• How to change the constant value for the property node "Disabled"?

  Hi all

  I enclose one vi example of what I'm willing to do. It happens during the event for "left selectorrogrammed 1: changing values.»

  Basically, I created a property to a Boolean LED control node. Once clicked, I'm eager to turn it off so that the user cannot change the value (I have a reset all button for use on that).

  I created the node property for this control for disabled people.  When I'm in the block diagram, I change to write mode.

  I rt clicked on it and said: ' create constant ", he does.  However, the constant comes each time as "Enabled". I tried clicking on this constant and looking through all of that property, but I can't find a way to scroll the values or set the value of this constant to "Enabled" to "disabled."

  I see where you can change the elements of this constant... but I guess there is a way to switch this constant to the value you want... any suggestions?

  Thanks in advance,

  Cayenne

  To change a constant value, your cursor must be in the mode 'finger '.

  You can select this option in holding down the SHIFT key and right-click on the diagram - then select the finger.

  Another way is to put the automatic selection of tools:

  Tools > Options > environment > lock automatic selection of tools

  With this option, LabVIEW will choose the tools for you.

  Play with him a bit to see how it works.

• Acquire the values only when the digital output is high.

  Hello

  I work with test of transistor, whose door is controlled by the digital release of USB6289, related to BNC2120.

  Test plan:

  Door 1.transistor is enabled for 5seconds, with P0.0 for example

  2. then, everything remains off for 1secondes.

  3.p0.1 is used as digital output to activate the circuit passing him curent through in the opposite direction, P0.1 goes high for 3 seconds, PS: Gate is off.

  4. the same cycle repeats again.

  My question is to store values to the output of the transistor when P0.0 and P0.1 goes high, and these values should not change until my digital outputs respective again go high.

  I can access transistor by continiously read out my power supply values.

  and in the State off I want to read AI0 because at that time, my power supply is off, so that I can activate the circuit to pass the current in the opposite direction.

  Again, my question is to gain the output through power value when P0.0 is high and store them until the transistor turns on.

  and even for P0.1, acquire the value of output through AI0, when P0.1 is high and store it until it goes high again.

  Hopefully, I'm able to explain my problem clearly.

  Please help me.

  Think about what States (object:statemachine and determine when to use sequence Structures) do you want from t0... t(n-1), IF DAQmx generates outputs and/or inputs are absorbed and what needs to happen (event timed out), before move you on to the next 'State '.

  type def 'enum' with your different States:

  • initialize
  • wait (the user initializes times (sec) set for States, or whatever and presses button 'Start')
  • T0 (generate DigOutputs, store acquired data AnalogOutput (string output number) the register shift, before moving to the next State > user 'set time' must elapse (Note: the wait function allows you to control the rate of execution of loop and allow the CPU to respond to external events and system tasks and avoid using wait functions at the same time an operation of software...))
  • ...
  • t(n-1) if ' end (made requirement) "> goto 'stop', ' another (not requirement not)" > goto regardless of 'State '.
  • stop
  • write a text file of data (string).

• Impossible to select the value from the search screen (quick select, then) on OFA

  Hello

  We have a problem with a user who are not able to select any value from the LOV on any page of the Oracle.

  1. click the button of LOV

  2. search + go

  3. Select or quick selection nothing happens (error on the Page appears in the left corner of the homepage)

  4. only cancel works.

  Any suggestion would be appreciated.

  I saw a similar question posted Impossible to select the value from the search screen (quick select, then) on OFA

  But unfortunately this is not the answer.

• How to acquire the values of CFP 1800 use FP read via RS 232?

  Hello

  We have an application in which there is a provision of the redundancy of the system. By redundancy, I want to say that I have a CFP-2120 and a host PC. Both are accquiring real-time AI module using concept shared Variable values. Each of these variables is linked with a particular channel of the Module & will acquire the data automatically. Initially when the system is Ok, the PC acquires data from the PSC 1800 using ethernet. Now, suppose that the ethernet connection has been lost, now that the PC will not be able to acquire. At this point, I want my PC to acquire data from the PSC 1800 using RS 232. In this case the binding of the variable with channel won't be of such use. I think that in this case, what I can do is to accquire data .vi FP READ and update the variable by plugging the variable for each channel.

  What else will be the solution. Can someone tell me if my colleague and I are on the right track or if the best solution is here, please share with us.

  The move will be highly appreciated.

