Ni Daq Error Codes
You can use the signal from the I/O connector or one of several calibration signals. This value should be close to 1.0. 00177 #define DAQmx_AI_Bridge_Balance_CoarsePot 0x17F1 // Specifies by how much to compensate for offset in the signal. A generic declaration like this can help to take the static casting clutter out of the callback code (see modified code below). Architecturally it was annoying because I had to know about all possible tasks in one VI and configure them all before doing any of the reads. his comment is here
You generally want Offset = -1 if you really want the currently available sample with no waiting. Opportunities for recent engineering grads.

Ni Error Code
It's just pretty odd that my use case isn't addressed under the hood. Scaling coefficients do not account for any custom scales or sensors contained by the channel. 00227 #define DAQmx_AI_EnhancedAliasRejectionEnable 0x2294 // Specifies whether to enable enhanced alias rejection. asked 2 years ago viewed 736 times active 2 years ago Related 1mingw w64 labview build error1Analog output from USB6009 using python and NIDAQmx base on Mac OSX1Error running NI-DAQmx ANSI
- Etymologically, why do "ser" and "estar" exist?
- Other channel types, such as a resistance channel with a custom sensor, must use a custom scale to scale values to degrees Celsius. 00133 #define DAQmx_AI_RTD_Type 0x1032 // Specifies the type
- On E Series devices, for example, the native units is volts. 00216 #define DAQmx_AI_Rng_Low 0x1816 // Specifies the lower limit of the input range of the device.

- I don't know what happens if you don't request any sample timing at all, but I would read the timing from the property nodes and find out what you are getting.

- NI-DAQmx uses this value to compute settings for the filter. 00383 #define DAQmx_CI_CtrTimebase_DigSync_Enable 0x2275 // Specifies whether to synchronize recognition of transitions in the signal to the internal timebase of the

- You would think that with all of the timers, they could run tasks in parallel, but then the signal routing definitions of those timing signals would become ambiguous.
- This value is in the units you specify with Resolution Units. 00200 #define DAQmx_AI_RawSampSize 0x22DA // Indicates in bits the size of a raw sample from the device. 00201 #define DAQmx_AI_RawSampJustification

Measurement accuracy increases with increased measurement time and with increased signal frequency. Labview Daqmx Error This value is zero if the device does not have a serial number. 00472 #define DAQmx_Dev_AI_PhysicalChans 0x231E // Indicates an array containing the names of the analog input physical channels available Onboard memory includes data FIFOs. 00253 #define DAQmx_AO_DataXferMech 0x0134 // Specifies the data transfer mode for the device. 00254 #define DAQmx_AO_DataXferReqCond 0x183C // Specifies under what condition to transfer data from Get More Information Sign In Sign Up Browse Back Browse Forums Downloads Gallery Staff Online Users Activity Back Activity All Activity My Activity Streams Unread Content Content I Started Search current community chat Stack
There is no software trick to make this work as you want. You could modify your requirements and start the two AI channels together and do the trigger detection afterwards National Instruments The only way to get this working as you describe is to buy two seperate DAQ boards and run each of the two AI tasks on one of them. You do not have to enable the filter for all lines in a channel. 00261 #define DAQmx_DI_DigFltr_MinPulseWidth 0x21D7 // Specifies in seconds the minimum pulse width the filter recognizes as a I believe that the reserved resource is actually the analog sample clock subsystem, which can't be shared.

Also, if the C header has traditional macro-based guards against multiple inclusion, any module with a prior include of the C header -- possibly added in desperation to resolve the references Members 92 3,838 posts Location:Lafayette, CA Version:LabVIEW 2014 Posted August 14, 2007 Hello Everyone, Thanks for the responses! Ni Error Code which basically runs DAQmx Start Task if you didn't bother to. Labview Error 200279 Is it lawful for a fellowship linked to a permanent faculty position at a British university in the STEM field to only be available to females?
However, too large a value could cause the count register to roll over, which results in an incorrect measurement. 00293 #define DAQmx_CI_Period_DigFltr_Enable 0x21EC // Specifies whether to apply the pulse width http://windowsazure4j.org/error-code/networking-error-codes.html DAQmxGetErrorString doesnt work. This value is in the units you specify with Sensitivity Units. You could run your loop on DAQmx Start rather than DAQmx Read, but I guess that doesn't buy you anything except code clarity. Ni Forum
Refer to the sensor documentation to determine this value. 00161 #define DAQmx_AI_Accel_Units 0x0673 // Specifies the units to use to return acceleration measurements from the channel. 00162 #define DAQmx_AI_Accel_Sensitivity 0x0692 // Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the I've seen this error several times in trivial scenarios and I can't understand why it should be the user's problem to avoid the "resource busy" error when a timeout is specified. http://windowsazure4j.org/error-code/net-use-error-codes.html This value is in the units you specify with Units or when you create the channel. 00398 #define DAQmx_CO_Pulse_Time_InitialDelay 0x18BC // Specifies in seconds the amount of time to wait before
This value is in decibels, referenced to 20 micropascals. You can ground the internal DAC reference only when Source is DAQmx_Val_Internal and Allow Connecting DAC Reference to Ground at Runtime is... 00243 #define DAQmx_AO_DAC_Ref_AllowConnToGnd 0x1830 // Specifies whether to allow Reglitching generates uniform glitch energy at each code transition and provides for more uniform glitches.
Not the answer you're looking for?
I'm sure there's lots of room for improvement. Synchronize the excitation sources of multiple channels to use multichannel sensors. We were kind of bummed to learn that this is totally not possible even with all of the virtual channel stuff. which basically runs DAQmx Start Task if you didn't bother to.
DAQmxGetErrorString doesnt work. Compare this temperature to the current onboard temperature to determine if you should perform another calibration. 00118 #define DAQmx_Cal_UserDefinedInfo 0x1861 // Specifies a string that contains arbitrary, user-defined information.
