Task Behavior of NI-DAQmx Simulated Devices

NI-DAQmx tasks using NI-DAQmx simulated devices are verified just as tasks are on physical devices. If a property is set to an invalid value, the error returned for an NI-DAQmx simulated device is identical to the error returned for a real device. All resources necessary for the task are reserved for NI-DAQmx simulated devices. RTSI lines, PXI Trigger lines, DMA channels, counters, and so on are counted and reserved just as on physical devices. Finite tasks for NI-DAQmx simulated devices are done immediately, regardless of timing. Reads during a finite task return data immediately. Continuous tasks are done when you call the Stop function/VI. Reads during a continuous task wait for the data to be acquired as if the task were real.
