Connect to climate/temperature chamber in LabVIEW

Hi,
I'm sort of new to LabVIEW/a student and during my internship at a company I got an assignment to develop a remote control interface for the Weiss WT3 climate chamber for their tests. I'm using LabVIEW 2014 64-bit.
My previous experience in LabVIEW has been using the NI USB-6211 for remote controlling power supplies with analog voltage control and that is a bit more straight forward, I think.
Anyone with experience in this area that has any VIs that I can take a look at?
Here are some of the things I'm unsure of
How to connect it physically? There are Ethernet, USB and RS232 connectors as far as I can see
Use the bundled software with LabVIEW or only use LabVIEW?

Hi,
Thanks for the reply.
Sorry if the question doesn't make sense. I'm trying to articulate myself as best as I can (english is not my native language).
What I meant was that the oven comes with some software bundled with it to control the chamber via Ethernet, and I was thinking whether or not I am supposed to make LabVIEW communicate with that software (internally on the PC) or I should focus on somehow communicating with the chamber directly from LabVIEW.
I have succesfully used the application for remote controlling the chamber (although it does its job poorly, and has a lot of problems)
Unfortunately I'm not certain the manual is even available as a digital version anywhere. I know I've search a lot on the Internet for it, but without results. I only have a hard copy in the lab.

  • I need to control a Ransco temperature chamber with LabVIEW

           I need to
    control a Ransco temperature chamber with LabVIEW.  The temperature chamber requires four BCD digits
    plus a – /+ bit and some control lines.  I have a piece of hardware attached to my PC
    called LabJack.  LabJack has 16 digital
    input/outputs, 8 analog inputs and 2 analog outputs.  What I would like to do is control the
    temperature chamber with LabVIEW using the LabJack as an interface.  Has anyone in the group done this or something
    close to it before?  Also has anyone used
    LabVIEW to control a LabJack for any purpose? 
    I would be interested in looking at what you did and what drivers and VIs you used.
    Thanks,
    Gary

    Try reading this thread. It might not be terribly helpful to your application, but it might answer some questions. Also look at the Labjack site to look for the LabVIEW VIs that they have written.

  • RS485 connection to ESPEC climate control chamber

    Hello all,
    I'm having some difficulties setting up and RS485 link with a climate control chamber from ESPEC. 
    It is an ARL-0680 climate chamber. The climate chamber has two male DB9 connectors on the outside, apparently used for linking multiple RS485 chambers together. 
    The pinout of the DB9 RS485 intrerface connector is: 
    1:   SD+   Transmission data (A)   Connected
    2:   SD-   Transmission data (B)   Connected
    3:   RD+   Reception data (A)   Connected
    4:   RD-   Reception data (B)   Connected
    5:   GND   Ground   Connected
    6:   GND   Ground   Connected
    7:   NC    (Not connected)   Not connected
    8:   NC    (Not connected)   Not connected
    9:   NC    (Not connected)   Not connected
    I have bought a NI USB-485 interface cable. This cable also has a male DB9 interface but the pinout is different. 
    1:   GND
    2:   CTS+ (HSI+)
    3:   RTS+ (HSO+)
    4:   RXD+
    5:   RXD-
    6:   CTS- (HSI-)
    7:   RTS- (HSO-)
    8:   TXD+
    9:   TXD-
    So - the pinouts do not match and I see different signal names on both interfaces.
    Am I correct in assuming that I should only make the following connections:
    NI USB485   to   ESPEC climate chamber
       1                       5, 6
       2                       not connected
       3                       not connected
       4                       3
       5                       4
       6                       not connected
       7                       not connected
       8                       1
       9                       2
    Are there some special things I need to do in SW to get this setup to work? I'm using LabVIEW as my programming language to try and control the climate chamber. 
    I'm especially not sure how I need to set up the transceiver mode to get everything working...
    In the ESPEC documentation I could find that the communication system used is "Synchronized modulation (four-wire, half duplexing)".
    Thanks a million for all your helpful feedback!

    Hi KC
    Thank you for your reply.
    The USB to RS485 converter datasheet states the following:
    I think that being able to communicate in full-duplex it must support 4-wire RS485.
    I've read about that sometimes the + and minus are revered. Thinking on that I've tried the 4 different combinations. None of them worked
    The combinations are:
    First
    TXD -        RD -
    TXD +       RD +
    GND        GND 
    RXD -       SD -
    RXD+       SD +
    Second:
    TXD -        RD +
    TXD +       RD -
    GND        GND 
    RXD -       SD +
    RXD+       SD -
    Third:
    TXD -        SD -
    TXD +       SD +
    GND        GND 
    RXD -       RD -
    RXD+       RD +
    Forth:
    TXD -        SD +
    TXD +       SD -
    GND        GND 
    RXD -       RD +
    RXD+       RD -
    I also tried to debug the USB to RS485 converter with a null modem cable, first with the converter only and then with the cable I've assembled also. I was able to see echo on hyperterminal and I've noticed that TXD- transitions from Low to High (idle line state is low) and TXD+ transitions from High to Low (idle line state is high).
    I'm not sure if I need the termination resistors, since there aren't any references about this in both datasheets (converter and thermal chamber).
    I don't have any more ideas about this problem. I really would appreciate any help with this.
    Thank you

