• Conversion from data type "float".

  In a wireless data logger I collect analog data with a 8-bit microcontroller and sending it as a UDP datagram. The data received in the LV application looks like this:

  \r\n020.43\s002.14\s000.00\s000.02\s ("------" "" display codes)

  0D0A 3032 302F 3433 2030 3032 2E31 3420 3030 3030 2030 3030 2E30 3220 (display Hex) 302F

  020.43 002.14 000.02 000.00 (normal display)

  I want to undress and show values 20.43, 2.14,0.0 and 0.02 in my application of LV.  Try with "Scan of the String" and "Decimal number to the string" but without much success. Maybe I can 'building' my data of the hexagon?

  Any idea is welcome. Thank you.

  Channel scan works very well for me.

  

• Change the value of type Float to String

  The use of FM (model Format) is to cut off the escape null in this case.

  This would also be a reasonable answer, unless of course your sales/technical design has already stipulated that the float should be the number of days since January 1, 1900.

  However, you don't mention that in your original post, so how could anyone experienced that?

• Disable the setting custom step Type

  Hello

  I'm developing some types of custom step and I don't want the developer of the sequence to be able to change them. He should be able to access the properties of the step only which are visible through the property browser. I want my guys to appear as types of NI - where everything is disabled for the user.

  This way I can protect my types to get damaged by an adventurous sequence developer and also give him the freedom to design their own tests using the types I give him.

  Is this possible? If so, how?

  Thank you.

• Conversion of 16-bit unsigned 32-bit float

  Hi, I'm new to labview and data types in the electronics. Due to a shortage of labour in my company, I am required to do it myself. I've been through several labview basic tutorials and examples, but I am unable to do anything properly with labview. Any help is very appreciated.

  I'm using labview 8.6.1 and I downloaded the drivers for modbus. Currently, I am required to read data out of a sensor and write the data to a file. Using the ".vi MB series Master query Read Input registers (poly)", I am able to read the data in the registers. However, the data in the registers are 16-bit unsigned and does not give the "real" value I'm not sure about this, but I tried to use simply Modbus 6.3.6 and change the bit 16 32-bit unsigned type float makes the job of showing the real value.

  So, my question is, how do I get the actual values of the VI? I apologize if this is a simple question but I am new to this and don't have the time to study further in this regard. In addition, I apologize in advance if not enough information is given. Her updated the VI of "Master Series MB query Read Input registers (poly) .vi" that I used to write data to the file, as well as 1 text files, I got is attached.

  Thank you for your help and sorry for any trouble.

  Here's my VI registered under LV8.6.

  You have pretty cables through your VI, but it is ridiculously little handy, easily scalable and uses some Rube Goldberg constructions.

  Your Rubes:

  1. table to the cluster to unbundle converty.  Then grouping to a cluster and then to a table.  No need to go through the songs and dances of cluster.  You could have used the Index table and table build and not had to convert anything to a cluster or backward.

  2. using a constant Dbl to change than one through the digital conversion function to determine the data type for the type cast.  Eliminating the conversion and has created the representation of the single precision instead of double precision constant.

  3 code dozens of times when he should have been treated in a loop of duplication.

  If you use me as a Subvi, your screen real estate will be less than a 1/4 of what it is now.

  You say you want to read a bunch of records that are not adjacent to each other?  You can make several requests of reading.  Write a query command, then read the answer.  Then write another order of demand for various registers and read this response.  It depends on how different readings, you do or how far records of interest are about whether it makes sense.  If you need read a two pairs of registers, which are some distance apart, it might be more efficient to perform a single read multiple registers if they are close together and just throw the records don't care you.  It will be more bytes to read at the back, but it might be faster because it can be done in only one reading.  Or you could do two readings targeting your specific records.  It might be less bytes to read in each message, but it will take more time to make two requests to read and wait for responses between the two.

  I don't know if the limit of 125 records is something to make your device, modbus or modbus in general protocol library.  I want to say that it might be that the modbus Protocol usually means that records the 125 250 bytes of data.  Factor of a few bytes of the command of the response and the checksum, you will be 256 bytes.  Modbus packages are designed to take less than 256 bytes so that only a single byte is needed to tell how many bytes of data will be forthcoming in response to the message.

  With selective targeting of your records to read and using the table of Index to read specific float32 values of interest, you can write the 12 values you want in the file instead of all those you don't need.

• How can I write the value of floats Unitronics vision230 PLC with modbus Ethernet

  How can I write the value of type Float in unitronics PLC Vision230 modbus ethernet (Ethernet Master Query.vi MB) usinsg I read and write register 32 bits, for example, I want to write the value 23.45 2nd Add. MF. And registry MF is the 32-bit registry. I read and write register 32-bit.

  Narendra.

  Narendra,

  Two characters can type cast into a uint16 you VI supports.

