Framework of the CJC to SCC-TC02

I use a SCC-TC02 thermocouple module in the carrier of CSC SC-2345.  The DAQ card that I use is the PCI-6221.  I understand that the SCC-TC02 has an onboard thermistor for cold junction compensation.  When you set the parameters for the DAQmx create Channel.vi, I put the CYC Source Built in.  In doing so, I guess nothing else needs to do for cold junction compensation (no conversion software, etc.)  I enclose my vi.

Thanks in advance.

Without compensation of CJ, the error would be based on what the cold junction temperature is against what you typed in as a constant.  So if you said the room temperature was a constant 70degF, but in realtiy 75degF, then you will have 5 deg F error in your reading.

  • A few questions on the framework of the actor

    Hi all

    I tried to get my head under the actor and begins to see the light at the end of this tunnel-no need of sunglasses right away, because I have a few questions remaining:

    1. data transfer :

    So far I've had a quick glance the evaporative cooler model and actor model, as well as worked through the LabVIEW actor Framework Basics by labvolution. These examples are pretty clear for me now. What I don't understand though, is how you are supposed to provide "real" data These examples use only references and then update using the "value" property This may not be very fast, but is probably still enough for user interface applications. But what happens if I have a player who generates data by reading example of a card and I have, let's say, want to detach this far from the data backup process in a file. How I would pass large amounts of data between stakeholders effectively.

    2. using the framework of the actor with RT:

    In presentations to the AF, I saw that they always mentioned that it was completely "capable RT. While this may well be true for the RT itself system, yet once I wonder how to transfer data from an actor of the RT of a player in Windows. Yet once again, suppose I want to generate data on a cRIO and save that data on the host PC. I will establish a channel of communication between the target myself by network flow or similar? It defies any sort of encapsulation of the AF in my opinion...

    3. set the actors:

    However, what worries me the most, is the definition of the actors. How can you know what is a player in your system? Each card set as an actor? Define you each device as an actor and consolidate all I/o to the breast? Is there an easy way to know how to set the actors?

    4. technical support:

    While working with the examples, I found that the debugging can be quite difficult. I had several cases of "Not executable Subvi" this point through several other live who finally call something dyynamically and from there, you discover that one of your screw is broken. Is there an easy to know what is the problem? I know there are modules for LabVIEW that are designed to turn on debugging part of the actor, but who would not be available in a review of the CLA, where you will have only a base installation of LabVIEW.

    5 root and nested actors:

    Finally, I wonder what root and nested average actor. So far my understanding is that the actor root is the parent actor you cast in the launch of VI and nested the actors are all children who serve the actor parent and are, most of the time, launched since the actor-actor of parent nucleus. Is this correct? Is there a better definition of it?

    Any help on this is greatly appreciated. I'm looking forward to the discussion and interested if you frequently use the framework of the actor or if you have abandoned it even once after using it.

    See you soon,.

  • framework of the actor

    Hello

    Where can I get the version of the Framework of actor that I have on my PC?

    Best regards, Bjarne

    Hi Bjarne.

    If you use LabVIEW2012, the framework of the actor is located at:

    C:\Program Files (x 86) \National Instruments\LabVIEW 2012\vi.lib\ActorFramework

    For LabVIEW2011, you can find user.lib.

    If you open the lvlib and go to properties, you should be able to see the version:

    If you have installed the framework using VI Package Manager you can see as well the version here:

  • Effect on correction of the CJC to use copper instead of type thermocouple extension cables

    Hello people. It is is a kind of "phenomenological" question, lumping together a bunch of real problems. Type of hope that someone had experience try this and can give me an advice.

    I'm looking to make measurements of temperature relatively high speed with very fine wire of type K or N thermocouples.

    I will be very many TC - about 75 in quantity and therefore will be, if it works well enough, wire the asymmetrical (I trading accuracy for amount in light of the SCB-two 68).

    My complete data acquisition system is:

    Computer PXI

    PXI-6225

    (Qty 2) SCB-68

    QUESTION 1: Any recommendations in the configuration of these two NRSE or GRSE? The device, I am close to (but not electrically in contact with) is completely without merit (experience of combustion). TC fine wire is indeed very thin, and their not armoured lengths will be about 12 ". There is no significant EMF/EMI around my experience. I will experiment but just wanted to know if anyone can rule something here...

    QUESTION 2:

    Important points:

    • I want to use type N for additional above K to my temperature range and also because that N-type are available in smaller caliber (0.003 ") and stability welded end to end.
    • Unfortunately, I n ' t has a bunch of N type connectors - if I have to use/buy the N type connectors this is a significant cost (see the stop).
    • My Setup has the TC in the physical location of 'groups' of 7. Given the asymmetric configuration, I have 7 anodes and 1 single "reason" for each "group" - for a set of 8 wires out of each "group".
    • I need to connect on the order of 80-wire in both SCB-68. I try to minimize the number of threads that I have to deal with.
    • Omega does not sell single conductor wire anode and cathode for the N-type as they do for K-type. They sell only duplex son.
    • Omega is also not sell armored bundles of type N, as they do in K-type
    • If I use type N TC and I use the real N type extension wire, it will have to be duplex (because of two previous points) - it's something like 80 PAIRS of wiring, with one of the sons of the cathode on most of the wires not used (because of the asymmetrical configuration).

