Hi, I'm working with two separate cDAQ 9188 chassis, both equipped with 9469 synchronization modules and 9205 Voltage input modules. The software is Labview NXG. I would like to configure the channels in the analog input task window, and then drag that task to the block diagram where I can read & write the data using the DAQmx commands. This is easy when the channels are all on one chassis, but with two it is giving me synchronization errors.
I read this tutorial: Synchronizing Analog Input C Series Modules with NI-DAQmx in LabVIEW NXG, which was very helpful, and it shows how to add channels through a constant or control from two different chassis, but I really want to add the channels from the tasks I created since it is easy to add, modify and test the channels in that window. Since I will be working with hundreds of channels, building 1 or more tasks appeals to me since it seems very organized and easy to setup.
I've tried using 1 task with channels from two different chassis, and I've tried two tasks with one channel each from different chassis with no success. I get the same error below when I run the VI.
Error -200436 occurred at NI:DAQmx:Internal:DAQmx Start Task.gvi:6610001
Start trigger delay is not available when an external sample clock source is specified.
Change the sample clock to onboard clock, or do not configure the start trigger delay.
Property: Start.Delay
Corresponding Value: 22.0
Property: SampClk.Src
Corresponding Value: /cDAQ3/?/SampleClock
Device: cDAQ2
Task Name: Analog Input_3
I am also open to other suggestions of clean ways to add and organize 100 - 200 voltage channels! I may be barking up the wrong tree here.
Thanks,
Kyle
