• Configuration/installation of resistance FP-RTD-122

  How to configure a FP-RTD-122 to MAX 3.1 for playback of a 44004 thermistor Resistance(normally 2252ohms @ 25 ºC).
  MAX automatically assigns to the beach-328 to 1562 f and then sends the 848 exit ºF 60ºF measured and temperature.

  You must set the string attribute 'RTD Type' to the correct linearization. The module supports the 10 types of RTD linearization methods. There are 5 values for PT100 RTD linearization and 5 for PT1000 RTD. They are:
  PT100, a = 0.00375
  PT100, a = 0,00385
  PT100, a = 0.003911
  PT100, a = 0.003916
  PT100, a = 0.003920
  PT100, a = 0.003926
  Pt1000, a = 0.00375
  Pt1000, a = 0,00385
  Pt1000, a = 0.003911
  Pt1000, a = 0.003916
  Pt1000, a = 0.003920
  Pt1000, a = 0.003926

  The Pt100 or Pt1000 indicates the nominal value of the RTD and the alpha value is the resistance at temperature Coefficient. If none of these options are valid for your type of thermocouple, you must set the channel of range 0 - 4000 Ohms and calculate the temperature yourself.

• Writing the file of the measurement loop, multiple-second 'sleep '.

  Hello

  I do app in LabView 2011 (v11).

  His reading of FP-RTD-122, attached to the FP-1001 via RS - 485.

  Attached app good enough job, but (never enough for me... :-)) when the time between slaughter is long)

  (I don't want to log every 100ms, rather every 30 minutes (1800 seconds, 1800000ms) - and it could become also abuse of the resource to use COM every 100ms).

  App does not multitasking and waiting for sleep to the end, so he could listen to action again.

  For example,.

  I have 30 years 'sleep' and after 5 seconds, I interrupt app (I stop with button loop), but I need to wait for the rest of 25 seconds.

  How I would make this app multitasking ("Multithreaded"), so I thread of GUI (GUI) in frontground and logging in the background,

  and even if it began again sleep cycle, I would be able to stop him without waiting?

  I attach .vi.

  Thank you for further assistance.

  (PS: strictly windows application is creating the folder C:\LOG and use of Notepad.exe.) I appologise if I forgot to translate anything.)

  A loop, not two.  You are famiiliariser of trapping in the inside while loop until the time.  Using the output of the time elapsed in a structure when triggered.  Do the things you want to do periodically in the real case of the structure of the case.

  Wire your waiting time in the target time, not the set start time.

• FieldPoint configuration file

  Recently, I transfer my Labview file to a new computer. My set up has the following features, FP-1000F P-RTD-122 and FP - RLY-422. I installed the latest driver of the Fieldpoint, however, when I try to run my file. It says "cannot locate the file of Configuration Fieldpoint" iak.  . I tried to find my devices using MAX, but I couldn't. I am new to Labview, I was using an exsisting implemented. It worked fine until a few days ago.   I started having problems when I start to use the new computer.

  can someone suggest a way more to come my problem. How do I create a configuration file?

  Thank you

  In the previous configuration, it is possible that the channel names have been changed to something else.  So instead of something like Channel 0, you may have renamed to TempOil, (for example)?

  What is the name of the tag that is used to read from FP in any part of your code is causing the error?  If it matches a valid name in MAX.   You may need to rename the channel in the area of data to the MAX to match.  Even if you do not, it may be a good idea to go through your label constants or controls and rebrowse to the channels again.

• FieldPoint for Labview 2011 W7 - 64 bit

  Hello

  I'm currently having problems running FieldPoint Labview 2011 on running on Windows 7 64 bit system. I installed the latest (6.0.9) FieldPoint driver which is compatible with 64-bit systems. However, when I try to make a simple program (see photo A). I met two main problems.

  (1) I'm not allowed to add a control, or a constant to the FieldPoint i/o Point in terminal (see illustration B). The option is grayed out.

  2) there is an error with the FPLVMgr.dll file that is used by virtually every necessary .vi for FieldPoint (see picture C)

  I'd appreciate any help. If you need to know the application, I have a Thermocouple cFP-RTD-122. I'm trying to implement a simple program to read out temperature (see picture D). E PIC shows my MAX.

  Thank you!

  Juan

  Hey Juan,.

  I see you are using 64-bit Windows, but you use a LabVIEW 2011 64 bit as well?  FieldPoint runs on a 64 bit OS, but does not work in the 64-bit LabVIEW environment.  I would recommend installation of environment 32-bit LabVIEW and go from there.

• New configuration of old computers

  Hello

  First of all I have to say I am new to Labview so, some questions may sound stupid .  I was using an old installation that was FP-1000F P-RTD-122 and FP - RLY-422. I was using an old computer that has Windows NT with Labview 7.1. The computer died and I use now and a XP with Labview 8.5.