    It seems that I must consider the following compromise:

    Use the TC type desired N and treat approximately 80 pairs of duplex wire extension of type N OR less desired TC type K and purchase grouped, shielded wiring to minimize the mess of wiring GOLD copper use extension (WHAT?)...

    Yes! Why can't I use the copper wire extension to the fine N TC of the cable type and connect to the TC with a kind of nonmetallic connector (like screws nylon) or solder? The attraction here is that I could use the signal wire 8 drivers together, to each of my TC 'groups '. This would reduce and clean my wiring and not need to buy all type N connectors (TC would be wired, no connector involved).

    It seems to me that I could simply set up the cold welding (CSF) on board the SCB-68 fixed to work on N-type. Copper wire would result of the SCB-68 the TC type N. No metal connectors would participate. Thusly, being only one junctions P/OMEGA-copper and copper/OMEGA-N to deal with the CCM. This sounds like it would be exactly the same as a N-type wiring directly into the SCB-68, except that there may be error between the temperature reading to the CJCS and the junction of alloy copper/OMEGA real. This won't be a significant error because the two locations will be very close in temperature.

    If this "mistake" of temperature becomes a concern I can mount a TC that is unique to the copper/TC junction and make my own corrections (I think...)

    Here is a little schematic text (without taking into account all shunt connections in the CSR circuits...):

    Any circuit anode/channel: SCB-68 Terminal-> extension copper-> (direct connection via the non-metallic connector) OMEGA-P of the N type TC

    Common ground circuit/channel: SCB-68 Terminal-> extension copper-> (direct connection via the non-metallic connector) OMEGA-N to the N type TC

    This idea implies that the circuit board within the SCB-68 has copper conductors, such as the addition of copper extension wire would not create an additional junction.

    Anyone tried this? Can someone offer me some ideas?

    THANK YOU in advance!

    Henrik-

    Thanks for the very useful reply. Yes, I forgot to mention that the lengths of wire extension will be the order of 1 m, then resistance extension must be low, even if common ground is used as part of an arrangement of asymmetrical circuit.

    ...

    Here's my last logic!

    • If my experience shows that the single-ended NRSE GRSE arrangement response or "match" the differential response conservative, I will choose asymmetric for more sampling points.
    • Since I know the extension wire / TC to the ASE will be nearly isothermal with the CBS itself, I would like to use the extensions of copper and accept (and possibly correct?) the error based on the temperature. I would like to use threads, as this I need 7 + and 1 ground by grouping of 7 TC to my DUT (Recalling)-> http://www.newark.com/jsp/content/printCatalog.jsp?cat=c127&page=1199&display=zoom
    • If during the examination of the previous point, I find that copper extensions are NOT practical and I need to use tank extensions of TC-metal all the way, then I choose a TC type K on an N-type. The reason is that there are many more options for tanks, bundled extension cable type K (N-type is apparently a sort of new and not very popular). However if copper extensions are possible, then I'll use the TC type N, motivated by their superior high temperature oxidizing atmosphere stability and the fact that I can get them in a configuration welded end to end to 0.003 "caliber!

    If none of this logic seems faulty or unrealistic, I would appreciate it really more input! I don't know that it will be a lot of work!

    Thank you once again,

    -Dan

    Dan,

    I've marked the important phrase what you're actually doing is moving the CCM of the CBS for the TC/copper connection. Any difference in temperature will directly add to the error.

    However, don't try to save the copper with your approach to 7 + 1, ask IT for another 12 m Ethernetcable guys more and go with 7 * 2 + 1 pair of reserve and make the summary at or near the CBS. IF you need a differntial measument system later, you need to rebuild all connections. (And not just add a new cable for all conical fittings, it is the twisted pair that makes the magic Yes, same vor 1 m!) Remember that you are dealing with µV! And since you want to quick reads without filter a lot of way, do not try to save $10 to about 12 m of cable. Somehow I have the feeling that you try you anyway

  • Temperature measurement and the CJC using thermocouples on a USB - 6229 BNC

    Hello

    I'm trying to get the measurements of temperature using type K thermocouples on the box nor usb-6229 BNC. SignalExpress software doesn't let me choose 'Built In' to the Source of the CJC. So, I must select 'Constant', which means that I then have to follow the evolution of the temperature during the day with a separate meter and adjust the value of CJC accordingly to maintain an accurate reading. Is there a way around that to avoid having to monitor the room temperature at the junction?

    Thanks in advance

    Mike

    Hi Mike,.

    It seems that you have managed to find a solution for you have this problem, which is great news.

    However, for future use, if you had bought the 6229 with massive ending (rather than the interface BNC) then you might have interfaced unit with a block of connection SCB-68 (see link)

    http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/1180

    The SCB-68 has a CYC source built-in, so you might have used in conjunction with 6229 (mass layoffs).

    A bit of in the way, but I thought you may be interested.

    Best wishes to you all

  • Sharing of framework in the Beta3

    could someone already find documentation on the sharing framework, which should be available in beta 3? So far I found only things related to share via NFC but not to share via email, twitter, bluetooth, etc...

    Thank you

    Conny

    I think that the framework 'sharing' you mention is just another case to use the framework of the call, with a few predefined actions (maybe bb.action.SHARE?) and other parameters. If Yes, they are actively working on the finishing document all of these Invocation Framework uses and will be posted the docs for him shortly (I think in a week or two at the most, based on what I heard yesterday).
