Overview

The NI DAQmx AI plugin acquires data from one or more channels spanning one or more devices with options to display, log, and publish data. Currently supported channel types include Voltage and Thermocouple channels. All of the core data acquisition features are exposed including channel definition, sampling, buffer control, triggering, logging, and more.

This version also includes the ability to decimate the display data to enhance performance, especially for high speed acquisitions. Data can be published with an averaging or last value strategy, and several key points of sampling information are provided as variables to build up the desired publish data object. Publishing can of course be disabled if, for example, logging the data to disk (ex. TDMS) is all that is required.

Custom DAQmx scales are also supported. DAQmx scales transform the raw, acquired data according to the scale definition. For example, analog input voltage acquisition may have a scale applied to transform the acquired voltages into some other physical units, such as temperature. The scaled values are the values displayed and logged. All current DAQmx scale types are supported: Linear, Range Map, Polynomial, and Table.

Furthermore, this version allows explicitly defining TDMS file formats with a acquisition.logging.fileNameFormat option, and allows adding custom properties to those TDMS files at the file level. See the configuration documentation and the “New to Version 1.2” sections below, and/or the example editor for further details.

The published data is configurable and may contain any the following:

{
    "publishTime": 12348761.12345667,
    "dataTimestamp": 12348760.12345667,
    "data": [0.5, 0.75],
    "totalSamplesSoFar": 1000,
    "acquisitionComplete": false
}

The publishTime and dataTimestamp here are defined as the number of seconds elapsed since 12:00 a.m., Friday, January 1, 1904, Universal Time [01-01-1904 00:00:00]. The data array contains the latest sample from each of the channels acquired (so the above example must be for an acquisition which has 2 channels configured). The acquisitionComplete boolean indicates whether the acquisition is complete, which will only ever be true in the case of finite acquisitions.

User Interface

The NI DAQmx AI interface is simple by design with a single graph showing current data according the configured acquisition. Parameters for the x-axis and y-axis are configurable and axes can be modified in real-time as well.

Required: false
Default: (not specified; see any element defaults within)
options.acquisition.channels[n]::{Voltage} object

The kind of the virtual channel (collection of physical channels).
Required: true
Default: "Voltage"
Enum Items: "Voltage"
options.acquisition.channels[n]::{Voltage}.name string
The name of the virtual channel (collection of physical channels). If you have multiple channels in the virtual channel, this name can be a comma-delimited list of individual channel names which will apply to the defined physical channels respectively. For example, if we specify physicalChannels as "Dev1/ai0:2", then we could specify the name here as: "MyChan0,MyChan1,MyChan2". Note that if you specify only one physical channel then you should not use a comma in the name as it would then only use the text before the comma.
Required: true
Default: "Voltage Channels"
options.acquisition.channels[n]::{Voltage}.terminalConfiguration enum (string)
Specifies the physical connection type. RSE stands for referenced single ended. NRSE stands for non-referenced single ended. Differential uses two physical channels and meaures the difference between a two-wire signal which will tend to reject noise. Pseudodifferential combines characteristics of differential and RSE terminal configurations. Like differential, it requires a two-wire signal and will therefore tend to reject noise (though generally the Common Mode Rejection Ratio, or CMRR, will not be as robust as for differential). However, because the negative terminal is technically electrically connected to ground through a small impedance (generally with resistive, capacitive, and even inductive aspects), grounds loops and other problems can occur if the negative terminal differs too much from chassis ground. Nonetheless this approach can be useful for floating signal sources where the negative terminal does not vary significantly from chassis ground.
Required: true
Default: "RSE"
Enum Items: "RSE" | "NRSE" | "Differential" | "Pseudodifferential"
options.acquisition.channels[n]::{Voltage}.physicalChannels string

Default: "Dev1/ai0:2"
options.acquisition.channels[n]::{Voltage}.minimum number
The minimum value expected among the physical channels. Make this value as close as possible to the signal minimum without going above the signal minimum. Note that this value helps determine the variable amplification which helps boost smaller signals closer to the full range of the underlying analog to digital converter, thereby providing better measurement resolution for those smaller signals. Also note that if a custom scale is applied then this value should be the minimum value expected after the scale has been applied. For example, if you have a raw signal (ex. voltage) with a minimum value of -5V and you specify a Linear scale with slope = 2 and yIntercept = 0, then use the -10 here (which will be in whatever custom units were defined in the custom scale).
Required: true
Default: 0
options.acquisition.channels[n]::{Voltage}.maximum number
The maximum value expected among the physical channels. Make this value as close as possible to the signal maximum without going below the signal maximum. Note that this value helps determine the variable amplification which helps boost smaller signals closer to the full range of the underlying analog to digital converter, thereby providing better measurement resolution for those smaller signals. Also note that if a custom scale is applied then this value should be the maximum value expected after the scale has been applied. For example, if you have a raw signal (ex. voltage) with a maximum value of 5V and you specify a Linear scale with slope = 2 and yIntercept = 0, then use the 10 here (which will be in whatever custom units were defined in the custom scale).

options.acquisition.triggering::{Start, Digital Pattern}.parameters.pattern string
The pattern on which to trigger the signal, to be used in combination with the triggerWhen option. For digital pattern triggering, you configure the device to detect a specific digital pattern on specific physical channels. After detecting this condition, the device performs the action associated with the trigger, such as starting the task or marking which sample was acquired when the trigger occurred. The digital pattern is specified using the following characters: X: ignore the physical channel. 0: Match on a logic low level on the physical channel. 1: Match on a logic high level on the physical channel. R: Match on rising edge on the physical channel. E: Match on either rising or falling edge on the physical channel. F: Match on falling edge on the physical channel. For instance, if you specify a pattern of 'X11100' and a source of 'dev1/line0:4,dev1/line6' the pattern match occurs when physical channels 'dev1/line1' 'dev1/line2' and 'dev1/line3' are logic high and when physical channels 'dev1/line4' and 'dev1/line6' are logic low. 'dev1/line0' is ignored. As another example (source specified as a port) if you specify a pattern of '11000000' and a source of 'dev1/port0' the pattern match occurs when physical channels 'dev1/line0' and 'dev1/line1' are logic high and the other six lines are logic low.

To avoid extra escape slashing in types such as objects, define the types of your properties here on an individual basis.
