuration is set on the block diagram. You need to provide a clock source and use the correlated I/O pins for a hardware timed output.