  • RTD Temperature Measurements using LabView 2013 and MyRio

    Hey everyone.  I am VERY new to LabView programming and working with a MyRio.  I need to figure out how to measure the resistance of a 2 wire RTD to find a temperature utalizing the MyRio and LabView.  I am pretty lost on how to do this.  Does anyone know some good resources for making the LabView program off of the tops of their heads?  I've figured out how to measure from specific pins, but I am not sure how to get it to constantly output a voltage from the output pins.
    Eventually, I would like to have it display the temperature as well as have it turn on or off a heater depending on that temperature, but that will come far later in this process. First things first, how do I take temperature measurements utalizing LabView 2013 and a MyRio with a 2 Wire RTD. 
    Thanks so much!

    Hi JoshEpstein87,
    The myRIO can't acquire a change in resistance directly, so you'll need to somehow convert the change in resistance to a change in voltage. There are multiple ways to do this, but you'll need to build an external circuit and then read the voltage output with the myRIO. One example of a circuit that allows you to do this can be found here. To output a voltage on the analog output pins, you should just need to set the output voltage and then it will remain at that voltage until you change it or power cycle the myRIO.
    To get started with LabVIEW and myRIO programming, see the following page:
    http://www.ni.com/myrio/setup/getting-started/
    There are some links to LabVIEW training as well as resources about RIO programming. I also highly recommend you check out the myRIO Community as there are example programs on there that you can take a look at to see how they are designed.

  • Connect third part opc client to labview

    I have no experience with Labview.  I need to connect a third part opc client to get data from Labview 8.5.  When I run the OPC Explorer and connect to the local server I see the data items.  However if I run the free OPC explorer from matrikon it does not find any OPC servers.  I see Variable Engine running in services.  Lookout 6.0 is set at manual and is not running (I don't know if I need this).  This computer is located in another country on the other side of the world and I only have RDP access.  What am I missing?
    Many Thanks

    Hello, 
    Are you using the DSC module?  With the DSC module you can add a 3rd party OPC client and bind your variables through that.

    Gøran Steen

    Gsteen,
    There are some examples in LabVIEW's Example Finder (Help menu -> Find Examples...) that might help.  Try Hardware Input and Output -> DAQmx -> Counter Measurements -> Position.  These examples are usually a great place to start.  I looked at "Meas Angular Position-Buffered-Finite-Ext Clk.vi" which looks like it may be of help to you.  You can also limit the example finder to only find examples that pertain to your hardware (USB-6211) by configuring the "Hardware" dropdown in the lower left-hand corner of the example finder.  If you are browsing, check the "Requirements" list in the lower right-hand to see if a particular example works with your DAQ.

  • How do I connect PeriMed Laser Doppler unit to LabView

    I am trying to connect a Laser Doppler unit to a AD-converter box for data acquisition on LabView 6.0. What cables are used to connect to the A/D I/O connectors on the BNC 2120. Thanks

    Greetings,
    The inputs to the BNC-2120 are standard BNC cables that can be purchased from most electronics stores. You will need a cable that has BNC on one end, to connect to the terminal block, and the other end must be compatible with the PeriMed Laser Doppler unit. You will have to determine what connection is needed on the PeriMed end from the manufacturer of the laser unit.

  • Could I connect the design in Multisim in LabVIEW 2009?

    Hi,
    I had design a generator in LabVIEW 2009, and now I need to send the output of the generator to pass through a transformer and a transmission lines. I found out that I could use Multisim to design the transformer and transmission lines. 
    I was wondering if anyone knows on how to transfer/connect the transformer and the transmission lines design in Multisim using LabVIEW 2009? In my final presentation, I need to use LabVIEW 2009 and show to my supervisor the result of the simulation.
    Ridhwan Ali

    Hi Ridhwan,
    Here are the options:
    1) You can save the results from the generator to a LVM file in LabVIEW. Then, go to Multisim and use the LVM_VOLTAGE (Sources Group, SIGNAL_VOLTAGE_SOURCES Family) source to open the file, connect this source to your circuit.
    2) You can create a VI in LabVIEW and use it in Multisim. Here is a good tutorial:
    How to Create a LabVIEW Based Virtual Instrument for NI Multisim
    3) You can control Multisim from LabVIEW via the Multisim API. Basically you can create a LabVIEW application that opens the Multisim engine, loads a circuit, and executes simulation. Basically you can bring simulation results to LabVIEW for further processing. More info:
    An Introduction to Multisim Automation with the LabVIEW Multisim Connectivity Toolkit (beta)

    I hope this helps. Good luck with your application!

  • CompactRIO shows as Connected - Running in NI MAX but Labview can't detect it

    I'm trying to get started with programming a CompactRIO. Yesterday I had a lot of trouble just getting the CompactRIO to show as connected in NI MAX, but now that it is connected Labview still can't find it. In the "Add targets and Devices" window the "Real-Time CompactRIO" folder shows "<No items found>" even though NI MAX shows the cRIO as "Connected-Running". Any ideas on how I can make Labview see the cRIO?

