MAX is reading my PLC values as decimal type, but they are BCD

I have a Koyo sold by Automation direct plc.  All values of the automaton are BCD, but in the measurement and Automation Explorer, they are read as decimal values.  Does anyone know how to convert, OPC server is on the MAX so that I can read my values, because they are?  The database of the Citadel is useless for me without eigenvalues.  Belvedere offers the possibility of advertising ": b ' to your tags to read as BCD.  LabVIEW tools and it offers a similar way?

Your opc server program should have a specific format for reading the data of the BCD. Here is some info for kepware.

There is an option to specify how the word is interpreted in the kepware opc server program. Here is the info of help files.

  • How to get the updated values of the loops while they are running

    Hello

    I am trouble with a very basic problem, how to access the updated values of the "loop FOR" during operation?  Basically, the VI I is currently working on two sub vis calls each sub VI has a loop for, and the two screws may or may not work for the same number of iterations. My goal is to read the values in each terminal within the loop of two sub VIs, in primary VI. I tried to do this using Global Variables, but in main VI it will display only the last iteration of the two value sub live. Could someone please tell me whrere I go wrong? Is there any other/better way to do this.

    I appreciate any input on this issue.  

    Pass a reference of the main VI control to the Sub screws.  See attached example.

  • read the independent values in a channel

    Hello

    I want to read the value of a chanel.

    I guess that every chanel's store as an array with an index and a value.

    I would like to read a value of a chanel with its index number, then do some calculations, and then write to it.

    For example:

    Chanel 1:
    index value
    1           1
    2           1
    3           1
    4           2
    5           1
    6           1

    start index = 0
    value > 1?
    If no control of the following
    If so do something

    Do you have a sample script to read a unique value in a chanel?

    Kind regards

    Frédéric MANUAL

    OK, so it should work

    Dim oChn, K, value
    "Go to the channel you are interested in.
    Set oChn = data. GetChannel ("Time")

    ' loop through all the values
    For K = 1 To oChn.Size
    Value = oChn (K)
    If (value > 1) then
    "do something
    MsgBox ("value WG 1")
    End If

  • Read the output values after each step runs in the User Interface of LabVIEW

    Hi all

    Development environment: TestStand 2010 SP1 and LabVIEW 2010 SP1

    Problem: is there a way to run the following steps programmatically and get values out of each of them?

    I have already extended a bit a complete interface IO for TestStand load any sequence, choose among the measures and execute step by step (something as an alternative to the steps run selected). What I'm trying to do is to add some actions between each step and do in the UI (I can't change the sequence!), so I start the NewExecution with some previously configured InteractiveArgsParam and option breakAtFirstStep set to true. Eventually I do just something like step over when debugging the sequence and it works well, but I didn't do well a way yet to read the output values of the place...

    So, if I wait before the end of the run I can read my results by treating the ResultObject, but it works only after the completion of the test sequence. Because I wanted to stop after each step, read the values, do some actions and continue to the next step, I've tried to register a running Trace event reminder View Manager. I see that after each step is executed, this event is fired, but when I try to read that a ResultObject returned in the event data it is not filled with values (ResultList seems to be empty?). Is this a correct behavior or maybe I'm reading the wrong way? (It's the same VI regarding the reading of the ResultObjects after the sequence ends and there it works very well for tables, containers and other types of data).

    As I mentioned I can't change Test sequences, I can not add a UImessages.

    What are my options? If the trace event returns output all the values from each steps or is it just used to check the status? Or maybe there's a completely different approach to this issue?

    Thanks in advance for your suggestions,

    Best regards.

    When you manipulate the UIMessage trace (you need this before the return of the event or you will present the race conditions), download myuimessage. Thread. Then call Thread.GetSequenceContext (0, & Iplease).

    And then on the context of the sequence, either go to PreviousStep.Result if it exists, or watch Locals.ResultList.

    Trace events occur between the steps executed step the more recently is the previous step, but it is also a trace event to the beginning before any measure have run at this time, there will be a previous step.

