Use of VI express

I know that express VI is generally frowned upon here. My question is why?

Is it because people think that the programmer should be able to do (manually) that made the express VI?

Or is it because express VI generally perform not very well?

The reason I ask is because I know how to use the stuff of data acquisition, but I always use express VI when I need to send a large amount of data at once.

For example... If I need to read or write simple lines or ports I'll do it manually.

If I need to empty a buffer of 1 K on a map of FIFO memory, I will use an express VI.

Other people will tell you that their reasons for not using them. When screw Express was introduced experienced LabVIEW programmers seen with a lot of grief. In fact, there is a famous video which was taken at one of the meetings OR requiring experienced programmers to LabVIEW to screw Express name 10 they could not. Not because they didn't know LabVIEW, but because they stayed away from them. My personal opinion is that NEITHER basically was trying to take a cookie-cutter programming approach. On the one hand, they wanted to say that LabVIEW is a complete programming language. And on the other hand they wanted to say that the non-programmers could use it. That is why the live Express. When they came out first, they were terrible in terms of complexity and overhead. That they got the best. For example, the time Delay VI is very useful. So the elapsed time VI. So is the Fialog file.

Another reason why screw Express are frowned upward it is because data acquisition that they use dynamic data type which is a bit next to type of useless data. I'm sure that OR it will be just like being the greatest thing since sliced bread, but I'll take the data type of waveform on the dynamic data type of any day of the week.

  • Is it possible to use the AirPort Express to AirPlay only? (Wireless)

    Hello

    I have a speaker and I would empower AirPlay for it. I have an old airport express here in my house and I wanted to plug my express from the airport to my wireless network and allow the airplay.

    The only thing I don't want to not remove is the possibility to extend the wireless network, because I'm pretty sure it will do more bad then good, since I was a big of AC very close to the speaker wireless router. (http://www.asus.com/us/Networking/RT-AC5300)

    Is it possible to use the Airport express only airplay? Without trying to extend my network?

    Thanks in advance!

    Kind regards

    Tiago

    Yes, if you have the main router near the speakers... then simply plug the Express into the enclosure of the ethernet... Run it in Bridge mode and turn off wireless... Then check if you can find it in iTunes etc to send the stream of airtime.

    Or you can configure it to join a wireless network... it will not extend... Apple call it client mode.

  • Can I have the user enter a variable that will be used to Signal Express?

    We seek to use the Signal Express to collect data of analog sensors and load cells. We would like the user to be able to enter a variable that the program Express of Signal can act on. Is it possible within Signal Express?

    Hello

    When you select 'Change destination', it will fill with all stage settings that are supported for the given control used.  Not all the steps or step settings are able to be adjusted when the operator mode.  That is why you were only able to bind controls to step DAQmx Acquire and filter (they are only available to bind in your configuration steps settings).  The forumla node is not able to reference an entry of order of the operator interface. You must manually configure the formula tab of configuration step for that particular step.

    I would recommend if you want that more customized the user interface and approach programming using an application development environment.  Signal Express is ideal for acquisition of signals and perform analysis and basic treatment, but if you want more functionality LabVIEW would be a better option.

    1. you must set 'used source' "Always".
    2 If you use a PLSQL function as source type body should set a 'RETURN' statement like this:

    declare
    lv_date number;
    begin
    select to_char(sysdate,'D') into lv_date from dual;

    ADF7,
    the subject of the post has nothing to do with the question (for as far as I see it).
    As you can see the error message clearly comes from the procedure pl/sql you call the application module, works of groovy appeal method.

    We cannot decide what makes your service if you pass null as a parameter. You can check the settings before you proceed to the procedure or write the procedure in how it treats null parameters.

  • Error using filter with Expression SQL

    Hey all -

    New to Oracle BI and have a problem with filters that use the SQL Expressions.

    The column I'm filtering is a 4-digit year, expressed as a VARCHAR2(4 byte) in the physical database. My SQL Expression in the filter is:

    Column: CAL 4-DIGIT YEAR
    Operator: is in
    SQL expression: TO_CHAR (ADD_MONTHS (SYSDATE,-24), "YYYY"))

    When I click on the "Results" tab, I get the following error message:
    Error codes: YQCO4T56:OPR4ONWY:U9IM8TAC:OI2DL65P
    ODBC driver returned an error (SQLExecDirectW).

