LabVIEW with MC DAQ: Error number 3134 has no text (?)

[hlee24]

Hi,

I am running a relatively simple VI (using LabVIEW 2020SP1 32bit) with a MC DAQ (USB-1208FS-Plus) that reads temperature signal. Sporadically, I get this error message but am having trouble to find out the cause as there is 'no text' as appeared. Anybody has any tip for this? Thanks in advance,

Hello @hlee24.

Which MCC DAQ device are you using?

Which version of LabVIEW are you using?

Please reply with your vi example?

Regards,

Fausto

Hi Fausto,

I am using USB-1208FS-Plus and VI is running on LabVIEW 2020SP1 32bit. I also attached the VI on the post above. Thanks in advance,

Hello @hlee24.

Thank you for the example file.

The USB-1208FS-Plus does not support temperature measurements.

Also, error 3134 is not from MCC's Universal Library.

Please consider a USB-TC or USB-2408, depending on your application's requirements.  Use the link below for alternative temperature measurement devices.

Hi Fausto,

I'm not entirely sure what you mean when you say that the DAQ doesn't support temperature measurement. We are actually able to successfully acquire analog input signals ranging from 0-10V voltage from a temperature controller, and it generally functions properly. However, there are occasional instances where the 3134 error occurs sporadically...

Hello @hlee24.

It was not clear the type of sensor being used for your temperature measurements.  The USB-1208FS-Plus does not support thermocouples.

Download and install the current MCC software on your target system.  Also, consider testing with a different PC to rule out an issue with your current target system.

Hello @hlee24.

Please confirm the serial number of your USB-1208FS-PLUS, as shown on the backside of the module or in InstaCal.

Error 3134 is not listed in the MCC UL error list nor in LabVIEW's error list.  Please test your USB-1208FS-PLUS with the ULx for NI LabVIEW example 'ULx Cont Acq&Graph Voltage-Int Clk.vi', which is included in the 'C:\Program Files\National Instruments\LabVIEW 20xx\examples\ULx\Analog In\Measure Voltage.llb' file.

 

I am unable to reproduce your issue, but your unmodified vi, along with your target system's specifications and configuration, may be the right recipe to create a collision/race condition.  It appears that you only use the analog input subsystem.  If the vi is acquiring data and it call the acquisition again, without having completed the initial task, then that could be your problem.  Verify that's not the case.

Please update to the current version of the MCC software, as previously posted. 

Regards,

Fausto

Hello @hlee24.

Attached is another vi example to test with your USB-1208FS-PLUS.   ULxAIAOScan_USB_1208FS_Plus.vi

The example outputs a waveform that can be captured by an analog input channel.  The example defaults to analog input channel 0 (screw terminal 1) and analog output channels 0 and 1 (screw terminals 13 and 14 respectively).  If the analog input channels were configured for differential mode, in InstaCal, then connect screw terminal 1 to screw terminal 13.  Additionally, connect screw terminal 2 with screw terminal 3.  If the analog input channels were configured in single-ended mode, then only connect screw terminal 1 to screw terminal 13.  Run the vi example.  The top graph should show you the waveform output specified in the bottom graph.  Allow the example to run.  This example works with my device and system.  If you get an error, then it may be your USB-1208FS-PLUS or target system.  Do you have another Windows system and/or USB-1208FS-PLUS to verify?

Note: If LabVIEW is unable to locate the 'ULx Waveform Buffer Generation.vi' file, then direct LabVIEW to the 'C:\Program Files\National Instruments\LabVIEW 20xx\examples\ULx\_Utility\_Utility.llb' file.

Fausto