  • Connecting converted tool from VBAI to LabView

    Hey all,
    I'm really trying to connect to VI's together, one being a converted tool from VBAI and the other one, just a normal Labview coding.

    Dear Nathan
    I know I didn.t give much precision on that, but that's because I'm not so confortable with LabView, but I'll try and do my best.
    So to start with, I am using a thermal camera provide by a company called LAND. LAND has developed a few SubVI so that the thermal camera can be used on LabView. This is represented by attachment 1.
    Then, a few weeks ago, just for a trial, I have tried converting a tool from Vision Builder for Automated Inspection to LabView (no problems). After a little while, I manage to connect the new tool converted from Vision Builder (useless tool but just for trial; attachment 2) to the main SubVI, and data was coming out of all this (everything up until there was fine).
    Then the next thing was to create the tool I wanted to use on Vision Builder, which didn't take long and I converted it to Labview. But finally, when it came to connecting the main SubVI (attachment 1) to the usefull tool from VBAI I wanted to use (attachment 3), I couldn't manage to find my way.
    So this is what I am trying to do, that's to say, being able to use the tool developped in VBAI (attachment 3) to analyse the image I get from the main SubVI (attachment1) and get some data.
    Any kind of help would be highly appreciated.
    Thanks in advance

  • To develop an VI to aquire data of thermocouples from a remote chamber in labVIEW real time, should use NIDAQ or NIDAQmx?

    Hai
    I need to develop an VI to aquire data at real time. Am using LabVIEW RT as the OS and i need to know, if i can use NIDAQ 7.0 or should i use NIDAQmx? what is the diffrence between the two? is it just that NIDAQmx makes job simpler?
    Also can anybody please tell me, how to access a channel in labVIEW? am not clear about the path to follow to get the physical channel as a virtual channel on the LabVIEW.
    I am using a 8186 PXI with labVIEW RT and a SCXI, with both scxi and daq card on the same chassis.
    the development will be done on Windows XP which will be the host machine.
    Thanx in advance for any answers
    Arun

    Arun,
    DAQmx is our new Data Acquisition driver and should be considered as the primary option when writing new applications because of supportability in the future.
    DAQmx does make Data Acquisition tasks much simpler, abstracting many of the board implementation details and giving you a common API for 99% of the tasks you might want to accomplish.
    There are a couple of minimum requirements for using DAQmx on LabVIEW Real Time:
    - You will need LabVIEW Real-Time 7.1 (or higher)
    - You will need DAQmx 7.2 (or higher)
    These requirements are mentioned in the following Knowledgebase:
    Is NI-DAQmx Supported in LabVIEW Real-Time?
    The other thing you might want to make sure of is that DAQmx supports the DAQ hardware you already have or are planning to use. DAQmx does support most of the existing DAQ and SCXI hardware products, and reading thermocouples should become a very simple task.
    With DAQmx you can use physical channels, Global Channels (Aliases for preconfigured physical channels, equivalent to the Traditional DAQ Virtual Channels) or DAQmx Tasks (Preconfigured Data Acquisition tasks that include channel, timing and triggering information). A good place to start to learn about these features could be:
    Advantages of NI-DAQmx
    The following link might be useful to check Hardware support:
    http://www.ni.com/support/daq/versions.htm
    The driver can be downloaded by following these links:
    ni.com -> Support -> Drivers and Updates -> Current Software Versions -> Multifunction DAQ -> NI-DAQ Version 7.3 for Windows 2000/NT/XP
    This includes the latest version of DAQmx and our Traditional DAQ driver. Please note that DAQmx base is also listed but that's our Register-Level Programming (RLP) driver, which provides DAQ support for previously unsupported platforms.
    I hope this helps,
    Alejandro

  • Connecting Pumps to PC and Using LabView to collect the data

    Hello moizadi,
    the best place to start is definitely the excellent Example Finder built in LabVIEW (Help menu -> Find Examples...). Switch to the Search tab and enter the keyword RS-232. This way you will find nicely documented examples for other common tasks as well. You will find further tutorials and more specific examples by searching for RS-232 or serial communication keywords on NI.com search.

  • How to connect to SQL SERVER 2008 from labview

    We have installed a SQL server 2008 in the local PC and through DSN we were able to connect to the database on the same PC . Now we have loaded SQL server 2008 in another PC but in same network but we are not able connect to the database. we can do it with connnectiong string?

    Thanks for your reply, 
    We verified through DSN it works, we are able to connect to database by DSN.
    But the issue is for connecting it to database we need to dynamically obtain the IP by choosing the Obtain the IP address automatically in TCP/IP Properties.
    Whereas all the other devices connected to the PC are having static IP of 192.168.127.xxx from which we are getting the data. Also the PC IP address is 192.168.127.001 which is connected to the devices with a LAN switch to acquire the data from these devices.
    Now i can either communicate with the devices using static IP address 192.168.127.1 or connect to database using dynamic address. 
    A separate LAN port will solve or is there solution for this issue?