    Any ideas on what is causing my problem?

    Thank you!

    Yep, this should work, although sometimes you need an extra cast to CHAR.

    It works fine:
    SELECT "D0 time." "" Saw_0 T05 by name of the year ","recipes of F1. " "" Recipes 1-01 (all in all) ' saw_1 'Sample Sales' WHERE 'Time D0. "" T05 by name year ' = CAST (YEAR (TIMESTAMPADD (SQL_TSI_MONTH-24, CURRENT_DATE)) as CHAR) ORDER BY saw_0

  • Using the Airport Express Terminal as a bridge

    I would like to get video Amazon on my older Blu - ray player.  I was wondering if I could use my old AirportExpress (1st generation) as a bridge.  Now my new Comcast modem connects to my Time Machine that gives me my wireless connection. I tried to connect to the airport & connecting to my Blu - ray via ethernet cable, but I just get a flashing yellow light and the DVD on the screen tells me just the internet connection failed. Is this possible?

    Now my new Comcast modem connects to my Time Machine that gives me my wireless connection.

    I think that you wanted to say that you have a Time Capsule that produces the signal of your wireless network, correct? (Time Machine is a software on your Mac used to back up the Mac on another hard drive).

    I was wondering if I could use my old AirportExpress (1st generation) as a bridge.

    In 'bridge', do you mean you want the AirPort Express to receive a wireless signal of the time and then wireless Capsule to deliver one Ethernet signal to the DVD player?

    The answer is 'yes' to the offer that you really have a 1st generation AirPort Express. To check, look for the model number on the side of the Express in the small print. It starts with an "A" followed four digits.  A 1st Gen AirPort Express is A1264 model number.  What is the number that you see?

    I tried to connect to the airport & connecting to my Blu - ray via ethernet cable, but I just get a flashing yellow light and the DVD on the screen tells me just the internet connection failed

    Assuming you have a 1st Gen Airport Express, the device must be set up and configured to work with time Capsule. The AirPort Express doesn't quite work simply by plugging.

  • You can access time capsule iTunes library using the Airport express

    Hello

    I I have an Apple Airport express and listen to music from my iTunes library on my MacBook Pro. I have just bought a Time Capsule from Apple and saved my MacBook to this. I would like to listen to the music of my Time Capsule, as is always on.

    Anyone know if this is possible?

    Thank you

    Unfortunately, your new Time Capsule is not an iTunes server. This is, in itself, it can not stream audio files stored on the internal hard drive to an AirPort Express or Apple TV point. You will still need to use iTunes on your MBP to do. You would just point to the media library on your Time Capsule in the case of iTunes. (Note: However, if your iTunes library is stored on the Time Capsule as a Time Machine backup, this no longer works.) "It will take a stand-alone copy of the one that was on your MacBook.)

  • Using an Airport Express to listen to music - ethernet cable or not?

    My wife - who bought me an Airport Express 802.11n Wi - Fi for Christmas - was reassured in a certified store to which he would have a wireless connection to my existing wifi to stream spotify on my stereo, but I could not set up like that. According to Apple's Support, the Airport Express must be connected to a modem via an ethernet cable to work, which totally contradicts the advice she was given. This will not work for me - the stereo is in a completely different room for the modem.

    Who is right?

    I can't find clear indications on the web.

    Thank you very much.

    A "modem" , it's just that... a device that connects to the service of your Internet service provider to another router with a wireless Ethernet cable. "modem" does not any signal wireless... only an Ethernet signal.

    A ' modem/router ' or the 'bridge' is a device that combines the functions of a modem and router wireless in one package. It provides a signal of wireless network for other wireless devices can connect to the Internet wirelessly.  The modem/router or gateway also provides several Ethernet ports... usually 3 or 4... for devices to connect in this way as an option.

    An AirPort Express can only connect to a modem using a wired Ethernet cable connection.

    An AirPort Express can connect to a modem/router or Gateway using either a wired Ethernet connection or a wireless connection.

    Who is right?

    It all depends on if you have a modem... .or you have a modem/router, also called a gateway.

    If you do not know what you... then post back with the number of brand and model of the device that you call your modem... and we will try to find what it is you have.
