Indicates if the device(s) detected an open current loop for any channel in the task. Reading this property clears the open current loop status for all channels in the task. You must read this property ...

The following tables lists the default input terminals for various counter measurements. You can use a different PFI line for any of the input terminals. To change the PFI input for a measurement, use ...

In physical channel names, cDAQ1Mod1 is the default device name for a C Series device plugged into a USB or Standalone CompactDAQ chassis, where cDAQ1 is the default chassis device name, and Mod1 refers ...

C Series devices do not support hardware-timed single-point sample mode or Wait for Next Sample Clock. Analog Input Timing Considerations for C Series Devices You can use multiple analog input devices ...

For C Series devices, you can filter digital I/O lines and digital input signals. Timing and Triggering Filters for Digital I/O Lines You can configure digital filters on the device by choosing three fixed ...

Internal channels for the FD-11613 The following internal channels are available. Internal Channel Name Description FD11613-xxxxxxx-Bank1/_cjtemp0 This channel is used for cold-junction compensation. FD11613-xxxxxxx-Bank1/_cjtemp1 ...

Specifies in samples per channel an offset at which a write operation begins. This offset is relative to the location you specify with RelativeTo. Not supported Not supported in VIs that run in a web application ...

Two NI-DAQmx Read/Write attributes/properties allow you to check for disconnected sensors. The first is OpenCurrentLoopChansExist. This attribute/property returns a Boolean true if one or more channels ...

A counter contains several advanced terminals that you can use to perform time measurements and generate pulses. For most applications, NI-DAQmx automatically makes the proper routes from the terminal ...

Real time means that responses occur in time, or on time. With non-real-time systems, there is no way to ensure that a response occurs within any time period, and operations may finish much later or earlier ...

Indicates the name of the internal Reference Trigger terminal for the task. This property does not return the name of the trigger source terminal. Not supported Not supported in VIs that run in a web application ...

Specifies the terminal to which to route the Reference Trigger. Not supported Not supported in VIs that run in a web application 590 attr590.html

On an X Series device, you can either acquire a signal present on the I/O connector, or you can acquire a signal that is being generated from the internal calibration multiplexer. The channels available ...

Requirement The I/O needs to be hardware-timed. All output values need to simultaneously update at the arrival of the sample clock edge. Data needs to be exchanged between a time-critical loop and lower-priority ...

Specifies in hertz the rate of the digital filter timebase. NI-DAQmx uses this value to compute settings for the filter. Not supported Not supported in VIs that run in a web application 2F02 attr2F02.html ...

The resolution and device range of a measurement device determine the smallest detectable change, called the code width, in the input signal. The smaller your code width, the more accurate your measurements ...

The following table lists the revised names for digital terminal names. Original Terminal Names Revised Terminal Names Explanation DIO# P0.# Ports on devices are referred to by a number. Port A is called ...

Quantization error is the inherent uncertainty in digitizing an analog value as a result of the finite resolution of the conversion process. Quantization error depends on the number of bits in the converter, ...

To explicitly start a task, call the Start Task function/VI. You auto-start a task when you perform some other operation that implicitly starts the task. For instance, calling a Read function/VI or a Write ...

Master Timebase synchronization is the most flexible and powerful synchronization method available on supported devices. It allows you to synchronize all timing for the synchronized devices, even at different ...

Task-based routing is the most common form of routing. When you create a hardware trigger or export a hardware signal, you create a task-based route. These routes are embedded in a task. You can use Export ...

Terminal Names Explanation OnboardClock An alias for the terminal within a device where the default source for a clock can be found. If your application does not set the source of a clock (or uses an empty ...

The limitation on t0 is that NI-DAQmx calculates the starting time for the task when data is read the first time. At this time, NI-DAQmx calculates the starting time for the task by reading the current ...

Indicates a list of names of any virtual channels in the task for which the device(s) detected an open current loop. You must read OpenCurrentLoopChansExist before you read this property. Otherwise, you ...

Specifies the state to set the counter output channel terminal when the watchdog task expires. Not supported Not supported in VIs that run in a web application Low 10214 Low logic. High 10192 High logic. ...

When you include channels from multiple C Series modules in a task, NI-DAQmx automatically synchronizes the modules. A task can include channels from multiple C Series modules, given the following conditions: ...