  I thought that it will be easy, I have copies only the files that I use in the old computer and it will work in the new, but it didn't happen like that.

  I could not find the drivers for these devices, I don't know if I have a need or not.  When loading the file it can not find the subfieldpoint.vi file. I guess it's what helps my RTD 122 and 422 RLY connect to Labview.

  Any suggestions?

  Thank you

  Fieldpoint drivers are installed on a separate CD.  (I don't remember which version to come starting with DVD LV.)

  Do you have any CD or DVD with your LV installation discs that mention Fieldpoint?

• Application of specification USB-TC01 for clarification

  Dear people,

  We want to clarify a few accurate data on the temperature measurements using the USB-TC01 + thermocouple type J.

  We're just not sure how to use the specifications given to predict the available precision (and resolution) in the following scenario:

  the housing of the sensor is placed with the wire of type J in a laboratory room, and the room temperature may vary between 20 and 25 Celsius degrees. What is the available accuracy and resolution in this case (since comp. cold welding circuit is "in the room")?

  Furthermore, we need to measure the temperature in our experience with Celsius at least 0.05 accuracy and the same resolution.

  If USB-TC01 is not able to meet our needs, you can recommend a product OR different?

  Thank you very much!

  Standard thermocouple are usually accurate to only a few degrees, what are the specifications of your J proposed type?

  EDIT: I suggest to use a platinum RTD with 4-wire as the topology of the sensor connection.

• How to connect RTD (method 4 son) using a 4 x 16 (2-wire) or 2 x 32 (1-wire) switch topology

  Is there a way to switch cables of 4 measures using the PXI-2530 with TB 2631 module, which has only 4 x 32 (1-wire) and 4 x 16 (2-wire) topology.

  Hello!

  The TB-2631 attached to a PXI-2530 module will let you assume a 4 x 32 (1-wire) or 4 x 16 matrix (2-wire). Connection to a DMM with a topology 4 x 32 1-wire you would be able to connect the DMM to the 4 lines and up to 8 4-wire RTD to different columns (32/4 = 8). You should consider CT 2630 if 8 isn't enough; This terminal allows you to assume a topology 4 son 32 x 1, so you could measure up to 32 RTD of the DMM even with this card to a single switch. Let me know if what I said was not clear.

• Can I use a PXI-6224 with the SCB-68 to take the measurements of 4-wire RTD, or do I need a power supply separate?

  I suspect I already know the answer to this question:

  I have an PXI-6224 M-series data acquisition card and a terminal of the SCB-68 block and want to take action using a bunch of 4-wire RTD. Is the power to the power source for these measures 6224, or is - not possible with the hardware I have?

  I know that NEITHER you propose other solutions to my problem: I am interested to know if I can do these measures with the device that I currently have on site.

  Thank you!

  Hello Jeffrey,.

  You have two options here, but it doesn't look like you need some hardware.

  The SMU-4357 built conditioning of signals, but it will not work on the chassis curent you have:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/210596/

  We also have an option with the NI 9217 cDAQ, but once, it gets you into a different platform:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/208804

  We used to have an option that we sell no more - the SC-2042RTD. If you are lucky and have one of them on hand so here's some info:

  http://digital.NI.com/public.nsf/allkb/4FF2C0F8D11B99B486256F4C006DCEA0

  You can also use these two elements in conjunction with eachother with your current PXI card:

• Multiple read RTD with myDAQ

  I'm working on a project with myDAQ requiring three RTD constantly reading.

  Two of Thermistors are 3 wires, the other is 4 wires. I followed the tutorial on the RTD Web site with a difference - I connect the RTD to the analog input. The excitation current is supplied by the power supply 5V on the myDAQ. I measured the current to be 37.3mA. When I open the DAQ assistant and choose all the parameters, the resistance reading is a constant 124 ohms. I held the RTD in my hand, put it in ice water, and reading this has not changed. However, when I provided power to the RTD and checked the resistance with a multimeter, it read 115 and this resistance * fact * change when it is placed in ice water.

  Can someone help me out here?

  I couldn't see the guide that you linked, it seems that it redirected to this forum?  If you were referring to the myDAQ, then you can use a 3 or 4-wire thermocouple, just in mode 2 son like that described in the article I linked.  And Yes, this measure seems to be only possible between HI and COM, not between analog input + /.

• RTD with SC2345 and SCC-RTD01

  Hello

  I have a problem with certain measures RTD with the PXI-6289, SC-2345 and SCC-RTD01 setup. I have implemented a DAQmx task in the project, using the following schema:

  Name: RTD_Temperatures

  HAVE channels 16, 17, 19, 21, 23

  RO = 100

  PT3851

  0 to 250 degrees f.