  Thank you best regards &,.

• In the dialog box constant value

  Hello

  Is it possible to keep the values in the dialog box once I entered? I mean there is value if I run the script again?

  var myWidth=prompt("PLEASE ENTER YOUR TEXT FRAME WIDTH VALUE (IN POINTS)","")
  

  For example if I get 10, next time, that the default value must be 10.

  

  Not sure we can use const not variable (var)?

  Kind regards

  Kitty

  Well, not quite. Before displaying the prompt, you want to extract the label. So move the line before 04 08 and change 04 to something like:

  myWidth = prompt ("Enter etc...", myWidth)

  and then it should work. Obviously, test it first.

• Search index of the secuence valuation until you reach a constant value table...

  Hello

  I have an arry of secuence RR values (its peak at the time of peak of ECG wave is seconds). I know that the added value of the paintings is the total time of sample data.

  I would like to separate in different charts in the representation of every hour of recorded data.

  I need to get a way to get the index where the number of added values are-online 3600 s (1 h).

  So that I can know the index of the arrays values to get the correct index in chart 1 h values, another index for another hour for an another graph,... so until you get the hourly chart several data can show.

  I hope you understand me.

  Best regards.

  Modulo division is performed by the function Quotient & remains on the digital palette.

  

  Work with tables and data DBL or integer types.

  When I use the method that Mike designed, in my view, the VI sometimes lacks a time transition. This happens with the simulated data that I generate because it is possible that the rest is different from zero. For example, this can happen if the accumulated sum is 3599.4 s and the next RR interval is 1.3 s. Which gives the following sum = 3600.7 s. The conversion by multiples of the amounts of 3599 and 3601. The remains are 3599 and 1 after modulo division. None are exactly equal to zero.

  I've changed this option to use DBL and then look the big negative transition. The minimum value may be with the largest range of RR in the data. However, there is always a great transition close to 3600 to near zero.

• Impossible to acquire the lock on Fluke 45 COM1 series in LabVIEW

  When the ECHO of multimeter Fluke setting is enabled, the following occurs using the Panel to test VISA OR max:

  1. In the VISA sign, a write command is sent to write * IDN? \r to the multimeter.  No error, the DMM accepts the order.
  2. In the VISA sign, a reading command is sent and the DMM previous writing echoes (* IDN? \r) command to the VISA sign
  3. In the VISA sign, a reading command is sent, then the DMM shows the output of the command "write" (FLUKE, 45, [redacted] sn, D1.0\r\n 1.7)
  4. In the Panel VISA, a read command is sent, and then the DMM indicates that the "write" command has been received and executed successfully using default BOM of the DMM (-online \r\n)

  Note that this is quite the same when ECHO is turned off, except that step 2 does not occur.

  Now, it's quite identical to the output during the next show the * IDN? order Tera Term:

  * IDN?

  Fluke, 45, [redacted] sn, 1.7 D1.0

  =>

  (Tera term, does not display the CR (\r) or line feed (\n) as does the VISA Committee).

  Thus, it would seem that the VISA panel communicates with the DMM in the same way as terminal, it is simply not actively reading such as Tera term and requires the user to request a read line.

  What I don't understand is the difference between the behavior of the DMM when you use the Tera term or the Panel test VISA and when using LabVIEW.

  When communicating with the DMM in terms of Tera or the VISA sign, the digital multimeter answers ranging from 1 view state to indicate status 2 (see images below).  When you try to use even the simplest example communication series live or the driver plug-and-play Fluke screws, the DMM remains to view state 1.  Note that the change of State 1 to State 2 happens only after the launch of a connection in Tera term or the VISA sign; so, I think I'm having a problem where LabVIEW is unable to acquire a lock for communication with the instrument series.

  If someone has some, please let me know if you have a way to solve this particular problem.

• single-precision changes constant value

  See attached 'vi '. If I set a digital double precision on my schematic, change it to SINGLE-precision, then enter the valeur.001 inside, he adds values to the right of the decimal point. Why would he do that? I'm using Labview 2011 SP1.

  Display telephone and take just a guess.

  The accuracy is defined in bits and a lot of fractional values is not a translation exact decimal.

  For example 0.001 cannot be represented exactly in the sgl or dbl.

  This is inherent to the representation of floating point and not language-specific. You simply download the closest value possible. Assign the DBL and change the format to display 20 decimal digits. Same difference.