  To summarize. Take one (4 bytes). Flatten it to a string (4-byte) divided this string into two parts of 2 bytes each. Cast in u16 (16 x 2 = 32-bit).

  However, if you really want to follow the IEEE standards then you will need refer this KB. His is not that simple, but seems closer to what you are looking for.

• notifications of type push (bb10) has not received

  Hello!

  After having my job to push service, he stopped.

  I can save the user, create the chanel and everything works fine, but when sending notifications, he said everything is ok, but nothing is received the alpha device.

  It worked, maybe it crashes after the latest OS update, not sure.

  Any idea on what is happening?

  This is the answer to push:

  For the slog2, you will need to install the Momentics IDE which is installed with the native SDK 10 BlackBerry. Install this IDE will give you the tools you need to access the device.

  http://developer.BlackBerry.com/native/download/

  1. in the QNX Momentics IDE, based on the target browser, right click on the target of the device. ClickLaunch SSH Session.

  2. in the terminal that appears, do one of the following:

  a. to view logs of current slogger2, type slog2info.

  b. to display the output in real time for the processes that are being debugged (for applications that are running in development mode), type slog2info - w.

  c. to display help on slogger2, type slog2info h

  SSH to the machine and run it:

  slog2info >/tmp/slog2.txt, and then send the slog2.txt

  We are able to determine the root cause of the problem in this thread that was the bar needed to be updated to have XML descriptor:

  
        APPLICATION
         
             bb.action.PUSH
             application/vnd.push
         
  
  

  However, when the BAR file was generated META-INF/MANIFEST. MF was lacking the entrances to invoke target which led to the discovery of the root cause of the problem which was the SDK of AIR PlayBook instead of the SDK software BlackBerry 10. Once the correct SDK has been used push starts happening on the device.

• Convert c# to Java code - Floating Point Arithmetic

  Convert c# to Java code - Floating Point Arithmetic
  
  Hello
  I need to write a c# equivalent in java code. The c# code includes functions perform mathematical calculations. The result of these functions must match exactly with the c# (especially precision) counterpart. Here's a function that requires an equivalent java
  
  Public Shared Function squareroot (string n1)
  {
  If ((n1 == null) |) (System.Convert.ToDouble (N1) < 0))
  {return null ;}
  else {}
  return (Math.Sqrt (System.Convert.ToDouble (n1))) System.Convert.ToDecimal. ToString();
  }
  }
  
  C# two data types - float (32-bit) and double (64-bit) floating-point. It also includes a more specific data type float called decimal (128-bit). The float and double are supposed to follow the standard IEEE 754 floating point standard, but precise figures are different. Double c# has 15-16 digits for precision while the equivalent of java has 53, right? (the IEEE standard reference).
  
  Does anyone have an idea on what java equivalent data types/libraries must be used such that the results correspond with double c# and decimal?
  
  Thank you & happy new year

  This has nothing to do with the IEEE 754 standard, because nothing in IEEE 754 specifies how many decimal places should be used when a value is converted to a string. Simply because the resolution is between 15 and 16 decimal places does not mean that there is always an exact representation of any number of IEEE 754 format to 16 decimal places. In your example, Java chooses to create two decimal places more than c# don't but I bet that this is not a general rule you can count!

  The whole concept of using strings to represent the number seems to be skewed. I don't really see the point. It is mind bogglingly slow and in my view it does nothing for you. You have not yet met the real problem yet! What happens when Java or c# decides to use scientific notation?

  In your situation I would like to change the program c# use 'double' rather than 'chain', then you would find that you get an almost perfect match to all time. I make this recommendation of much written spending year of algorithms in C, C++, c# and Java of signal processing.

• Function of certification and OCA rest

  Hello, I am a student at OCA certification and need help to understand the rest function works.
  
  I read that the remainder (m, n) (http://www.techonthenet.com/oracle/functions/remainder.php) is calculated as: m - (n * X) where X is the closest whole number of m / n.
  
  I ask: why rest (12.5,5) = 2.5?
  
  In my view, the result should be > > > rest (12.5,5) = 12.5-(5 * [l'entier le plus proche de 12.5/5])=12.5-(5*3)=-2.5.)
  
  Thanks for your replies. Kind regards.

  You shouldn't jump to conclusions that fast. First let us check the behavior documented. No speculation that can be found on the net (or even on this forum).

  ...
  

  If n1 = 0 or m2 = infinite, then Oracle returns

  
  An error if the arguments are of type NUMBER
  NaN if the arguments are of BINARY_FLOAT and BINARY_DOUBLE types.
  

  If n1! = 0, then the rest is n2 - (n1 * N) where N is the integer nearest n2/n1. If n2/n1 is equal to x.5, N is the nearest integer pair .

  
  

  If n2 is a floating-point number, and if the remainder is 0, then the sign is the sign of the n2. Remains of 0 are not signed for NUMERIC values.