  1mA external excitation

  Acquisition mode: 1 sample (on request)

  I use a wire 4 PR - 12 RTD of Omega. I've also attached the code what I am about.

  My problem is that I don't get the good value of the PXI for RTD temp. I measure the resistance of the probe (109.3 ohms) with a voltage of 0.109V. Using these values, I checked the source of 1mA expected excitement. By raising the resistance of the probe and comparing it to a table of R/T, the temperature should be ~ 75 degrees (who felt all right). However the "temperature", I read of the PXI was 562. I have 5 different channels, and each channel read the same thing when the probe was connected to it. Without a connection to a probe, it was-400 or more. I think it was just due to no connection. I am concerned about the high concentration.

  I modeled the code after a thermocouple VI we use already and has proved its worth. Thermocouples connect to the other the 6289 through a SCC68 connector. I thought changing the task to a task of RTD DAQmx would be sufficient. The filter is just a smoothing filter. Any advice or thoughts would be greatly appreciated.

  Thank you!

  BLUF: When you use the SC2345 and SCC-RTD01, create a new device in MAX under your PXI for the SC2345 and configure the modules you have in each slot of the SC2345. Create a task in MAX (or project), and then select the SC2345 / MOD #: I # (or something similar to that) as the physical read channel.

  I finally thought to her last minute yesterday! I have been setting up tasks in MAX under the card/slot DAQmx which had connected SC2345. It seemed logical to me; but my assumption was that the module RTD conditioning the signal and an output value (voltage or what not) to the card and the user just read what is on the card. But I had to in order to operate, the installer places the SC2345 as a new device in MAX under PXI devices. This brought a dialog box configure the SC2345 with the location of the RTD modules. After doing this, when I created a new task, new channel options for each module of the SC2345 appeared. Then you can choose what input of the module (ai0 or ai1) channel to read from. Configure the task to read the SC2345 / MOD #: ai0 instead of saying, PXISlot6/ai0 (where the SC2345 has been actually connected to PXI), gave correct results. I don't know what it means that, insofar as what is doing signal between the module and the PXI, but whatever he does, set up to read from the module worked well.

• my channel DAQmx property node missing RTD?

  RTD may be available in the menu shown? I do not have a RTD hung right now; could be the problem? However, I don't have a thermistor or thermocouple and these options appear. I'm putting A, B, C, and R0 by program.

  

  Hi Greg,.

  By default, DAQmx filter properties that are not supported on the devices installed. So if your device does not support the RTD channels, then this is quite normal.

  However, one of your previous discussions spoke the USB-6009 case, so I tried with it. The 6009 supports channel RTD but the property for the 6009 filtering info missing properties of RTD, which is a bug. I dropped the CAR #295521 on this subject.

  The workaround is to set the property filtering node to "Show all attributes": lack of properties in the property DAQmx nodes

• measures of thermistor using modules SCXI-1102 and SCXI-1303

  Hello

  I have a 1303 SCXI front-end module connected to an SCXI-1102 module

  I read the article detailing how to remove bias and pullup resistors to activate measures of RTD/thermistor on the 1303. What did not mention article was the case plug the excitation source, and what is the best source of operating voltage (normal etc., high precision)

  I was wondering where I can find this information, also, I could do several types of measure on the same 1303? I have an analog voltage to a flow meter, and I would like to put it on the same module as the Thermistors

  Thank you!

  Kevin

  Kevin,

  The pulling up of resistors to connect to + 5 V internally.  If the values are not suitable for your application, you can use those.  It does give you much flexibility but.  The 1303 does not give you any other access to any source of current or voltage through screw terminals.

  Pull upward and pull down resistors are networks of resistors Series 9-pin SIP. So you can edit them in blocks of 8 channels for joint measures.

• NI9217 + CompactRio to measure two sons RTD resistance thermometer

  I have 4 two sons PT1000 RTD. How can I use NI9217 with the cRio-9024 to measure the temperature?

  I followed the link below, but I do not know where to put the module in mode 3-wire. Right now I'm getting + -1200 C, which must be wrong. And RTD0-3 are now available, but I need to use all of the 12 stations to measure RTD 4. I would appreciate any idea and help. Thank you in advance. I have attached two screenshots, which displays the property page for NI9217, and only 4 devices can be used in each NI9217.

  http://digital.NI.com/public.nsf/allkb/09E99F60C481D613862572C300637341

  Well, the unit has a range of 0-400 Ohms (she waits a RTD 100ohm) so throw a PT1000 in the system certainly will give him a max value output throughout the day temperature.
