Analog Output State of PXI Modules After Various Power OccurencesHardware: Multifunction DAQ (MIO)>>M Series>>PXI-6255
Problem: I am concerned with the state of the analog output channels on my PXI module after various power occurences, such as a power cycle or a software crash. Is it possible to tell what these channels will do? Solution: The two following scenarios address the state of the analog output channels after various power occurences. In both cases, the observed behavior can be exected for all M series boards as well as for any other AO series board. In the first scenario, a computer that is connected to a PXI chassis is unexpectedly shut down in the middle of an output process. When this happens, the analog output channels will immediately return to 0 V. The same results occur when power is unexpectedly cut off from the computer, but remains on to the PXI chassis, for instance if the cord to the computer is accidentally pulled out. In the second scenario, the MXI connection from the computer to the PXI chassis is disrupted. In this case, an indeterminable state occurs. The analog out channels will either remain at their last value or they will return to zero.