    Hope this helps,

    -Doug

  • Read the last value of a large file of PDM

    Hello everyone!

    I hope someone can help out me with this one.

    I try to put in place a program that can read the last value of one of the large channels of different TDMS files but I just can´t find a way to do it.

    I would appreciate help for my little problem.

    Thank you very much in advance for your support.

    Kasim.

    Hello

    You can use the following playback TDMS Set Position feature included in the PDM API.  This function receives a parameter called "(0:start)", which can be set to 1 to go to end of the file.  In this way, you can read the last value written to the PDM file.

    I hope this helps!

  • D2KWUTIL Read_Registry - only reads the string values? How to read the binary?

    Hello, everyone!

    The service works very well with string values (that is, type REG_SZ registry).

  • Can I 'read' a control value that has not been committed?

    In short, I would like to specifically to bypass convention of LabVIEW which is a value only committed when the user moves the focus, press the button enter, click on a button to increment, etc..

    My specific scenario is I want to respond to button Up/Down/whatever of the events for a given control and enter the value so I can update the graphic interface in real-time as numbers are entered.

    I had thought about using the "Selected" the reference FocusObj property to remove the focus temporarily to force the value to be committed, but it seems to do nothing, at least not the way I use it. I also tried to use this property to choose something else entirely before selecting the original order, but once again, nothing.

    I imagine that an XControl MIGHT be able to do something like that, but I will abandon the effort before I'm dipping my toe into these waters.

    TLDR: Is it possible to cheat and capture the contents of a control, while the user is still typing in there?

    In addition to what nathand said, it is perfectly correct.

    If you need capture an event in the event structure, instead of 'Change of value' you better to handle the keydown event and take the property Numeric.Text for the property Value will not be changed, but you will have access to what is indicated on the control.

    If you do what johnsold says, then the value will be updated after each character, this only applies to controls of the channel.

  • DLL, interfacing with which coexist value and reference types

    Currently, I'm working with a supplied DLL.

    I have header files and everything and the DLL import wizard does a decent job of importing DLL functions but there are certain types of data that cannot simply be dealt with.

    The DLL requires the use of a data type that is a structure with data reference and value types.  I could theoretically replace the references by simple U32s, but much of the information required in the data is in the data referenced by the pointers structures.

    How can I do to implement this light how do I have to be able to transmit data to the DLL in its original form (value and reference types).

    I have something like the following:

    struct point {}

    Int device,

    * The point then

    * Previous item

    * Data Datastruct

    }

    I downloaded the Microsoft WDK, CVI and Visual Studio 2008 available.  I'm not very experienced in this end of things...   I will dispose of Structs with pure value types, but how do I get the data in reference types?

    I strongly suspect that I need a wrapper DLL, but how is the best way to go about this?

    Shane.

    Shane,

    It's always a problem when you use a DLL.

    If you do not have the sources of the DLL, you must trust the description of it.

    (Or you will have to disassemble to be sure, which is forbidden in most cases )

    If (in your case), the linked list is handled elsewhere than your Labview code, you will get in trouble. (Added, deleted, or modified items)

    I don't know your DLL. But usually the data is stored inside the DLL. For example, I have a DLL function that reads a counter from a DAQ hardware. If I reset it (on its reset settings), it sends back the nuber of counted events. This DLL must not be initalized.

    Other hardware DAQ I use must be initalized using its DLLS before you read all the values.

    It all depends on the implementation of your DLL.

    You have a detailed description of your DLL?

  • dynamic action sets the value of the element, but not save to DB on submit

    I'm working on a page where the value of several to show only the page elements are defined using a dynamic Action.  They are set when the user selects a value in a list of selection (and is based on the value of the selection list).  Dynamic action is triggered on a list selection change event and then runs the real action "set the value.  The selection list displays the names of sales representative.  The three fields dynamically filled are the org structure (that is, their chain management).

