Error -209838 Sync Lock Lost When Running an Executable

Issue Details

The Analog 1D Waveform N Channels N Samples VI is returning Error: -209838:
 

Synchronization lock was lost during operation. If the occasional loss of synchronization is acceptable, change the Synchronization Unlock Behavior property to ignore sync loss. Otherwise, go to ni.com for more information about sync loss management.

I am not interested in synchronization. How can I disable it?

Solution

Add a DAQmx Channel Property Node to the task, select the General Properties >> Synchronization Unlock Behavior property and set it to Ignore Lost Sync Lock.

This property will only appear if you have a TSN-enabled controller (such as the cDAQ-9189 or cRIO-9047) configured in NI MAX. To add this property without needing a TSN-enabled controller, see DAQmx Property Node is Missing Properties.
