Can I use multiple network cards in LabVIEW?

Main software: PCI-6503 Controller module

Main software version: 1.0

Main software revision version: N/A

Secondary software: LabVIEW Development Systems>>LabVIEW Full Development System

Question:

Does LabVIEW support dual network cards?

Answer:

One way to distinguish different network cards through TCP is to use TCP Listen.vi and TCP Create Listener. vi. Both VIs have an input parameter called network address. Use the IP input function of a string to enter the IP address of the network card you want to use. Once the connection is established, you can output this reference using the connection ID or listening ID. This feature is commonly used in multi network card configuration. For more information about this feature, please refer to LabVIEW Help and other TCP functions.

When using TCP Open Connection, the operating system will determine which network card to use based on the IP address of the PC and which connection you are attempting to open.

When using FTPVI, there are actually two connections on the FTP server. The first connection is a command connection, where the command is sent; The second is data connection, which only involves the transmission of files. For command connections, the FTP server is the listener and the client is the open connector. There are two situations for data connections: active or passive. In an active connection, the data connection is opened by the FTP server, and the client is the listener (as opposed to a command connection), while in a passive connection, the FTP server is the listener, and the client opens the connection. The active setting is the default setting for most FTP clients, which means that we have a listener on our client side. The simplest way for LabVIEW to use a specific network card is to force the connection to be set to passive, by giving a false constant to the Active input of FTP Get File.vi and using the string to IP conversion function to obtain the address of the network card, which is then input to the host input of FTP Get File.vi.

Prior to LabVIEW 6.1

In LabVIEW 7, it is not possible to specify that LabVIEW listens to a specific network card. LabVIEW will open a WinSocket connection, and Windows will decide which network card to use. The most likely scenario is that the network card set as the primary network card will be selected.

Synchronization of multiple PXI-1042 chassis 10MHz reference clocks

Hardware: PXI/CompactPCI

Question: How to achieve synchronization of a 10MHz backplane clock for a multi chassis system?

Answer: The easiest way to synchronize the clocks of two PXI-1042 chassis is to synchronize the PXI of one chassis_ CLK10 OUT connected to PXI of another chassis_ CLK10 IN. However, this method introduces a time deviation between two clock waveforms. To reduce this deviation, an external 10 MHz clock source can be introduced into the PXI of each chassis through an equal length cable_ CLK10 IN connector.

What kind of cable should I choose for my Motion hardware?

Hardware: Motion Control

Question: I would like to determine what type of cable I should purchase for my NI Motion device. There are multiple options available on the Motion Advisors website, and what is the difference between so many cables? Which one is suitable for me?

Answer: PXIe-4463 Controller module

There are three suitable options, with PN numbers as follows:

186380-XX

186381-XX

189041-XX

Where – XX represents the length of the cable, for example:

-0R5: 0.5 meters

-01: 1 meter

-02: 2 meters

The differences between so many cables will be described below.

Cable 1: SHC68-C68-S, 68 pin VHDCI-68 pin VHDCI

PN:

186380-0R5

Both ends of this cable have the same 68 pin VHDCI male connector. This cable is used to connect the NI motion control card to the NI motor driver (such as MID-7604/7602) and the UMI-7772/4 connection module.

Question: I would like to determine what type of cable I should purchase for my NI Motion device. There are multiple options available on the Motion Advisors website, and what is the difference between so many cables? Which one is suitable for me?

Answer: PXIe-5641R Data acquisition card

There are three suitable options, with PN numbers as follows:

186380-XX

186381-XX

189041-XX

Where – XX represents the length of the cable, for example:

-0R5: 0.5 meters

DAQmx USB was unexpectedly terminated while buffering measurement items, and Windows Vista showed a blue screen.

Main software: Driver Software>>NI-DAQmx

Main software version: 8.3

Main software revision version: N/A

Secondary software: N/A

Question:

When the DAQmx buffer collection or generation process running on Vista was unexpectedly terminated, my computer rebooted or a blue screen appeared, with STOP codes 0x00000044, 0x000000fe, or 0x0000d1 appearing in USBPORT.SYS.

Answer: PXI-7852 Controller module

This is a problem with the NI-DAQmx8.5 driver. If the NI-DAQmx connected to the USB is running buffer collection or is accidentally terminated when generating tasks, it may cause the system to crash, and the computer will restart or display the Windows Kernel panic check (that is, the blue screen for crashes).

There is currently no known solution, and we will strive to fix it in the next version of NI-DAQmx driver update.

Conditions that may cause unexpected process termination include:

Using the Terminate Process action in the Task manager will stop the process

Use backend programs such as pskill to request stopping of processes

Shut down the computer at the command line (shutdown – r – t 0) while the task is running

Encountered access conflicts, breakpoints, or other unhandled conflicts

Attempt to log out, restart, shut down, or click Cancel when prompted by the process to exit or cancel

Terminate the process while debugging on LabWindows/CVI (TM) or Visual Studio.
