Hello,
I war working perfectly fine this morning and when I come back to this after just stepping away for not even 5 minutes and I now have the following issue when debugging and testing what I am working on.
I have a cDAQ-9185 on latest firmware with Labview 202 Q3. (This is the chassis with two ethernet ports only for connection.)
It has the following cards:
1) NI-9201
2) NI-9375
3) NI-9482
4) NI-9485
It seems it is failing on the Start Task which is then cascading into the read and write blocks. The channels are specified on the Front panel for now during testing.
I have tried both ports, renaming the cards, trying the main VI in a standalone separate project, reseating the cards, pushing the reset button and power cycling it. I know I can communicate with it given it worked before and I can still ping it.
Full error says:
"Error -209836 occurred at DAQmx Start Task.vi:7220002"
"Possible reason(s):
The devices in your task cannot be synchronized. This may be because there are no available synchronization mechanisms between the devices.
Some synchronization paths are not available in interactive tools like the DAQ Assistant. To determine whether synchronization between these devices is possible, try deploying and executing your task in your application environment.
Task Name: _unnamedTask<90>"
Any help would be greatly appreciated for this unexpected issue.
Thanks.
