Hello,
I have an application controlling the cDAQ AI and XNET modules. I use Event Structures to handle user actions in dialog windows. This works well with the exception of the XNET signal control (both single and array). It seems that this control does not generate any value change events. Other XNET controls work normally.
Is it normal or am I doing something wrong?
Thank you in advance for your answer

It's pretty dificult to say without seeing what you're doing.

Hello,
thank you for the reply. OK, I attached a simple VI that demonstrates the problem. It uses the event structure to log every value change of any of the 4 controls on the left side in the text window on the right side. However, it works for the first two controls only. The XNET signal controls (3rd and 4th) obviously do not generate any event.
I use LabVIEW 2014 SP1 and NI-XNET 14.5. It behaves the same on 32-bit and 64-bit versions.

You are not alone. Apparently NI is looking into it.

Over on LAVA there is a crummy workaround until NI fixes this.