    For the action to set the value, I use a defined Type of SQL statement:

    Select VP, DIR, MGR

    of SALES_ORG where SSR =: P20_SSR

    In the affected elements, I have fixed Type of selection to the 'item (s)"and the value of the Item (s) for 'P20_GVP, P20_DIR, P20_MGR.

    Dynamic action works fine for the display of the page (that is, when I select a sales representative in the selection list dynamic action properly updated only display value fields three).  This page is a form in which the user submits information relating to the rep.  When the page is sent, all fields are filled in a new record of DB with the exception of three that were populated dynamically above.  These fields get the values NULL.

    When the dynamic action updates the values in the three fields is - it does not set the value of session?  Why these fields don't are not taken into account in the submit other ideas > process Page?

    I use 5 APEX with Chrome on Mac (Yosemite).

    Thanks for the note.  I didn't only display the items could not be used in this way.  I think I'll take a different approach with the design; given that the org structure is in another table that I can simply refer to that by rep when necessary rather than saving the information uploaded to the page of the form.  The reason why I have not fill the screen only the points of loading the page is because I don't know what the values should be until the user selects a sales representative in the selection list.

    I'll change the design to one of the following:

    1) change the display only items of standard text field.  NOTE: if I make the text read-only field that causes other problems when loading (I get the message "violation of protection Session state").

    OR

    2) do not include org structure in the download folder and just refer to table org Rep when necessary.

    Thank you!

  • Canon 5 d Mark ii Images with the value of the white balance fixed. When they are imported into Lightroom, the value is different.

    If I take a shot with the fixed value of 5200K WB (5 d Mark ii) and import into LR 2015.2.1, happens to 4850K. No presets or applied adjustments.

    No idea why? How can I solve this problem?

    Rich

    All raw converters use four multipliers of white balance RGGB tinted and embedded in the raw file EXIF data to set the white balance and 'calculate' the temperature values displayed inside the module development LR WB.

    Scroll down to the "White Balance" section of the DCRAW tutorial PDF here: GUILLERMO LUIJK > TUTORIALS > DCRAW TUTORIAL it's all so raw converters all the rest of the white raw file and 'calculate' the temperature and tint values.

    Here is a Canon 5 d MKII CR2 file with the White Balance adjustment 'in the know' behind closed doors:

    (Data EXIF Maker Notes)

    The setting "As Shot" WB in LR shows a Temp of 4800 reading, which should produce a slight visual difference that the planned in-camera closed 5134 parameter, correct?

    However, with the LR settings file, "As Shot" above the white balance CR2 is the JPEG file in camera perfectly on my Canon 5 d MKII (raw + JPEG file format). It's just that Temp readings do not, because they are "calculated" four RGGB multipliers. Each raw (LR, opening, C1) converter will probably show the values of temperature and tint different, since they are derived by using "reverse engineering" of the manufacturer of exclusive camera raw data structure and camera sensor response file.

    Keep in mind that the spectral response of the camera is affected by changes in batch. A Canon 5 d MKII body can produce slightly different WB as one another using the same exact settings. Rather than depend on private clos or LR presets use a good white balance card or the ColorChecker Passport to 'calibrate' LR white balance settings standard shooting conditions (daylight, cloudy, Flash, etc.). For critical projects draw card of the white balance at least once for each unique lighting condition. You can then determine the correct inside the LR setting and settings of synchronization of the World Bank through all the images taken with this specific lighting.

  • E-mail messages cannot be marked as read automatically when they are read?

    Instead of having to physically push a button to "Mark as read" after the opening of each email, why didn't they just mark themselves automatically as they are clicked on and read? Not which seems logical? All other mail clients I've ever used has been assumed that when you click on an incoming message, IT has BEEN READ. This seems so obvious bleeding. It is ridiculous to have to press a button to mark a message as read.

    I have worked with Macs since the 1980s. How old are you? Maybe if Thunderbird has better layouts of menu that I should not spend 2 days rummaging the Prefs for something that should have been a default setting, as on any other client of e-mail on the planet.
