How to generate two different analog signal in two different VIs

[ju13]

I'm using a PCIe-6321 board and a SCB-68 connector block. As it has two analog output I would like to use one of these output in one Vi to generate a square waveform and the other output in another VI to generate a sine waveform. Each VI work perfectly separatly but if I run one then the other, the second one doesn't send any signal. Since I don't want to merge the two VIs (It's more convenient to operate them separatly), how can I figure out to make them work together (sometimes).

I assume you get error -50103 (resource is reserved) at either on vi.

It's not possible to run two AO channels independetly from each other with different VIs since both Tasks are trying to request the same timing engine at the DAQ device.

Thank you. Is there any chance that it works if I add another card with another block?

Sure, independent cards with independent timing engines, controlled by independent VIs works.
